My van cranks over but will not fire.
if I spray starting fluid in throttle body it will start.
my fuel pump is working and I have a lot of fuel pressure up to throttle body, and have fuel returning to the tank. I tested the injector connector and have no power. I already changed the ignition module and that didnt work. Where do I go from here?

Turn on the ignition key and see if the check engine light comes on. It should. If it does then check for 12v at the plug on the injector and see if one has power with the key on. Let us know

The computer might not be getting an ignition reference signal from the distributor-Injector not pulsing check the fuse below and could also be the computer injector driver on the dark blue wire-
