Wont start. it has injector pulse but no spark


is there power and ground to the coils?

If there is injector pulse than the crank sensor has to be good. Injector pulse and spark are both calculated off from the signal from the crank sensor.

Checking for power and ground to the coils is a good place to start. If that checks out than either there is a wiring issue in between the PCM and the coils or possible the PCM has failed.

My van wont start no fuel or spark ?


Sounds like it could be the ignition module in the distributor. You have a throttle body instead of a carb. The injectors get a ground signal from the engine computer when they are supposed to open. The ignition module takes a signal from the pickup coil in the bottom of the distributor and decides when to fire the plugs and also the injectors.
If the injectors and the coil has power, it could be the module or the pickup coil.

I would start by checking to see if the signal is being pulsed to the coil and/or the injector. If those are good, check the compression.

1996 buick park ave, wont start, has spark but no voltage at injectors...


Spark indicates crank sensor, ignition coils and modules-ok
no voltage at injectors; should be 12v in each of the injector wires (not the black one) with key on engine off. Voltage provided to injectors comes from injector driver circuit inside PCM, and pulses ground signals to open and close injectors.

1996 Jeep Grand Cherokee No Start


I would be thinking that there is a good chance that you need to be checking out replacing the computer, if you aren't getting any communication with the proper scan tool then the computer isn't communicating with anything in the vehicle...... I would have guessed first off that the ignition control module might be bad but that is obviously part of the computer also, I would be looking in that direction.

Car has no spark or injector pulse(new ecm,crank sensor)


Check the fuse for the injectors, some vehicles have the injectors and coil running on the same circut, at the same time check the fuse for the ignition.

1995 DODGE RAM B1500 NO START


You need to use a LED type test light for the injectors or a Bosch style Noid light for the injector. To test the cam/crank sensor signal you either need a scanner to read them or a lab scope to show you a signal. The pickup plate in the dist handles the injector timing, the crank sensor provides a RPM signal. They both feed the computer information for ignition timing. Good fuel pressure, injector activity(Noid), and good spark out of the coil. The coil is what I replace the most of.
