Like the title says, I boned myself. I got a supercharger kit and installed it. I go to crank it, no start. I kept trying and trying till the battery died. No f'ing start! It almost catches sometimes, but no go.
Now I noticed two things, 1.) there is a lot of air coming out of the valve cover pcv nipple (blown rings?), and 2.) I pulled the spark plugs out and they were wet and black, smelling like gasoline, switched them out with another set, cranked it, no start, pulled these out and they are also wet with gasolne.
What is wrong, what do I do?
Had a similar problem when I hooked up my s/c kit. Try leaving the tmap sensor harness unplugged from the tmap sensor (sensor on the intake manifold next to the block) until you get the car tuned or reflashed
Is it tuned? If not thats the issue.

That wouldn't cause it to not start. I think he's got something else going on. Double check for a pinched wire around where you where working. And is the sucurity light on?flashing? Also have you tried holding the throttle open while cranking?

That has never been an issue.
OP, it sounds like you are not getting any spark. I would start checking over your ignition system, look for anything abnormal. After that i'd just the stock fuel injectors back in and see if it'll start.
its an old concept. time for something new to take the reigns. - Z yaaaa
He didnt give us much info. I really doubt that 60's or even 42's would start in an untuned engine, I know that some people have got 36's to start untuned (even with the map plugged in).

Well when itried at first I had the IAT and MAP sensor wires unplugged. Through my frustration of having a npo start I decided to hook up the original MAP and IAT sensors. It was not until this morning I read your post that I realized the MAP sensor is out in the open registering 0 vacuum and therefore telling the PCM that it needs more fuel! Probably why I have fouling and a no start.

Noi it is not tuned. I was trying to get it going so I could take it to get tuned. Like Tinkles said, I have never heard of that being an issue.

I double checked all the wiring and the security light is not one. I did try to open and close the throttle and that was when I had my near starts.

I checked the spark on all four and they strong, but ithe plugs are a litle black now since they had gas poured on them from the rich condition.
Leafy, it has the injectord from the kit (36#)
When I go home I'll unplug the MAP sensor and try again. If no go, I'll do what the master tech at my shop said and run vacuum from the throttle body adapter to the original MAP sensor. If I still get nothing, then I will switch the injectors and try it both ways with the MAP sensor. After that I don't know.
Also is it normal to have an increase in blow-by coming out of the PCV nipple?
I had same issue,I had to unplug the Map sensor,By then it was flooded,but after a bit it started and ran..
And did you make sure to cut a slot out of the intake gasket for the PCV breather and put some sealer around it so it makes a tight seal.

Yeah it seems I flooded mine also. I opened up the spark plugs overnight and today so it can dry out.
I did cut the gasket and put RTV around it, although I am wondering if I might of over done the RTV.
What injectors are you trying to run without a tune? Sounds like it's just too rich to me and is flooding the car out. I'd try installing your stock injectors back in the car and see if it starts.

Yeah definately too rich, lol. I have the injectors that came with the kit. I believe they are 370cc (or approximately 35.2#). That is plan B, putting the original injectors back on. If it still doesn't crank and it isn't flooded, then I got bigger problems.
Iv got green tops, 42's and it wont start with them in there. It just floods out like some have mentioned. Your gonna need to scale back those injectors to get it to start.

So I might need to put the old ones back on, get it tuned, and then swap the kit ones back in.
You can do that. If you are gonna drive it to the dealer for reflash then stay out of boost. Id recomend you to tow it though. Or if your gonna tune with HP tuners then just scale back your injectors and try again.

So I have bad, good, scary, horrible, and enlightening news.
Bad: I had charged my battery all day long and before leaving work I decided to test it. Apparently all that cranking last night put my battery on death road.
Good: So I got home and disconnect the MAP sensor, still no go. So I decided to switch out the plugs and Eureka! It fired up, but have a lot of valve noise and it was rocking a lot.
Scary: As I was prancing around with joy I turned my head up and saw SPARKS Flying! I look, the supercharger pulley is rubbing against the hydraulic tensioner upper bolt! WTF! I pull the charger off, loosen the alternator bracket and try to move it over. The pulley cleared but the belt did not line up.
Horrible: So I decided to try a see if the intake manifold had some play to it. I loosen, nothing, so I put it back on. Tighten one bolt, two bolt, three bolt, four...SNAP! 0o0 Ho-ly $#¡+! Snapped a short stud clean and clear, flush againt the head.
Elightning: Well lets might as well pull the manifold off so I have more room. As I pull it off I see a trail of oil from that center hole to cylinder #3. The RTV didn't sit right and leaked. Also the little hole was half clogged with RTV. I over did the RTV. Now I know.
So now I know the engine is not dead (yet) and I did a poor job at gasking the intake manifold.
Well least it runs...Sorry about the broken stud..Let us know when its all up and running good for you
I managed to get the stud problem fixed (used the original studs), but the supercharger pulley rubbing has become a big issue.
Here is the link to the new thread on that problem:
Supercharger Pulley Rubbing!!!
Thank you all for all your help!
She's Done! Just need to get her flashed and I'm good to go! Thank you all for your help and advice, I greatly appreciate it.
