I have a 91 Ford Escort GT with a 1.8L dual cam, 5 Speeds standart.
When you first turn the key on, the fuel pump is supposed to run for a few seconds so as to prime the system. Mine won't work as advertise.
I have checked the fuel pump itself and it works just fine. I have also put in a different fuel pump unit to compare, and the same thing happened.
I have replaced the fuel relay in the main fuse box, and still it will not work.
I have replaced the Inertia Fuel Cut Off Switch, and still nothing.
I have replaced the PCM/ECU and still nothing.
(BP09 1888 1B) I am also told that I can use the 1A, 1D and 1R as re[placement for the 1B.
I went into the Diagnostic box in the engine compartment, and grounded the Fuel Pump and that turns it on no problem.
What am I missing here?
I am learning as I go, therefore, if you have some advise using acronims, please point out the where abouts of those items. My wife would be most thankful for any help pointing out the real problem here, aside form me being her mechanic.
Thank you.
