94 olds will not start

[jocro]

cam sensor checks out ok.....crank sensor checks out ok....comp ok....ignition mod ok.......with key on I get injector pulse and RPM reading codes. The car got progessively worse and finally would not start. Any help greatly appreciated. JOE

Good spark on all 6 cylinders and injector pulse, when it won't start? Doe's the scanner read cranking rpms when it won't start? Injector pulse is not present with key on that is 12v only, pulse should occur on cranking.

That is part of my problem........not running..key on I get the pulse reading and the RPM reading......not cranking

You mean a noid lite plugged into an injector connector flashes with just the key on and not cranking the engine?

comp swapped out........still getting false readings on scanner telling me that engine is running..............yes to the noid light and not cranking...His next move is to check wiring harness. JOE

turned out to be crank sensor...............thanks for all the help JOE
