Have a really hard look at the the connectors, Might have to open 'em up in back a bit, so you can see the actual terminal connections, if the wires themselves look fine, it's gotta be one of the connectors.

 

no they both show .3 to my recollection which is the same thing that shows if I touch the leads together or if I test on a single piece of separate wire by itself

 

question: can I take a piece of known good wire and splice it from one end to the other and bypass the whole harness to double check it? In theory this should work for testing purposes right?

i guess that circles me back to when I touch the leads or test a single piece of wire and it shows .3 ohms...

are you saying when testing from pin 85 to the pcm or pin86 to the pcm it should show something else? If so what?

when I touch each end of a known good piece of wire it says .3ohms

what am I missing? What numbers should show when I connect the pdc end to the pcm end?

 

You could use a piece of wire and bypass the wires to see if it helps

 

ok I’ll try that first thing in the morning thank you.

 

The video does not help . Can you take a picture of the fuse and relay diagram inside the lid ? Maybe it changed for one year in 97 (98- has a different PDC altogether) but the 96 FSM shows the fuel pump and ASD relay being two of the large ones.

Edit: Nevermind found some pics on the Internet of PDCs with the fuel pump relay in different locations.....

 

yea the video was just to show my fuel pump relay.

 

Your meter needs to be re-zeroed. When you touch the leads together, it shows .3 ohms. It should show zero. (the manual for it should tell you how to do that.)

Have a test light? Hook the clip to the positive battery terminal. Poke it into the relay socket where the brown/white wire is, does the light come on?

 

Sorry if if missed something here but to me it would indicate that there is a problem with the pcm.
This is back in the first few pages and if you have the pcm connected and ignition on it should only prime the system then shut off. If the pump is running continuously(ignition off pcm hooked up) there is a problem in the pcm. Pcm supplies the ground for the relay, If you disconnect it and it stops there is your problem(pcm).
I assume you are trying to read voltage? Should have one lead on battery positive and the other(lead from the pcm that supplies the ground) in this pin. Don't be concerned about the 00.3 even my Fluke auto ranging meter does it. And if you are checking continuity you should be using the one with the pic of the diode(the one to the right of where it is now)


Another thing i seen don't push the test lead into relay terminals, This can stretch the terminal and then may not make the connection to the relay. Use the clip with a piece of wire into it instead.

 

I don’t but I was about to go buy one in a little bit. Should the pcm be plugged in or unplugged when using the test light in the socket?
