I have a 92 Camaro with the 3.1 that when. When after sitting for a while I go to start it, it starts up quick the dies immediately. The it'll crank for 10-15 seconds until it starts again the will run and idle perfectly. And if I cut it off after it's been running, it'll start right up like normal. It only does this if it's been sitting for an hour or more. And it acts the same exact way every time without fail. It's also coding also and the light never comes off. It's a code 32 which is:

32.Fault in barometric pressure sensor circuit OR Fault in exhaust gas recirculation valve diagnostic switch OR Fault in electronic vacuum regulator valve

And one thing I noticed is right before it does start after cranking for that period the oil pressure shoots up from 0 to 3/4 of the gauge.

And another thing is, whether it's related or not to that problem or not, is that when turning a somewhat quicker than normal corner, it'll die in mid turn then I'm cranking and cranking again in neutral until it starts again

If anyone has any suggestions then please let me know

 

I would start by checking all your vacuum lines for cracks or looseness. If all the vacuum lines are good, check the map sensor, egr valve and egr regulator vacuum valve.

 

Code 32 on that car is an EGR failure. Which is strange as the ECM only tests the EGR valve during coast down at highway speeds. May want to double check the code number. Note that the test may not be running properly due to another sensor failure.

The EGR test uses coolant temperature, TPS, MAP, MPH and RPM.

As for the startup issue, sounds like the fuel pump relay isn't running the pump. The pump is running from the oil pressure (backup) switch.
