Well the truck starts know it was just the fuse I'm just trying to fix the gauge know. The no starting was the ECM fuse.You have 3 wires to the OPS. +12v Power, fuel pump, and gauge. The 12v is always hot no matter if the ign is off or on. It goes to the fuel pump when there is oil pressure.
The Gauge will have voltage with the ignition on and goes to ground through the sensor.
To figure out what wire you need for the gauge at the OPS do the following. Look up the colors or:
Probe the connector for 12v and eliminate that wire as the issue. Key on and see the second wire with 12v - that will be the issue or no 12v. If you only have 1 wire with 12v with the ignition on turn the lift pump on and that will give you 12v back at the OPS connector so you can eliminate the lift pump wire. Jump the lift pump relay by removing it and use a paperclip to turn on the lift pump or you can apply 12v to the OBDI connector and that turns on the lift pump - Pin G - it's the other side of the connector and the other row corner to the two pins you jump to read codes. Literally diagonal. Look up OBDI connector images to locate it.
When you find the gauge wire - use a paperclip and ground it at the ops connector. This should move the gauge. Your wire is either shorted to ground or open. Of course new parts don't mean F all and will be bad out of the box. We are just eliminating wiring
WTS is driven off the glow plugs. So the relay has to energize, driven by the ECM, and then the glow plugs have to have power to light the WTS lamp. As the glow plug relay connector is in the way did you unplug it? Do you have 12v to the one of the glow plug relay nuts? Do you get a SES light with key on indicating ECM power?
You shorted the 12v by the blown fuse. You may have blown other fuses or fusible links. A common wire for 12v power could be OPS and Glow plug relay. There is a lot of fuel heater etc. on the glow plug power wire.
No stock setup.OPS relay works for you now?
I might just buy it from you I fixed all my wires don't feel like cutting back up lol.You going to try again? You can do it!
