HEY ALL , I HAVE A 97 EB EXPO AND JUST SHUT OFF ON ME AND DIDNT WANT TO START AFTER. COULD BE FUEL PUMP, SO I CHANGED IT, CRANKS BUT WONT START, NO VLTAGE GETTING TO PUMP, FUSE ARE GOOD , RELAY GOOD , NOW I DONT KNOW WHAT TO DO. ANY IDEAS PLEASE .

 

Check the fuel pump shut-off switch located in the passenger's foot well by the kick panel.
Check the fuel pump relay in the power distribution box under the hood, relay 301 on a 2001, don't know if it is the same on yours. Also check for a loose contact to the relay.

 

Check fuses F19, F24, & F30 under the hood along with the PCM Power and Fuel Pump relays, all under the hood. Keep in mind that the fuel pump is turned on by the PCM, so it is necessary that the PCM is properly powered and operating before the pump can be turned on. If the MIL comes on when the ignition is switched to ON, the PCM is at least receiving power.

...and fix your CAPS LOCK key, it appears to be stuck in the ON position.

 

Thanks guys ill look into that today but i already checkd the fuel reset button. when its up im getting 11.7 in voltage to the pump when its down i get 0.24 volts

 

ok guys i checked all fuses and relays and all check out fine but where is the PCM i cant seem to locate it

 

Under the dash, passenger side, remove the kick panel and you can't miss it.

 

Regarding the fuel pump, you just assumed it was the pump without really diagnosing the problem. Your old pump could've been good and the whole problem was just a loss of power to the pump the whole time.

 

Yes i know but i have two expos and the same thing happen to that one so its safe to say i assumed. but i wont have to worry about changing the fuel pump again its brand new

 

OK so its been about a week and i still cant get my truck to start cuz i cant figure out why im getting 0.26 volts to the fuel pump, i checked the inertia switch(fuel reset) and its fine . im not sure what to do now, anymore ideas folks ?
