I have a 1989 E-150 van. I bought a noid light, hooked it up to my fuel injector pigtail, and my fuel injectors aren't getting any signal. What would cause this, or what could I check?

 

I would start at the ignition module, take it and have it tested (autozone can test them), if the computer doesn't recieve signals indicating the plugs are firing it won't pulse the injectors.

 

I have had the ignition module tested (good). Replaced the engine computer. Replaced the eec and fuel pump relays....

 

There is a magnetic pickup sensor in the distributor, sound like it has gone bad, it passes signals to the computer to fire the spark plugs, and in turn fire the injectors. If that doesn't fix it then I'd start lookin at the wiring connectors, there is one on the passenger side I think that controls the injectors, we had it unplugged in my dad's van and it would not start. We plugged it in and she went vroom......

 

do basics first,spark,fuel pressure,pull codes(will give you a idea which way to go)will help replacing a lots of expensive parts needlessy.no injector drive signal could be ignition module or stator but guessing is never a good idea

 

I am getting no codes at all (000). The eec was replaced (no change). The module was checked (checked out good). The motor will fire up and run with starting fluild shot into the throttle body. If it was the stator-pickup wouldnt the there be no spark?

 

you should at least get pass a pass code(11) if you mean there is no codes outputed at all, you ara not testing right or mabye no power to pcm.or no pcm ground(mabye check pcm ground at bat.neg.)a 10gage? wire connects to negative bat cable close to post, and also grounds to body close by. can give more wiring help if necessary

 

10 gague wire on the neg side of the battery-Thank you Gary!!!!!!

 

hope that helps, let me know
