99 trans am problem. need ideas!! Hey guys. Been having a weird problem with my t/a and wanted to see if you guys have any ideas as to what it could be.
The problem: the car cranks fine. But doesnt turn over everytime. Sometimes itll crank for 3 or so seconds and then turn over. Other times I let off the ignition and try again and it starts right away.. there is no check engine light, no loss of power and once the car is started it runs 100% fine.
I got my battery and alternator checked and theyre fine. Spark plugs and wires were replaced less than 10k ago. And same with fuel filter.
any ideas would be GREATLY appreciated!!

Maybe the fuel pump is on its way out. Thats what it sounds like to me.
I would suggest the Coil packs as well but you would think that would just cause a misfire if one of those were gone.
I'm used to Distributor ignition. Do the LS1s have an ignition control module and or ignition coil? If they do, check those as well.

It's probably not the lack of pressure when it's running but rather leak down. Try cycling the ignition three times before trying to crank (letting the pump run for 5 sec or so) and see if it won't crank every time. If so replace the pump and you will be good.

Would it even be worth buying a fuel pressure tester? Or should I just go ahead and replace it?
