87 was the only year that didn't have them from the factory originally.

Second one is washer bottle level sensor wire.
The ballast resistor looks just like the one in the picture. Sometimes located in the vicinity of the one in the photo.

What's the 10th digit in your VIN number?

Look on the relay for the terminal designations.

H means 87 by the way.

Look at the relay and make a diagram of what each terminal in the receptacle is. Then check it for voltage using my earlier post.

Big thanks to 97_4Popper. I took the plug that accepts the taillight harness, and found what terminal was the ground. Pushed in a wire in the terminal and put the other side to the chassis. Turned the key and the pump ran!

The pump ran, so im almost certain thats my only problem. I couldn't start it because the battery died( i left the key on). But im gonna charge it and see if it starts today. I will post back with results.

Well the ground solved the issue of the pump, but now my injectors are leaking. One was leaking very badly, i replaced it with a older one i had and now its fine. But the others are each leaking slightly. Its bit noticeable until you touch them. Im not sure what to think now, it almost seems as if the rail is not sitting how it should?

I also replaced all the lower o rings on the injectors, and it seems to be leaking in the rail side, but these are a flat type of seal, something i cant seem to purchase

BTW, have you been over to comancheclub.com?
All the info you ever need to know about these trucks over there.
I am Dadinator over there.

You should be able to get a whole fuel rail with injectors at a junk yard. I did it when I had one leak on my truck.
Good luck with it.
