Ford Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I’m Ron and I can help you.I have been in this business since 1975 and also teach automotive repair. I am confident we can resolve your problem together. Please understand that I don't know your skill level. I can't see, smell, hear, or touch the vehicle either, so it may take a few replies to get to satisfactory results. Please be patient!I also try to give all of the information you may need, expecting a “positive rating” in return. I will also continue assisting you after you have rated me, if necessary. If there is any reason I cannot get a positive rating, please let me know why “in advance”, so I can go another direction for you. I am sorry you’re having this problem; I’ll help you through it.
The power to the pump comes via the computer. First check all your wiring, fuses and relays.
I would still check the pressure and volume with a gauge so we can move on to other options such as exhaust restrictions, bad MAF sensor etc. If you have scan tool data, that sure would be helpful at this point and any possible codes that are in the computer.
We need to be accurate in our reading and tools we use, otherwise we're just wasting each other's time.
