Hi, Chris, Don here, I am having a problem getting electrics to the fuel pump
on my 1990 Jeep Cherokee. I have replaced ECU, all the relays test good, if I hotwire pump, it works fine but just not getting electrics under normal circumstances.
JA: How many miles are on the car? Has the car been starting normally?
Customer: 149,000+ and it won't start, fuel pump isn't running when I turn on ignition and/or crank starter.
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: Yes. I have replaced ECU (foolishly probably) and checked all relays, they check good. I've checked wiring from fuel pump relay to pump, it's good.
JA: Anything else you think the mechanic should know?
Customer: Not that I can think of.
