No start 96 sunfire. no fire or pulse to the injectors. data port does not work. replaced computer and control module plus the crank sensor.

does it have spark ?
No Start No injector pulse shorted injector part 1

GM Bypass Ignition System Operation part 1

If you watch any of these ,watch the last one .Ignition control module can cause no injector pulse but still have spark

Why don't you take it to a ASE citified repair shop instead of buying parts you don't need ! Are any lights lit on the dash SECRUITY or flashing lights Did you hook up a scan tool ? An up grade - professional one an check for codes in all the vehicle computers . Most vehicle have ten or so , an a problem in anyone can cause a no start problem ! If your vehicle has Air bags , antilock brakes , anti-theft system , BCM - body control module , PCM -engine controller , remote door unlocks etc... these are all control modules . They all communicate on a serial data bus, an all it takes is one bring down the whole system ! Google CAN - controller area network , class 2 data bus , Chrysler CCD bus > The fuel pump has nothing to do with the injectors firing ! The engine computer does that ! An when you change a PCM / ECM it needs to be programmed , the dealer is most usually the only one who can do that ! Codes set in other modules other then the engine computer don't turn on the check engine light ! Most of the time your will have codes stored in other modules you won't even know it !

Crank sensor has to be bad,or the ignition module.Remove the ignition module and have it checked at the parts store.If it checks bad,replace it,if it checks good replace the cranksensor.The cam sensor,cranksesor,and the control module control injector pulse,and coil spark.I would point more to the ignition module.But I have known the crankshaft sensor to do this also.I hope this was helpful,if so,let us know,thanks,and good luck.

You are jumping to conclusions. Slow down.
No spark AND no injector pulse indicates none of the desired outputs were triggered. The ignition module makes spark when it receives a crankshaft position sensor signal, and then transfers control of that spark to the computer after it starts. The module takes its crank sensor signal and generates an RPM count that it forwards to the PCM(main computer) which is used for triggering the injectors and controlling timing. SO, if you had a bad crank sensor OR a bad ignition module, you could lose both spark AND fuel. a coil would not disable injector pulse. modules RARELY fail in a manner that disables RPM reference to the computer causing it to not fire the injectors...At this point, I would TEST the crank sensor as the next step. If its easier, 1 of the wires on the module goes directly there so you can test the crank sensor at the module.

Check for injector pulse at the plug going into the intake. Front of intake, drivers side.

could be, i think i replaced every thing else in the car, so why not give that a go

Replace ignition module. Engine computer is related only to the fuel injectors. Spark is only controlled by ignition module. Make sure that you replaced the prom chip inside the computer when you did your switch as well.

WOW a 94 with 46K on it thats rare. Your computer may be bad it sends the pulse to the injector.

injector pulse is just controlled by the ecm or computer as some would say,u said u replaced wires? did u have a fire or melt wires? ecm is known to go bad on these,had a few of these trucks back in the day.
