Go to www.fordfuelinjection.com under getting trouble codes. Its easy and free. Also a Haynes manual has a ECC trouble codes section. Let us know your codes. List the flashes just how you read them. Once you get your codes start checking each part with the lowest codes first. Sometime one code is caused by another code. So you think your intank fuel pump is going bad? <!-- / message -->

Is the fuel pump a Ford? You will have to drop the tank or cut a hole in the floor to gain access to the pump.
I have the procedure in the tech info thread at the top of this forum, "pulling eec-iv codes".

The fuel pump i have (mounted on the frame rail) no clue on what make car it is for... i was orginally going to use it on a 1930 model A tractor frame instead of using the old grav. fed fuel. i will have to get a fuel pressure tester to see if the pump can sustain around 40-45 PSI for fuel if it can i will remove the 2 pumps on it now and put that 1 on it.

Does a replacement distributor come with a TFI module? I thought you had to use the old one when you replaced the distributor. Your problem sure sounds like a TFI problem - usually fail after running a little while and getting hot. Then restarts after cooling down a bit.

I replaced my distributor and it didn't come with a new module. Make sure when you reinstall your new module you use Dieletric grease to keep the moisture out. if any water gets between your module and distributor it will start to corrode and cause more problems in the future.

fuel pumps
The older trucks had a hp fuel pump on the rail with two low pressure in the tanks. Then i believe ford updated it to a high pressure pump in the tanks.

There is a guy on e-bay selling these modules for 24.99 + 5.00 S&H, he said he had plenty in stock. Mine is in the mail and I will post latter if that is the problem. Just thought I would throw this out there.

heres a tip for i found for removing fuel pumps , loosen the bolts on the left frame rail ,then remove the bolts on the right side of the rail , then you can raise the box with enough room to get at those darn things.
