Thread: Having a problem with a LS1

Rent or borrow a good ODBCII scanner / engine diagnostics. Hook it up and run it while driving. It's best to have someone drive as the other is monitoring the scanner. It will tell you a ton of what is going on with the car.

Yes, fuel pressure while running should be well above 30 PSI - if not, check filter, pump, regulator for problems. Your problem does sound like fuel pressure.

I have a 90 corvette that sits more than now than it use to that started idling
rough. once you gave it some gas didn't seem to be any problems . I had three
injectors that were not working at all. they make a tool now my buddy has one
all you do is have the thing running and point it to each injector and it will tell you if its working. He told me need to drive it to keep things working.
good luck
