No Power To Fuel Pump, 2000 Windstar
My problem started as an intermittent start, but progressively got worse and is now a no start condition. When I turn the key I do not hear the fuel pump turn on.
So far I have replaced the battery, fuel filter, fuel pump fuse twice, fuel pump relay and....Fuel Pump (ouch I know). I was hoping changing the fuel pump assembly would eliminate my problem but, it didn't.
Now I am learning how to use a multimeter. I have 12V at the fuel pump fuse and at the relay. My next move is to check the inertia switch. If I have power there, what does this tell me?
I was also going to try checking power at the fuel pump. The wiring harness extends beyond the tank, so I wont have to drop it again.
I am wondering if its a bad ground. Another thread suggested spicing into the fuel pump ground and connecting to a known good ground.
If I have power, a good ground, and a new fuel pump, what else is there?
And what is this PCM thing I have read so much about?
I appreciate any help you can provide. Thank You.
