No voltage to FIPL

[NTOLERANCE]

My e4od started acting up again I have second and third. I have no pos voltage going to the FIPL. Fuses good. I must've lost a wire connection somewhere this past winter and then it came back. Now it's gone 100%.

Anyone have a schematic? I'm going to trace Down wires.

Think I found it. This looks like the teca power relay?

Well that was the blower motor relay. Any idea where the teca repay is?

Thanks. Relay is working. Has some corrosion but cleaned it up. Has power coming out. I still have no power to the flpi

Save that to your pc and then you can zoom way in where ya need.

How ya making out? Find any power or ground issues to the TECA? If it's well grounded and receiving power but no power is coming out, I guess it's toast? If it doesn't receive power,the OD cancel light should be on dimly all the time.

When your testing for power at the FIPL/TPS are you using a well known ground source,like the terminal right on the trucks battery for your multimeter?
I ask because,if your using the TPS ground harness and that is what is bad,then it'll trick ya.
Though I suspect you would have already long since tested the ground for resistance anyway,never hurts to see what steps someone is on,just to make sure.


If it turns out you need to replace it with a reman,here are the updated parts #'s.She'll be controlled much better (perfectly imo.i wouldn't change a thing) with one of these.

Sorry - been swamped. There is a black wire going to the trans controller. Its been cut out of the harness and there is a blue wire taped to it. This blue wire is wrapped around the left head lamp. I assumed this blue wire was for some sort of extra lighting the PO had. Well its not need to find out if its supposed to get pos or neg power. not sure this is my issue but its clearly something that need attention

Ok. The black wire is number 7 which according the the schematic goes to the trans temp sensor. It's never been hooked up since I got the van.

Found it. It was the relay. It would carry voltage but not a load. How much current can the ecu pull ? Well It's fixed at any rate.

Hope you are taking it to feed it........
