May not be the same. Check the below topic:
https://blazerforum.com/forum/2nd-ge...l-pumps-97674/ AC Delco sounds a safer option. |

SO hows the pump?....couldnt figure out the no splice thing,,,maybe that was when OE pumps were still alviable???....this is my second pump job,,,last was a 2000 jimmy...same mess...of coarse soldered the wires

On my 95 the pump is separate from the sending unit. There is a harness that plugs into the pump, so no soldering or splicing or any thing. |

So far so good, only been about 300 or so miles, though.

Need to find Gray Wire going to fuel Pump 2000 Jimmy 4.3, without dropping tank! Any suggestions out there? Need to check Voltage reading...
|
Anyone out there that may know the color code on the under hood fuse block for fuel pump "PRIME WIRE"coming off bottom of fuse block? ,,need to locate it..
Thanks.. |

Thanks.. It's easy ony 95, but on your 2000 it's still possible. I don't remember exactly, but. I know I've read on here how to do it Do a search, you'll find your answer. Probably in a thread by captain hook, talking about fuel pressure |
Yes, on the 2000 Jimmy, there is a Prime Terminal on the fuse block UNDER THE HOOD, there beside the fuel pressure relay is a Prime Terminal, which goes directly to the fuel pump, uses battery voltage,,key does not have to be on,,it will run the pump as long as it is connected. I am planning on hot wiring that to a inside cab push button switch to prime pump to 61 lbs or so. Having a problem with starting sometimes,,not quite enough fuel pressure, I think due to low voltage going to fuel pump,,as it has a fairly new fuel pump in it,,not by me, but b4 I bought it 1.5 yrs. ago. I have a fuel pressure gauge hooked up under the hood, to monitor fuel pressure,,I leave it there all the time, cause sometimes I don't get enough fuel pressure to start the Jimmy, and if I go out and raise the hood and push the bleed button on the fuel pressure gauge and take the pressure to 0, then it starts right up, no problem. Strange thing,,when I clear the fuel pressure in the fuel line, it starts,,,it will also start with 56 or higher fuel pressure..Think either have low voltage back at fuel pump or maybe some sort of restriction in fuel line or some other odd situation...Has fairly new fuel filter,,about 1.5 yrs. old also. I don't think it is the fuel pump itself, as I get good pressure if I go directly from the battery voltage to fuel pump using that prime terminal hookup on the fuse block that is beside the fuel pressure relay.
thanks for your reply....Weird Problem.. |
