OK before i been up here about fixing my o-rings thats fixed, well that issue is solve so my new issue is my car at start up and wants to give me that old chuga chuga chugaa vroom thing. I was wondering if it could be my fuel pump? This is kinda brand new to me and even when i look at my Haynes manual (garbage) at the trouble shooting section i see nothing relating to my issue soooo again you guys are thee experts i fix several thing with you guys help and well i need it again because this is my only car and i have welding school in the morning in this is my only source of transportation......till i start working at the shipyard...yay get to make some real money....i know all irrelevant....but again i need you guys and the basic issue is the that chuga chuga chuga chuga start issue so again thxs guys

i think i did pretty good being tipsy...but thanks anyway English teacher for not help at all, Am sure you still understood my point of the issue. Its not as bad as your making it.
you need to be more specific than 'chugga chugga vroom thing'.
I can think of a few situations that are completely different that would fit this description.
Ok, Sry skwirl,ill be more specific. Ok , so the problem started after i got some gas from bp. I perfer premium gas, so that's what i use. SO basicly in a nut shell i cut my car on now and it sounds like its struggles to turnover...but it does turn over Meanwhile i would smell gas too..as if i flooded the engine . Ok while driving, the car's idle would drop down to 300 rpm and shoot back up to 1k rpm then to 800 rpm which is the normal idle. Today after class i started i up, Same symptoms occurred,but this time the idle didnt drop as bad, it was like 600 to 800. So after i really ran it and came to a stop light, the idle stayed....normal.... My next guess is bad gas or my fuel pump gonna die on me, and i hope not cause i don't know how hard it is to repair. SO as i reiterated before HELP
hey skwirl, i would really appreciate your input. I understand your probably busy with rl issues but you seem to be the only one that help. But heres a update drove it today, and i smelled gas exiting threw the exhaust. I went to auto zone and told one of there reps and i told them what i told you guys and they think its bad gas. So i bought this treatment stuff called iso heet that removes water from the gas also with some lucas complete fuel treatment and applied both to the engines gas. After that i just ran it, and it ran normal: idel at 800 and would run like normal. Guys i dont know am just baffled...it gives me a ruff start after i leave the car alone for like 30 min then it struggle to start intill i give it gas then it wants to run like normal....and yes a am tispy again....am sry guys i do this after i get out of school and stress is a major factor in my life so VSQ helps laters
pull your spark plugs out and see if they're a funny color... ie. black.
if they're black, change them out and see if that helps.
any check engine lights or anything when the car tries to start and has issue?
the only other thing I can think of is check your oil and make sure it isn't milky... like really runny and drippy.
if it is, the oil is diluted with water/coolant which usually means you have a blown headgasket/ cracked head which is a serious problem.
What happens is when the car is cold, it'll have trouble starting because coolant has leaked into the chamber. when you start the car, that plug is temporarily fouled because of the coolant. once the coolant is burned up, and the leak seals when the engine expands from heating up (roughly 30 seconds or so) it'll run like normal. When the car is at operating temperature (195*) and you shut it off, then turn it on again it won't do it. But if you do a cold start (car has been sitting for 2 hours or longer) then it will do it...
somehow from your description, I don't think you have a cracked head or BHG... if it has trouble starting all the time check your plugs and we'll go from there.
ok cool today i just bought some spark plugs- Boch iridium- so tomorrow am gonna change them and let you know the results. O by the way thanks alot skwirl considering your the ONLY on that helped.
o and theres no engine lights ment to add
what did your old plugs look like? did you check them before you bought new ones?
No i didnt but i just replaced them today and the old ones were kinda black....but heres the kicker! After i replaced them, hooked everything back up, tried to start it and it did the same thing it did before...chug chug chug vroom. I checked the oil and its looks normal color. Is it safe to think that the fuel filter plays a part in this? Am really baffled and being am not as mechanically inclined as your are am actually really scared as to what the next possible issue could be...
And another thing to add, as the car chugs, in order to save it from dieing i have to rev it up a 2 or 3 times then it will resume normal idle...i dont know but it seem like its not getting enough gas? or to little?
I am going to guess he has the problem I have. Been going on for 2 years now. Where I am sure it is the pump. Start my 2.4 up and it idle fine. Maybe a little up and down. Blimp the throttle and coming back down to idle it almost dies. Catch's itself. Then idles fine. Pull out of the drive way and get 10 feet giving it gas it just dies more less. Let off gas give it gas again and will be fine till shut off. Start it back up in which it won't rev. Though will idle. Try to take off and it just jerks and sputters.
After about 10 secs it is normal again. The other problem it has is it doesn't pull from 4k to the rev limiter like it did. It just more less has no balls and the power curve goes flat.
