Fuel pump relay location

I had the same problem. It was hard to find as the resistor worked fine while cold, but freaked out when hot causing the fuel pump to shut down. It was hard to find due to the temperature breakdown. Bypassed the resistor and it runs fine.

Thank you so much John for this even 5 years later it helped me, I tried hot wiring with fuses and a external relay and I still couldn't get it right, I found this article pulled out that mess of wire, connected original connections to fuel pump. I then removed that ballast resistor and connected those 2 wires. Turned over and continued running. After months of replacing part after part you helped me with a single paragraph and I thank you.

I have a 1998 Jeep Grand Cherokee Limited with a 360, 5.9 litre. I just recently replaced the starter. A week later, to the day, I break down at the store. It cranks and is getting spark and power. So I had it towed to my garage, I automatically assume it's the fuel pump. I do a few trial by eliminations.1. I checked to see if I was getting power to the fuel pump with the key on, but nothing.2. I checked the fuel pressure, but there's hardly znything there just a faint smell.3. I check ALL relays and fuses, but they seem fine. 4. I hook a PCM to the jeep and get the error code 1282( Fuel Pump Relay Control Circuit ). SO NOW I don't know where and what to DO. I'm thinking it's the ECM and was wondering if I can find and repair the relay in the computer? Or do I just need a whole new ECM? I was Hoping I could get some GOOD news and there might be something else I can try? I would HIGHLY appreciate ANY and/or EVERY advise on what to do next, b/c I'm in dier straits! Please Send Help!

For some reason, we don't always hear the fuel pump kick in when the ignition is engaged on our 93 jeep grand cherokee laredo. When it's cold and we don't hear the fuel pump, it won't start until we mess with turning the key off and on until we hear the fuel pump. I've changed numberous things trying to fix this problem and it's hard to really know if the problem is solved because we have to wait until in the morning and see how it starts. So far I've changed the following: Fuel pump, Fuel pump relay, ASD, Fuel pressure regulator, Fuel filter, Ignition switch and I think that's it. Not sure what to change next so I need some help! It used to start perfectly and I suspected the fuel pump, which I changed first. Now I've changed everything I can think of. Any advice? Thanks!

Yes, there is no problems with the ignition spark or injectors pulsing. The only time the problem is present is when the jeep is cold or has sat for a few hours at a time. It runs perfect after starting. The fuel pump has started sounding "different" today though. I have a feeling that the new fuel pump I put on is actually bad too. I always hear the relays clicking and everything when I turn the key to engage the fuel pump but I dont always hear the fuel pump kick in and it won't start when I don't hear it unless I've just shut it off and the lines are still primed. The problem seems to be getting worse. Another bad fuel pump maybe? Is that common? Thanks!

I got a 1997 jeep cherokee, I get no power to fuel pump at all, I checked the relay and it works, but when I test at fuel pump I get no power, there is power going to fuel pump relay, but no power comeing out of it, can you help me?

My jeep would backfire and almost stall, but I could turn the ignition switch off, then on quickly, and it would stop backfiring and run a little better for a mile or so, then the same thing again. Now the fuel pump will not work while in the tank. If I take it out and run a jumper from the battery, the pump motor will run. I am only getting 5.6v to the pump wiring harness plug when I turn on the ignition. I can't even find the pump relay. The Haynes manual says the system has two ballast resistors, but the auto parts stores say they don't show one. Frustrated! Got any ides? Thanks so much for reading this.

I checked the current at the green/red tracer on the fuel pump harness with the switch turned on. I got 5.6 volts, that is not correct, is it? Thanks again, esp, the quick response. Flatspin

I had replaced all my relays under the hood and finally got power back to everything because I had pulled way to much power from my kc lights. It blew a few different things I didnt have spark or any voltage at resistor in fuel circuit. After replacing the relays I have power back everywhere. But the resistor is only reading about 2 volts. So I at least got some power bak at the resistor but Not enough. Its stays at around 2 either at the resistor or at the pump and stays the same while cranking. The voltage doesnt change while cranking either.
Why am I not getting full volts back for the fuel system?

The resistor is on the front fender well.

My 1996 Jeep Cherokee Sport will not start. I checked the fuel pressure and there wasn't any. I checked for the humm in the gas tank and there wasn't any. I found the relay in the Power Distr. Box and measured the voltage across the coil of the relay and I would see it jump to 12V when the key was turned to the run position but instantly fall to 6.5V, which I believe is not enough to pull in the relay. From the Chilton book I have it looks like the low side of the coil is connected to the ECU so I'm thinking I have a problem with the ECU. Any suggestions.
