a friend of mine has a 95 f150 4x4 5.8 e4od. and the fuel pumps will not come on. it has a new idnition modual all new relays i checked power at tank selector and inurtia switch n i get nothing. any ideas we are stumped

 

Is there power at the fuel pump relay power in? At control power?

 

thats one i havent checked yet but if not any other sugestions

 

The fuel pump relay is what turns the pumps on. If it's not working, they won't.

 

weve already replaced it 4 times cant have 4 bad relays the maxi fuse was good to but we changed it just in case

 

Doesn't matter how good the relay is if it isn't getting power.
There should be 12v at pin 87 and 12v at pin 86 when you first switch it on.

 

ok i will check it tomarrow if i dont what would you suggest

 

You just keep working backwards up the line looking for the last place that has power.
