Ford Repair Questions? Ask a Mechanic for Answers ASAP
What are we trying to diagnose? Cranks but won't start? or no fuel pressure at the rail?
Sorry, but I'm confused; are you saying the engine won't start even if you jump the fuel pump? Are you checking fuel pressure with a tester connected to the rail? Have you made sure there is compression, spark and injector pulse and the only cause of the no-start is lack of fuel pressure?
Well, as it is, by the starting fluid test we know compression and spark are good. What we still don't know is whether or not the pumps can deliver the 35-45 psi fuel pressure the injectors require, or whether or not those injectors are being pulsed open by the computer.
So here is what I would do; I'd go to the parts store and buy a Noid light (less than $15) to check for injector pulse and I would also borrow a fuel pressure tester to check what kind of pressure is going to be available at the rail once I jumper both fuel pumps - or just borrow the fuel pressure tester and gamble on the injector pulse.
Or, you can gamble on both the fuel pumps being good and the injectors being pulsed and just repair the fuel pump circuit.
It's up to you, I'm on your side and will help you with whatever you choose to do.
