The 8th digit in the VIN is a W.

I appreciate you sending me that wiring PDF.

I have both a good multimeter and a 12v test light.

I plan to test at the prime wire and then again at the fuel pump connection to make sure I have power and ground before I do anything with the fuel pump. If both check good, then I'll go ahead and replace the pump.

I should be able to update on the progress later this afternoon/evening after I get over there and do the tests. I'll let you know what I find out.

Thanks!!

You are welcome.
It is in the mail. If you do not get it or cannot open or read it let me know.
Good Luck. MT

Re: 95 Jimmy SLE died while driving and now won't start

Great, Thanks!

I got it and printed it out. Looks good.

Quick question to make sure I'm reading this right.
The fuel pump is on a 20A fuse right? I just want to make sure before I go to Radio Shack to get the fuse holder and fuse to make that jumper wire.

Ah, another question, not about that PDF though.
I tried the other day to get to the relays in the glove box but couldn't get the cover off. I had pulled up on the two tabs on the bottom then tried pulling out on the cover but it wouldn't budge. Is there something I'm missing?

Thanks!!

The fuel pump should not pull over 10 amps.
But a 20 amp fuse or circuit breaker is good. The fuse is just for saftey in case of a short someplace.
I always us a circuit breaker to save on fuses but either one will work.
On the cover give it another try or there may be a hidden tab.
They do not make it easy.
Also check both sides of your fuel pump fuse for 12 volts.
Good luck MT

Re: 95 Jimmy SLE died while driving and now won't start

ah, a circuit breaker, thats a good idea. I'll see if Radio Shack has anything for a good price.

hmm... no they don't do they, make it easy that is. ok, I'll just try it again.

Thanks

ok, just so I'm clear on this one... I just take the ends of each probe and put them into each side of the fuse to check for the volts right?

Not unless you are checking ohms.
With a volt meter you ground the neg probe. And use the positive prove to check for voltage.
On a fuse check both sides with the positive probe for voltage.
And if all else fails read the instructions that came wit the volt/ohm meter.

One quick note here, a brass drift punch should be used to avoid any sparks!!

Good point, I'll have to find one.

AutoZone has a AC Delco pulsator in-stock for 20.99 If I don't have the pulsator and just the rubber tubing like you said, do I need to do anything?
The Bosch fuel pump doesn't use a pulsator, as it's not needed. Read the instructions that can with your Bosch pump.

Bosch style turbine pumps provide a steady stream of fuel as opposed to older georotor or roller-cell type fuel pumps that provide fuel in high speed pulses. Output from a turbine is smooth, consistent and high volume + pressure. The little black high pressure fuel line that came in the Bosch kit replaces the bulbous, brass and plastic press-fit pulsator unit.

Re: 95 Jimmy SLE died while driving and now won't start

ok, I'm trying to check for power at the pump as we speak. I checked the black wire and it looks good but no power on the gray wire like you guys are saying. There are three wires going to the pump... Black, Pink(ish) and Gray. I can't get any volts to read on the gray wire but I get a volt reading on the Pink wire. Is the Pink wire the one I'm supposed to be checking? What is the pink wire for? Please let me know asap because I'd like to get this part figured out tonight before we lose light.

Thanks

Re: 95 Jimmy SLE died while driving and now won't start

On the '95 there is a fuel pump test wire under the hood on the driverís side next to the fender, under the hood hinge. Itís a red wire that has a gray plastic cover on the end of it and it just hangs there next to the electrical junction box. Put a live 12 volt jumper wire to it and the fuel pump will run if it's not toast.

Have you tried the above??

Re: 95 Jimmy SLE died while driving and now won't start

yeah but nothing happened. Maybe I didn't have it in there all the way or have a good connection but nothing happened thats why I went to the connection at the fuel pump under the car to make sure it was getting power. But thats where I got confused because everyone is saying the gray wire is power but the gray wire isn't showing power. The pink wire is however getting volts and noone said anything about a pinkish colored wire being there. Just like in the pictures you posted earlier, that purple/pink (or whatever color it is) color wire.

Thanks

Stand by a couple minutes and let me get my trouble shooting repair manual out.
