Hello Everyone,

My Camaro finally started after sitting for over 3+ years. I changed the fuel pump to a walbro, change the fuel filter with a K&N, changed the fuel pressure regulator, replaced the southbay injectors with a new set. The PSI at the rail is staying at 43psi. Replaced the battery yesterday. The car finally turned over for about 10mins and then it died and It can't turn over again? Next thing is, I accidentally broke the heater valve vacuum line and I am gonna fix that today.

check battery state of charge if you cranked for 10 minutes. Good way to smoke a starter.

I wonder if the OP means, "The car finally STARTED and ran, for about 10 mins (minutes) and then it died and it can't start again" (but cranks)? That sound about right OP? It helps when the right terminology is used.
"Turn over" refers to the starter motor "turning over" (or cranking) the crank shaft.

Otherwise, if the OP actually ground on the starter motor for a whopping 10 minutes...I'd say the next step would be to charge the battery and buy a new starter motor.

At this point, if it cranks but doesn't fire or start, I'd go back to the basics and check for spark and fuel.

It cranks but it doesn't fire. That's the correct terminology. New battery was put in yesterday and the starter is still good and cranks fine, just won't fire. What's the next step in troubleshooting?

Injector pulse and spark ? I’m assuming this is efi with that much fuel pressure?

test spark first..if no spark check ignition component condition - distributor cap, rotor, ignition coil, get ignition control module tested etc

It probably didn't lose compression in the middle if running. If it has spark, then it's pretty likely that the ICM is fine.

After some parts swapping, which I have to do anyways. I changed the spark plugs, changed the spark plug wire (taylor custom wires) replaced the ICM and pickup for my MSD distributor it starts right up. It was the MSD ICM and pickup.
