so im driving then blaaaa engine shuts off. so i turn off the key and now the pump isnt priming, i was bouncing around alot so im thinking maybe inertia swtich, but im not sure its an 87 f250 with a straight six, the pump wont prime, and i checked the fuses

Most fords have an inertia switch for the fuel pump as well usually located in the passenger side kick panel.

eec regulator j roc? ill give that a shot. but will that make the pump not prime at all? and how do i reset the inertia switch just in case?

If it has the inertia switch it is just like a big circut breaker and has a reset button on it just depress the button and good to go

Could also be the fuel pump relay. It takes quite a impact to trip the inertia switch.

it was bouncing alot, is there any way to test the regulator thing or the fuel pump relay?

yup u should here it prime...

if it aint priming then u dont need to look at you regulator yet....

sounds like u lost power to the pump.. check for power there with key on

check for pressure at the shrader valve if u do not have pressure then your system is not priming from the tank... or your fuel reg is pooched allowing pressure loss via return line.

To test the relay. Pull the rely should be located at the fuse panel under the hood. Hook up a 12V to the connector marked 86 and connector 30 ground connector 85 relay should then click. If you have a test light put it on connector 87 it should have power. If it doesn't the relay is pooched. Hope this helps.

Id just bust out the test light and check the wires at or near the tank, then just work your way from there.

if the regulator goes the pump wont get power, same prob on my truck, its the cheapest part to change
