If fuel is put in the carburetor it starts. Got fuel pressure. Put a test light, got power to the injector.

Hello,

This could be a problem with your vehicle's Crankshaft Position Sensor (CKP). Your vehicle uses the signal from the CKP to determine the rotational speed of the crankshaft. It uses this information for engine speed and for misfire monitoring. If this sensor or it's associated wiring fails, your vehicle's Power-train Control Module (PCM) will not recognize the engine is turning over and will not send spark to the plugs. I have included a few links for you to go to below:

I have also included some diagrams for your vehicle's CKP in the diagrams down below for you as well. Please go through these guides and get back to us with what you are able to find out please.

Thanks,
Alex
