No Start Engine Cranks

[fastdon3]

I have no injector post, but engine cranks. I have spark and I have fuel. I checked cam sensor votage which was set at 7.02 volts. Could crank system be the problem? Where do I check next?

If you have no injector pulse I would check the cam sensor.

Yes and check also the injector fuse and the injector harness connector.

Pull your plugs to make sure your getting fuel into the cylinders. My dads car was doing the same thing, had fuel pressure, spark, etc.......... but it would not fire. The injectors where locked up........... MSD 50's. And yes, Im not joking. Swapped injectors and the car fired right up. Hope this isnt your problem.

Go to Vortex Turbo Buick Performance & look under the No Start tree. Lots of good info.

+1. You cant have spark without pulse first since the cam sensor is responsible for finding the #1 on startup before it will fire spark.

If you follow the GM chart you will find it. I had an intermittent open circuit on cam sensor pin B that was a bitch to find a few weeks ago.
