I am back guys, havent been to the forums in a long time. Anyways a little while before winter had came my car started to act up.

87 trans am 305 v8 700r4

Alright so first problem ive got, when my car sits for a period of time, say over night. Or even a few hours when I go to start it, it doesnt want to start right away. Like its not getting gas or something, itll just keep turning over unless i turn key on and off like 4 - 8 times to get the pump going. If i park it for an hour or so, itll start right away but say I park it and leave it overnight, in the morning ill have the same starting issue.

That has always kinda been an issue with it.

Then after awhile now when I have my car running, it will idle just fine, but as soon as I give it a bit of throttle it seems to hesitate, want to stall. and its seems relatively delayed aswell. It got worse the more i drove it.

What do you think my 2 solutions would be? First issue seems like its a vacuum line or something, not keeping the gas in the line and draining back and my second assumption would be maybe my fuel filter needs to be replaced?

 

Check the fuel pressure & see if it holds it after the engine is off.

 

How do I check it?

 

Go rent a fuel pressure tester from auto zone and attach it to the fuel rail fitting.

 

Is it fuel injected? I guess carbs were still available on 87s.

 

So ive tryed to start it for the first time since early november since its not to bad where i live and im getting nothing now. turning over fine, just not sputtering, turned the key on and off atleast 50 times already. I am starting to get frustrated.

 

Like others have said check the fuel pressure.... It will give a idea what the pressure is and eliminate a problem. Have u tried putting a touch of gas in the intake and seeing what happens? It could be a weak or bad fuel pump? Start with the basics, Fuel,Spark,Compression.

 

How much pressure should there be?

Its fuel injected.

If its a pump, itll cost me $90 and alot of labor
