I have access to wiring diagrams for any vehicle available in North American 1983-present. Sometimes I can cross it over to Rest Of World cars. If you need schematics for anything, feel free to email me. alandaeric at hotmail dot com

ITS DEAD
Tried to start the truck the other day
- MegaTune comm works ?
- yes
- LCD works ?
- yes
- no rpm signal. What about wheel_error ? (Switch LCD to page 01 with mlp01 and check if W.. increasing ?)
- nothing
- no fuel pump activity (untill I hit the brake pedal, then it wouldnt shut off) nothing working as far as I could tell.
- Put the ecu on my test bench, all sensors readings look fine in megatune, I can upload firmware, everything looks ok untill I try and do an mdh command. I noticed the fuel pump channel doesnt turn on. Tried some other channels, none of the P259 channels work at all, all the I259 and S259 channels are always grounded, mdh does nothing. All this happened after I uploaded the 1.0.23 firmware. The truck was running before but it was barely able to stay running, and was gradually getting worse but that may be related to playing with some settings. I reloaded 1.0.18 again. I can load my config and tables everything no problem so I assume the firmware side of things is all in tact.
- I went out to the truck to check the wiring, found 1 wire ripped out of ecu, the EC36 pin 26 ground wire. Connect the EC36pin26 ground ASAP!
- Did already but have yet to hook up to that harness, test bench is a completely separate harness on its own
- Ground and GND5 (and flyback) are the most important wires to have connected all times when the ECM is powered.
- I know, should have been more cautious for the amount of times I have had the ecu in and out of the truck to try and fix my trigger problem, I should have watched for wires breaking.
