I've got a 90 e 150 with a 5.0 why do I have no power to my fuel injectors

Asked by Aug 21, 2015 at 06:04 PM about the 1990 Ford E-150

Question type: Maintenance & Repair

1 Answer


The power comes from the OB computer and unless the engine is cranking or running you may not see it ... that power is a high frequency pulse but a good digital meter should see a low voltage. I don't think the anti-theft came out then so it may be a fault in the key sw circuit ... some injector circuits do have a fuse... Good luck
