Damn, he'* got me beat by 5K miles.

Glad to hear your up there with the big boys, fortunately yours is still running. Looks like I'm going to be pulling the tank out along with the fuel pump this weekend, and I'm not looking forward to the cold.

Wish me luck cause I'm not gonna be a happy camper.

Maybe you'd have better luck if you started rooting for the Flyers?


I had to drop the tank in my Blazer. It is tough work, but not impossible. Honestly, I'd look into having a shop do it to save yourself some frostbite.

Did you ever jumper the relay to see if the pump turns on?

It'* over for the leaf'* this year anyway, as for the relay, I tested them all and they work. As for dropping the tank it'* one thing to do it in the summer but here in TO. it'* about 12 Fahrenhiet today, and that'* during the day. I would have to tow it the shop. I priced out the pump at $112. Canadian and $10. for the filter. The pump retails for $141, guess the parts guy felt sorry for me. Not to happy with my Bonne lately.

Do yourself a favour and hug your Bonne tonight before you go to sleep, you won't regret it.

You can't just swap out the relay. If you remove the relay and then jumper the common to the energized side it should provide power to the pump and activative it.

If you do this and the pump works, then you may have a signal problem. Meaning the signal from the ECM is not getting to the relay.

If you do this and the pump doesn't work, it still could be that 12VDC is not getting to the relay and thus not carrying to the pump. You will need to check for 12VDC on the common of the relay.

Our cars are getting old and so is the wiring. I've found a couple of circuits which were bad, because a brittle wire broke in the harness.

12 is not a lot of little fahrenhiets.

I'm still at work. I have the schematic at home. I'll look it up for ya, and tell you the exact pinout which you need to check.

As far as the part, check out http://GMPARTSEXPRESS.com. I also have the Parts Manual at home I'll look that up as well.

Another note. If you are going through all the trouble of dropping the tank you may want to replace the fuel sending unit as well. I didn't and now my fuel gage is screwed up, but not enough to make me want to drop the tank again.

P.*. I hate Joe Carter.

Thanks for the reply KEOTOK, the problem I'm having is that there are a total of 9 relays of which I haven't isolated the fuel pump relay, also I don't know which terminals to jump. If I could find an easier way to get the car going I would try.... after all, there is no guarantee that replacing the fuel pump will get my up and going again. If you read my previous posts it explains the relays in more detail.

By the way when working upside down on a 15 year old car, 12 seems like alot of Farenhiets. And it'* good to know some still remember me and my Bonne problem.

After all this is said and done I need to get back to my guitar Amp problem......ya ya ...... it never ends........I wish i were rich............lol don't we all.

Alright here we go.

The Fuel pump relay is located in location "H". Which is on the right side, third one up from the fuses.

Check fuse 6 on the same panel. It'* on the bottom row second one from the left (20 Amps)

Pin 1 on that relay is the 12VDC when the car is in run (comes from fuse 6 above). Turn the key to start and use a voltmeter to see if 12volts is there.

Pin 4 goes to the pump. Jumper 1 and 4 together. You should get a pump running. The connector behind the battery bypasses this relay and goes right to the pump.

Pin 5 is the signal from the ECM. That should also be 12VDC (or maybe 5VDC the book is not specific) when the car is in run.

Pin 2 is ground for the coil.

What is what pin? That'* easy. The socket has 2 verticle sockets, and three horizontals. starting from the left is 1, 3, 4. 2 is on top and 5 is on the bottom.

Any voids in these pins means that a wire is broke or your ECM is broke.

I had trouble finding the part number in my book. I'll keep hunting.

Good luck. Let us know of the results.

try this. while someone tries to start the car, use a hammer to bang on the underneath side of the gas tank. sometimes this will shock the fuel pump into working.

be careful when doing this though. i just thought of you doing that, and just as the hammer hits, zoom out to reveal a big mushroom cloud. maybe a block of wood would be better.

have never had problems doing this in the 15 yrs as working as a auto tech.we do this at my job so we don't have to push big vans and trucks into the bays to work on them. also have many other friends that are techs that use the same technique to shock fuel pumps into working.
