I have a 83 944 than runs only in start position. when switch is moved to run the engine stalls. 30 psi fuel pressure, good spark, speed ,ref sensors, ign switch, temp sensor and fpr replaced. noid light on injector is very bright in start position but dim in run position. With ign on and all injectors unplugged it has battery voltage on hot side of injector and 10.5 volts on the neg or pulse side. Thanks for any help you can give.

Thanks but thats not the problem. Has no vacuum leak, afm and temp sensor are ok. It will idle if feed propane through the intake port. Seems to be fuel starved. With key on engine off 10.5 volts at neg or pulse side of injector harness with all injectors unplugged and very weak pulse signal seems odd. Thanks all suggestions are appreciated.

The ignition switches tend to go bad. You can probably keep the lock core and just replace the electrical portion.

He said he already replaced the ignition switch.
