90 Z cranks but will not start
I drove it to work, would not start to go home. Got a new battery, still cranks but will not turn over. Any ideas?

Why a new battery? the starter turns the engine over but engine does not fire? Check INJ1 fuse. Sent from my iPhone using ZR-1 Net Registry

Yes. Battery was low, thought it did not have enough amps. I checked the fuse, it looked ok. Fuel pump was my next guess. Roll start would not work then, correct?

This is confusing. The starter spins the engine or not? I think you're saying the engine spins but does not start. Quick check is to spray starting fluid in the throttle body and crank the engine. If it fires and stops, you have a fuel problem. If it doesn't fire, you have an ignition problem. |

Re: 90 Z cranks but will not start
Follow the FSM diagnostic tree to figure this out. Otherwise it’s just a shot in the dark. There are multitude of things that could cause this.

Re: 90 Z cranks but will not start
Thanks for the info. Starter fluid started the car, but did not keep it running. Guess I’m looking at a fuel problem.

Re: 90 Z cranks but will not start
Now you can start going down the Chart A-7 posted above.
Have you checked the fuel pressure with a gauge? |

Re: 90 Z cranks but will not start
No. I bought a couple of the suggested fuel pumps and am sending to the local Vette mechanic to let him run the diagnostics. Would love to say I’m a DIY guy, but I don’t have that equipment. Or a garage, after the divorce. But, I still have my Z, so that’s something.
