I think you will have better luck posting over in the Pre-Power Stroke Diesel (7.3L IDI & 6.9L) Form.

Same issue.....
Alright, so I bought myself a 1990 F250 was told it was an inline 6cyl..... One problem, there's a big 5.8L stamped on the cover and 8 wires coming outta the cap.
That aside, I managed to tow my travel trailer down to work, then the damn thing stalled out on me as I was pulling into the campground. I put it in neutral and cranked it over, it started got me to my site then died. I have changed the fuel filter, but have heard rumours that being a dual tank set up with a propane (not connected) system that there are two fuel filters.
First question, is this true? And if so where are the locations? I only found the one.
Second question, is the fuel pump(s) located in the tank(s) or somewhere else?
I had the same problem with the relay as mine was not located where it was supposed to be, I had to do a little search and destroy before I found those.
If anybody can give me some pointers I'd appreciate it!

To start with you should start your own Thread to ask for help.
That a side if you have a gas 1990 truck you have two high pressure fuel pumps and one is located in each fuel tank. You have one filter on the frame and a strainer at the bottom of each fuel pump better known as a FDM (Fuel Delivery Module).
But it sounds to me that your problem sound more like a spark or computer problem.
If you do not have spark and you unplug the computer and spark comes back you have a computer problem.
If it does not then look at the PIP sensor or the TFI (ICM) module.
