Hey guys as stated I have an 88 f-150 that will not start I have checked fuses and put new relays in and still can not get any power to the main fuel pump...I have a battery charger on it and it will turn over fine...I have no power to the emergency fuel shut off wiring harness either...any help would be greatly appreciated!! We are trying to get this pickup running to irrigate as a couple of our other pickups went down also....we really don't know where else to go!!!

 

check ground wires...

 

if your refering the ground off of the the battery then i have done that...I can crank the pickup all day long but i just cant hear the fuel pump kick on i unplugged the wiring harness and am getting no power down to it...

 

you did state that you have replaced relays, are you getting power to the relays?

 

we have power to the relays but not out...we also jumped a ground wire somewhere (i have a buddy helping me while im at work) and said he can get the pumps to start working. It will still not start no fire and the injectors are not pulsing...he said its leading him to the ecm?? i ordered one today we will see what happens
