1991 Camaro problem starting

RedWind · #1 02-03-2008, 06:06 PM

I just bought this car and it ran perfectly for about a day then it starting cutting out, and then it got worse and when I would push on the gas more then just a tiny bit it would start to cut out until I would let off, now it wont even turn over, I checked the spark and it good I changed the filter and thats good, I check the pressure and that is also good, now I am stumped it went everything seems to be fine but it wont turn over.

sorry for double post

alright now it is starting but when I go to rev it up it chokes out you will feel it accelerate and then the acceleration will cut out and then the engine will cut out.

miles, engine size & fule delivery system please.

What is the "ok" fuel pressure reading?

its a V6 3.1, fuel injected, it has 150,000 on it which is low for that old of a car

So what is the fuel pressure at?

Ehhh,

For the giggles of it, check the pressure regulator line for gas.

Update:

I did a tune up, and filled my tank and added water remover and I got it to run now, but when I rev it up and around 2500 it starts missing and lights pulse with the miss.

I dont know if you solved your problem but if u havent, I would check the EGR system....it kind of sounds like you're getting a signal for the EGR to turn on earlier than u should....Try disconnecting the wires going to the digital EGR valve..Im just as stummped as you are...let us know if u solved the problem...It also sounds like you're not getting enough air...I would check for a serious vacuum leak somewhere...Take out the IAC motor and reset the pintle....another thing...I would check for a code in the computer even though the light is not on...there might be something there believe it or not...Im also suspecting that the ECM might be going...hope u fix it!!
