Our 95 Corsica that we just purchased from individual is having problems with starting back up after running for a short while. You can start it up in the mornings or after it has cooled but then after driving for about 30 minuets and you shut the engine off wait for a min and try to start it back up, it just turns over and over. Now I have figured if you push the accelerator to the floor and start it then it will start but a choky start puttering and putting a small amount of black smoke out smelling fuel during this time. Then it idles out and runs fine and does not shut off until you turn it off and it all starts over same routine. Also the check engine light turns on and off while driving but performs fine. We have put it on a computer and comes up with nothing had multiple people look at it and nothing changes fuel pressure regulator still problem persists fuel pump is good and pressure seems fine. Do not know what to do and this is a major problem for us. Could you please advise us on this? Thank you, Chad

Sometimes sensor will not throw a code when they are faulty, so with that being said, I think you should check the throttle position sensor, and and the iac(idle air control valve. Make sure you arent starving for air, check the airbox and filter. Check the accordian hose going from the airbox to the throttle body for cracks and holes, keep me posted please

Thanks for replying. Now this afternoon it fired off some kind of blast under the hood while trying to get it started then put out a lot of black smoke from the tail pipe. I will take in account what you said but it seems to be getting worse and we need this car for work and child to school.

Yes, you must check those things, I do believe its starving for air, you can start by checking the air filter, and accordion hose, easiest stuff

Hi chad, I don't believe this is anything "major" , but it will take a little detective work. I didn,t understand what you said about the pressure regulator, but when this no start condition happens it is necessary that we check the fuel pressure and for spark , I will show you some easy ways in my next post. but. I am thinking maybe crank sensor, cam sensor possibly fuel pump relay or regulator, but we need to do these checks and get back to me with you findings please
