You bought from Autozone,and now you have to splice,look at both and use the same wires from old pump to new one,look at both connectors and do it the same as in both plugs..

SOURCE: wiring diagram for 01 isuzu rodeo stereo

A few weeks ago I bought a new JVC stereo for my 2001 Isuzu Rodeo. I was advised that using a wiring harness would be the best option to install it. I spent an entire Saturday going from one store to the next (Autozone, Advance Auto Parts, Radio Shack, etc.) looking for the wiring harness specific to an Isuzu Rodeo but, to no avail. I searched several online sites looking for one and finally found it at http://www.beachaudio.com/ . The cost of the harness was under $10 and with express shipping I only paid about $20. Since I ordered it on a Wednesday night with 3 day express shipping, I assumed that I'd receive it the following Monday given any processing time and the weekend but, it was delivered to me just two days later. My husband installed my new stereo that Sunday using the harness that I purchased and it works great! Hope this information helps.

Wiring diagram delphi sa10001

Did you check the fuel pump relay in the fuse center under the hood? Maybe you blew the relay and really didn't need to replace the pump. Did you recheck all the wired connections with a DVOM? Never ever replace anything as important as a fuel pump with out double checking all connection and checking for voltage before putting it all back together. Hopefully you didn't put the gas tank back in yet. Oh and you can swap the relay with one of the others sitting next to it i the fuse center, just remember to switch it back when you're done.

Need color code on new connector

Just did my fuel pump on the 2001 isuzu rodeo. Well here is what you need to do about the different wire colors. First disconnect your negative battery. Drop the fuel tank and replace pump. Remember to have a splice kit in hand. Ok now here is how you connect the different colored wires. Black goes with black. Gray goes with black and orange wire. Purple goes wit blue and yellow. And the last wires goes together. I hope this helps.

Fuel pump in my 97 rodeo works if i wire it to the battery,but does not work when i plug it in where it belongs.I've checked the fuses and they all look fine.

Same thing happened to me on my 1996 isuzu rodeo. My fuel pump worked part of the time. I actually bought a new one, then tested the old one when I removed it. Like you, I hard-wired it to the battery. It turned out to still be good.

It turned out to be a bad ground connection from the fuel pump. You can check it by --- 1) hooking the fuel pump back up where it belongs, 2) splicing a wire from the ground wire coming from the fuel pump and 3) grounding the wire (loosen a bolt head on the undercarriage, stick the stripped wire tip between a bolthead and undercarriage surface, then rachet the bolt head back tight. Then 4) just turn the ingnition key and see if the fuel pump engages and the engine starts.

Good luck!
