im working on my nephews 88 dodge ram 150 4x4,it has the 318 TBI motor,automatic,my question is i cant get power to the fuel pump,so im thinking fuel pump relay,where is the fuel pump relay?,where can i find a wiring schematic for this truck online?,any help would be appreciated.

 

on the drivers side inner fender

 

The fuel pump relay is the front relay on the fender. Be aware that the second relay is the ASD relay and can also cut power to the fuel pump.

 

what does ASD stand for?

 

ASD=Automatic Shutdown Relay

 

shes up and running now,it was the fuel pump relay
