Do I need to remove / lower the gas tank to replace the fuel pump on a H2 ?
I cannot see any access panel from inside cabin floor. the please help..

 

Yes you have to drop the tank. I paid to have mine done as it went out in Februray with a full tank. There was no way I was gonna do that job at home in the cold with a full tank. At a dealer expect to pay roughly $900 to have it all done.

 

You can do it yourself though.... the hardest part is dropping the Tank, like Eric stated. I piece of plywood, a ratchet strap, and a floorjack makes that MUCH easier.

The next hardest part is the retaining ring. I suggest a hammer and a brass drift to tap it into freedom.

The pump is around $400ish... and comes complete.


Just for the sake of curiousity, why are you replacing it? for performance or failure?

 

My fuel pump went on my 03 and it was $600.00 for the fuel pump and another $600.00 to have it installed and a new fuel filter put on the H-2. Total was just over $1200.00 after tax and all the other charges.

 

That's a huge ripoff....

I was wrong... the pump is only a little over $300 now... for an OEM pump...

yea 1200 is a big rip off. If you can try to do it at home.

 

Thanks everyone for your advise,
My Mechanic got the engine started today by connecting 12volts directly to the original fuel pump from a separate battery.
The engine ran smoothly and check light went out.

Does anyone have some ideas what to do now ??

Im thinking a broken wire on the fuel electrical harness somewhere or a bad FPCM, but Im not sure the engine would run if the FPCM was stuffed, seems strange.

 

Just for future reference, my lines rotted off the top of the sending unit. I ordered a new complete unit from ebay for 150 bucks. Also got a new retaining ring from GM for 10 bucks or so. Took a couple hours, but it wasn't a huge job. Just made sure the tank was near empty when I dropped it, and then completely emptied it before putting it back up.

As for your problem, I would just grab some wiring diagrams and start tracing wires. Good luck!

 

He needs to check and see if there is a power and ground to the fuel pump. I would suggest that the ground to the pump is bad, maybe a fuel pump relay. It could still just have a fuel pump that is worn out.

 

I have a fuel leak, dripping from the bottom of the tank. If this is a line or sensor, how many hours labor to drop the tank and repair a line, then finish?? Any feedback. I would assume this job should be no more then a couple hours
