i have a 1994 trooper 3.2

the fuel pump isnt turning on at all so figured i checked the easy first fuses all are fine checked relays seem to click i dont have a tool to really test them i swapped them around still same result ... so i replaced the pump still nothing ive see people jump the relay i just dont know which ones i could jump dont have a diagram for it

i chased wires from the back alll the way up front ....there is a mention that there is a ecm fues on the ecm it self? i dont know where that is if someone could help me out that be great thank you

 

Have you fixed it yet mate? I'm having a similar issue with mine and following the schematic it seems that if the diode in the alternator is u/s the fuel pump relay wont get signal to switch the relay. The air con blower will also stop. If you pull the plug off the back of the alternator the fuel pump fires up
