1991 Camaro problem starting

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?

it idels around 40 PSI but as soon a I give it gas it cuts out

bad fuel pump is my guess

bad fuel pump is my guess

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!!
