- IM JUST SHOWING WHAT TO LOOK FOR IF YOUR FUEL PUMP IS NOT WORKING. IN THIS CASE MY FUEL PUMP WAS FINE AND THE PROBLEM WAS I DIDNT HAVE POWER GOING TO THE FUEL PUMP FUSE AND RELAY AND I FOUND THE FUSIBLE LINK HAD BEEN RUBBED RAW ON THE CROSS MEMBER AND BLEW THE FUSE IN THE FUSIBLE LINK SO I REPAIRE THAT AND THE POWER WAS RESTORED TO THE FUEL PUMP RELAY AND FUSE AND FUEL PUMP WORKED FINE AGAIN.
GM RELAYS HAVE POWER (BATTERY VOLTAGE) ON 2 OF THE PINS. ON THE FP RELAY YOU HAVE TO TURN THE KEY TO THE ON POSITION TO HAVE POWER AT ONE OF THE PINS AND IT WILL HAVE POWER FOR 2 SECONDS AND GO OFF BUT THE OTHER ONE HAS POWER ALL THE TIME AND THIS RELAY DIDNT HAVE EITHER SO ALWAYS CHECK THAT FIRST AND ALSO CHECK FOR A GROUND.
THE ONLY OTHER THING ON THAT COULD BREAK THE CIRCUIT ON THIS VEHICLE IS THE OIL PRESSURE SWITCH. ITS IN THE FP CIRCUIT TO PROVIDE POWER TO THE FP IF THE RELAY GOES BAD AND IT HAS TO HAVE OVER 4 PSI OR IT WILL OPEN THE FP CICUIT. ALSO I DID DROP THE GAS TANK AND CHECK FOR POWER AT THE FUEL PUMP CONNECTOR AND THERE WAS NO POWER THERE SO I KNEW I HAD A OPEN CIRCUIT BETWEEN THE BATTERY AND THE FUEL PUMP FUSE OR THE ECM AND THATS WHEN I FOUND THE FUSIBLE LINK WAS DAMAGED AND RAW WIRE EXPOSED.
tough problem , it's good
the new pump is inn . My
3.1 is cutting out during
driving . No error code set
I have this exact same vehicle and am having similar difficulties. I now have another thing to check thanks to this video. I'd rather repair a link than drop the tank etc... Thanks, either way.
I just wanted to show what to look for if your fuel pump is not working and I couldn't find a video on this specific vehicle or problem so I decided I would make a quick video
Awesome. I am having the same problem. No power to the fuel pump.
Where are the fuses on this car?
are they connect to the starter?
thank you.
where is the fuel pump? is it located in the gas tank?
