95 Z28 110K miles. it will crank the first try but it wont turn on. it fires up pretty easily the next try every time. this only happens when its been off for a while, like overnight. i turn the key forward to get the fuel pump flowing before it cranks btw. i think its on stock plugs and wires .

any ideas?
thanks

 

Do some checking on the fuel pressure (with a test gauge).

 

Next look for leaking injectors.....if it only does this from sitting over night ...
The next time you let it sit over night..when you go to start the car hold the gas pedal to the floor then
turn the key to start the car

 

thanks for the replies, i'll be doing some minor upgrades on it this weekend and will try out your suggestions. i'll report back with my findings.

thanks again

 

well, this one is solved. i think it still had the original air filter . swapped in the CAI from my old Z and the car turns on easily every time.


thanks for the help
