Anybody have there fuel pump fuse pop, took off out of wash 11 (Glamis) and about 100 yards the Maverick felt like it lost power and just shut off. I tried to restart is to no avail towed it back to camp (by a RZR) only to find out about 1/2 later my fuel pump 5 amp fuse was blown, any ideas????

When I first got my Commander the 5 amp fuel pump fuse popped twice in about 3 hours. I spent several hours checking the fuel pump and going thru the wiring harness looking for a short. I was at Durham town for a rally race and after driving 14 hours to get there I just stuck a 10 amp and never looked back. That's been 3 years.

hmmm.....the Fule pump is on it's own circuit. If it blew the fuse, I would put a meter on it while it is off and see if you have a short to ground. Do you happen to have a fault code present?

P-CODE MODULE DESCRIPTION CAUSE ACTION

Code - P0231

Symptom - Fuel Pump circuit shorted to ground, or open circuit. Blown fuse, damaged or disconnected fuel pump, damaged circuit wires, damaged connectors or damaged ECM output pins.

Corrective Action - Check fuse, Measure voltage between harness connector FP-B and ground (Expected value: 11 to 13 volts). Measure resistance on the fuel pump connector between terminals B and C (Expected value: < 2 ohms) Measure resistance from harness connector: ECMB-M1 to FP-C (Expected value: < 2 ohms) Measure voltage between harness connector FP-C and ground (Expected value: 0 volts)


Code - P0232

Symptom - Fuel Pump circuit shorted to battery +. Damaged fuel pump, damaged circuit wires, damaged connectors or damaged ECM output pins.

Corrective Action - Check fuse. Measure voltage between harness connector FP-B and ground (Expected value: 11 to 13 volts). Measure resistance on the fuel pump connector between terminals B and C (Expected value: < 2 ohms). Measure resistance from harness connector: ECMB-M1 to FP-C (Expected value: < 2 ohms). Measure voltage between harness connector FP-C and ground (Expected value: 0 volts)

Yup, popped three of them. Did the bad thing and put a 10amp in. Zero problems and after talking with the lead tech of the dealer he said I would have zero issues running the bigger fuse. Haven't had a problem since and probably never will. I packed the fuse block full of dielectric grease when I did it.

Sounds like I'll be putting a 10 amp in tomorrow! I hate breaking down in the middle of nowhere!
I bought a pack of 100 assorted fuses on eBay for like $3 shipped and keep them in a little kit in my glove box as cheap insurance. I would venture to guess that the cause of the blown fuse is a poor connection. I would reseat all associated connections and ensure they are clean and in good condition and apply dielectric grease liberally prior to reconnecting them.

Good information I went thru the steps and all that came up was "NO Active Fault Code" Now I did already replace the fuse would the fault code show up even after I replace the fuse.

Most likely not. I think you would need to run a diagnostic on the BUDS to see any historical codes that were flagged. It sounds like a common issue so, I wouldn't be to concerned with it.
