yeah, Ignition switch is what it sounds like to me i've heard of people doing that trying to start the car with a screwdriver. I would think it would be a great way to mess up your switch even further, though by the same token wonder if that works if you don't have your keys handy.

something else i just noticed, he said his car had a manual tranny could you not push start it and bypass the ignition switch entirely. Or would that not work, not very versed on the concept of push starting a car so don't know for sure just a thought when i saw the manual tranny part.

you can push start any car. you just have to know how to wire it up. mine is a manual that i converted to push start (and not the key turn then push, i got rid of the ignition cylinder completely) all you have to do is know how to wire it up. it's not that tough.
as far as the other thing you said bill, about starting the car with a screwdriver and no keys, whether or not it works isn't the concern. the concern is more of how you'd disable the steering wheel lock.

true, would be a bit of a prob if the wheel locked on you.

Get yourself a test light and follow the diagram.
If you had the starter recall done you will have an extra relay mounted to the radiator support that isolates the ignition switch. If you follow the purple wire on the starter and it goes directly into the harness you dont have the recall done. There for there is a good chance the ignition switch is shot.
Dont totally rule out the starter, I have seen them work by jumpering with a screwdriver but not the key. Not enough amperage to engage the starter through the key circuit.
Just be sure that you are getting 12v at the purple wire on the starter when the key is on the start position. Make sure you press the clutch too.

I'll put money on the clutch safety switch too... seen it fail enough times.

Sky, you say you can push start any car, you can't push start an automatic.

sky hook was talking about a pushbutton start.

Oh yes you can push start an automatic it isn't pretty and it will hurt the car but you can do it I have seen it done.


The proper way of using the word seen. It is not I seen it that would be I saw it. He has seen the car is the right way to use the word. English class is Cool. By the way thats my sig

Thank you all. I replaced the clutch switch while i was in there (220,000 miles later...yep it was factory lol) and the solenoid was going bad on the starter. New starter and she's up and at it again!

So, why would anyone want to do it then.

Btw, i meant if push starting an automatic isn't pretty and would hurt the car, why would anyone want to do it .

ive had 3rd gen. 4 jbodies, 3 were manual trans, i had to replace the clutch safety switch on all 3 of the man. trans ones i had..

same with the back up lamp switch come to thinkk of it.. that is off your topic though.

good luck with it man,

I hate to take a post off topic... but technically it's not possible to roll-start an automatic car due to the direction of the vanes on the torque converter. They point the wrong way (to use the transmission to spin the engine, that is), and they only spin in that one direction... Unlike a manual car which you can roll, then pop the clutch to use the motion of the wheels to help turn the motor.... (a roll start)...

If you push an automatic, it just rolls. You'd have to somehow magically make the torque converter spin backwards, and turn the vanes around too, to make the fluid spun around by the transmission turn the engine over... the fluid alone won't turn the engine enough to start it.

Now a CVT or direct chain-drive automatic transmission... maybe it's possible to jump start those... but an automatic J-body? Just not technically possible.

Thanks Lenko for clearing that up, that's what i thought too. Especially since i'd never heard of it being done. Push starting an automatic that is.

along those same lines lenko ( and boy is this about to get into threadjack territory...) but what if you could put an activation switch on the TCC? I've never really cared that much to look into how that system worked, but couldn't that lock the converter and essentially make it possible to turn over the engine?

Total threadjack

Even if you could lock the torque converter clutch... the gears themselves are engaged by fluid. So simply locking the TCC isn't enough - you'd have to have fluid pressure to engage the gear you want too. Besides... you know how fast the car's going when the TCC engages? 35mph+!! So you'd have to get the car rolling that fast to even attempt it...

Really old cars (my dad's 50 Meteor) had a second transmission fluid pump down by the driveshaft that built up transmission pressure when the wheels were turned - so you COULD push start an automatic back then. I haven't seen a car with that setup since the 60's... so don't try to push start an auto... no fluid = no lubrication = dead transmission.

I've seen a few automatic race cars push started LOL. They didn't sound happy about it though.



I used to race cars, now I race myself.

could always get it at the top of a hill, and get it rolling down the other side. But then, you'd run the risk of the steering wheel locking on you. Btw Hypsy, Bill@!#$ is spoken by someone completely oblivious of the reality around him. I completely disagree with that.
