I have an 06' F-150. Last monday went to start and wouldnt crank over. I have since replaced FPDM, a weak fuel pump, checked Fuel Inertia Switch and now that they are all replaced when I check codes it says "no data available". Pump will not come on. Fuses have been checked. I have traced this problem to everything I can think of. If my ECM is fried, why would it have worked fine before replacing FPDM? I am at a dead end. Mechanic is at a dead end. Please help.

 

ECM is fine. Had it checked, and nothing is wrong with it. Im going nuts trying to fix this. I dont know what else I can check.

 

So it is turning over and firing just no Fuel? When you say that the fuel pump is not turning on I assume that you definitely do not have any pressure at the rail. Is there a chance that one of the components that you replaced is faulty?

 

Yes. Checked both pump and module. Both work according to mechanic.

 

If I spray it with starter fluid it will start right up and run great. But it dies due to not getting ant fuel. No codes are being thrown. I have tried fuel inertia switch, fuses. I'm lost.

 

Have you checked power and ground at the pump itself ?

 

Ground at the pump was the problem. Thank you very much for this suggestion. You saved a possible heart attack. I now have my truck back and am extremely happy. Thanks again!!

 

Happy to help. And thanks for posting the fix ! I don't like loose ,dead threads . It could help someone else in the future .

 

Oh aint that the truth!
