1992 ford 150 4.9 automatic. It stopped running at stop sign. Had it towed. Later, got it to run, but had little power. Now, will not run at all. Had ignition module tested (good), fuel pump does not run (has power), coil tested (good), no check engine light (?), power into distributor (don't know about power out). No fire at spark plug wire. respond to ridinhigh.

If you have your owners manual it will be in there.

Is it automatic? Have your garage run a computer diagnostic test.

run the fault codes as the problem could be a problem torque converter clutch servo/solenoid

By "...but is firing." I assume you mean that it has ignition spark at the spark plugs? Have you checked fuel pressure? Is the fuel tank empty? (That will definately make it lose power and stop running.) Do you have injector pulse at your injectors?

The fuses for the trailer tow adapter are in the normal fuse panels.

Engine Compartment fuse panel
101 - Is the battery charge circuit ( hot in run position )
20 - Left Stop / Turn fuse
19 - Right Stop / Turn
5 - Trailer tow reversing lamps & Trailer Tow parking lamps

Cab Fuse Panel
23 - fuse for the relay for the trailer tow battery charge circuit

All of these are in the owners manual

If you did not get an owners manual with your truck ( purchased used ), you can download one from Ford :

Changed the fuel filters lately? Also, may be a defective pump or clogged in-tank pickup. Pump should put around 40psi to the rail.

If you have a stick shift, you rent a 2 wheel tow dolly and run the front tires onto it and strap it down. Put the truck in neutral and away you go.
If you have an Automatic you want all 4 wheels on a flatbed or tow trailer. You rent a car hauler trailer and piggyback the truck onto the trailer. A good rental will know the weight and rent you the right trailer.

There are a few fuses for the trailer tow adapter.

1st, is theodd location on the 97-98, engine mini fuse panel has a 20 A fuse forthe stop / turn lamps. Have seen it covered in tape from the factory onsome 97-98 MY trucks.
This is on page 142 in the owners 1997 manual, all the revisions for the 1998 owners manual I have seen do not include this fuse box for some reason.