Ok check this out...i changed the fuel filter....looked at the old filter and the @!#$ was disgusting. Even when i poured the old gas in the filter the @!#$ came out DARK BROWN..WHOAA anyway ...pluged the fuse back up...turn the car on to start and listen to the beautiful priming of the fuel pump...turn it on then boom jumps on like normal! yes!! wait the check engine light jumps on WTF...another issue. Test Drive: i drove to autozone, it ran much better..WAY BETTER..., So am at autozone, borrowed the code thingy...code pulled up p0200 which translated to Fuel Injection Circuit Open....how in thee hell do i fix that? SO anyway i returned the code thingy and headed back to the car.Started the car and it did that same bull@!#$ i was trying to fix....WTF X2....but the even weirder part....the check engine light went away.....am SUPER CONFUSED. The Idle is fine at a stop, It runs MUCH STRONGER (now with the new plugs and fuel filter), revs from beginning to redline no prob, But starts up like its retarded.... Skwirl need ya again dude!
well, even though your pump may be good now(only way to know is current ramping which is out of your realm, no offense) it is probably on its way out. if the filter was clogged/clogging and the pump was still trying to overcome it the pump gets overworked and heats up, which melts the solder connections internally on the spinning mass, which then flings the solder off and you loose the connection, which is how a pump dies(most of the time). so your pump will probably go on you within the next few weeks/months, but also may not...just thought i'd warn you.
as for fixing an intermittent(supposedly wiring) issue, you would have to track down the circuit, but without knowing if you have a meter or an idea of how basic circuits/electricity work, idk how to help ya out. if you had an issue with a fuel circuit like an open, with the injectors, i would think you would misfire(so would everyone) but you don't have any emissions or misfire codes...but something to keep in mind, components go bad before wires do 90% of the time. also, i would have your fuel system properly cleaned...probably have some junk in the injectors that may be giving you some issues...a nasty filter like that to me means clean the fuel system.
also, just cuz i'm curious next time you start the car, keep the throttle slightly open, but not much. i kinda wonder if its a sticky or built up iac...
hey dave no offense taken dude its cool i just have one goal , to make my car run normal. Ok i did a bit of research and basically it pointing towards a dead or a couple dead injectors i.e as i explained before when my check engine light came on and i checked it it was a p0200 code , and that was a open circuit code with the injector but it didnt say which one that sucks.. but anywho my car runs great after i get pass start up. But as the internet says,they said i need to check my injectors to see for an open one but i seen ways to check for that like pull the fuel rail off them cut the car on and let it prime then see if any gas comes out of either injector then that would be my bad one to replace. but hey thats all i got for being mechanically decline i look for your response skwir; thxs dude laters
i would also unplug the injectors one at a time, then and it should get worse when you unplug em.(unplug 1, then plug it in, then unplug 2, etc). if its an injector, one of em it won't get worse. i would also do the thing you wanna do though about pulling the rail out. just remember you might wanna replace your o-rings if you pull em out.
ok i will, i just wish injectors were freaking cheaper...86 dollars a pop...
i would get em from a jy and just have em cleaned....once you verify it is an injector, i would just get 4 from a low milage car at a yard, and have em cleaned and like i said, i would still get a good fuel system cleaning
Didn't know you were setting a code. But that could be set from a broke wire to the injectors from the injector driver on the pcm, bad injector driver or as you said injector. Getting a set of low mileage injectors should be fine. I wouldn't bother cleaning them. Unless gummed up some. Then just soak them yourself for a few days in injector cleaner. Taking a AA battery cycling them a few times. After a few days use the battery to hold them open. Blowing them out with 40psi of air.
Just keep in mind cleaning a injector. If you send them off or do it yourself won't make a new injector. A injector is similar to a door buzzer/tattoo gun where they can just wear out. That is the thing with reman injectors. All they do is pull the pintle caps off and replace them. Then pull the filter screens out of the top. Clean and put the new things on.
I didnt know you can do all those things! Thanks for the info...ok time for the update!.....THERES @!#$ GAS IN THE INTAKE MANIFOLD!!....i just getting rdy to change out the fuel pressure regulator and am starting to smell a feint smell of gas...so i take of my cai and am looking at the throttle body and theres a liquid film around the plate, so i open it and low and behold theres @!#$ GAS...How in thee @!#$ did that get in there!! No wonder my car belched out the smell of gas it was ingesting it in the intake manifold.. Now guys this cant be normal right?!
I called up a old motor head friend who pretty damn good with cars and i explained to him my situation, and he said it could be the tps....i think hes pretty close, hell even the obd code p0200 said that could be one of the variables either that or the fpr but if that's the case of the fpr then my car would have terrible acceleration and i couldn't really drive under normal condition's right? well anyway there's freaking gas in the mani and i need you guys again...thxs
it sounds like an injector is sticking open to me. my stock ones have this problem (running them right now actually) just effects startup for me though. when you pull the plugs out use a pen light and look at the pistons and see if one of them is wet or more wet then the others . hope that kinda helps. good luck with the fix
dude anything help and it seems like i need to do that. but question, you said you have the same issue? you have gas at your throttle body too? why didnt you fix it dude why!!naw antwa yeah mine does it at start up too but runs strong, but i want it fix so bad dude i miss my turn key then vroom dual exhaustness. but hey i got my instructions, if i plan to take off my fuel rail i might as well change the fpr to sence i have a new one...but thats tommorow, thxs nate o if anyone have more ideals layum down please for my sake thxs
Could be a bad fuel pressure regulator. I had a similar issue each time mine went out. I could pull the vacuum line off and gas would squirt from the nipple, due to I assume a torn diaphragm.
"Oil Leak ? What oil Leak ? Oh, Thats Just The Sweat From All The HorsePower!!"
i dont have gas at the throttlebody just start up bull shia. i have new injectors for the supercharger, i finnally got through emmissions yesterday
