1994 camaro z28 starting on 2nd or 3rd
Hey everybody, does your camaro start on the 1st try? . Or did u used to have to turn the key 3 times and found the solution?. Mine starts on the 3rd time only. I was wondering what part needed to be replaced.Thank you

Fuel pump. check ball is stuck allowing fuel to run back to the tank. Next time you try to start it, try this. Cycle KOEO 4 or 5 times before cranking it up. Starts right up then, you proved it.

Note that in addition to a problem with the check valve in the fuel pump, it could also be a problem with a leaking fuel pressure regulator or leaking injectors.

leaking injectors would be noticeable right? i know that another camaro i used to own the injectors would leak gas right above the engine. Super noticeable but that was the first visual i checked on this car first time i got it. fuel pressure regulator i will check that out

Leaking fuel pump check ball only leaves you with a symptom of long cranking.
Leaking injectors will cause poor running, black smoke and oil that smells of fuel. Eventually diluting the oil to the point of the internals being destroyed. Or washing the cylinder walls and galling the cylinder. Basically the same for a leaking FPR.

The fuel pressure regulator can "leak" into the return line, if the spring does not close the valve off fully. That's why one "test" for FPR leaks is to close off the return line. An injector leak does not have to be large to cause rapid loss of pressure, because the liquid is incompressible.
