loss of power

coming home from work this morning truck shut down at the end of the driveway. had to pull it to the house with the tractor.

with key off i had a weird noise like something running. Pulled fuse number 8 which is courtesy lamp fuse and it stopped.

plugged up scan tool to read diagnostics. it would recognize that the tool was connected but when you turn ignition to on position it would go blank like it lost power. i was unable to pull any codes due to this

just wondering what would cause truck to just shut down like this.

truck is a 97 f250 stock no mods with 200000 miles on it

What scan tool are you using?

Where was the noise coming from? Cab? Under the hood? Left/right?

What exactly happens when you try to start it now? Does it crank? Does the WTS light come on? Does the tach move (if it cranks)?

Finally got it to read the codes only code was a P0603 if I remember correctly. Not getting any fuel to the fuel bowl now. Tach doesn't move , wait to start light works like it should. It cranks but no fuel is making it to the bowl.

Could this be a fuel pump issue? It has dual tanks on it and neither one is deliverin fuel to the bowl. Could this be a relay or bad fuel pump? What are the odds of both pumps going out at same time?

This is a 97 correct? If it is stock it will have a single two-stage mechanical fuel pump in the valley of the engine. You may need to see if it will draw fuel from a standalone container plumbed directly to the pump. Crewcab, Extended cab, or Regular cab? The reason for asking that is, my 94 CC had a short in the wiring for the rear passenger door courtesy light circuit and power window circuit. Cheers!

Yes this is a 97. I was under the assumption that the fuel pump was in the tanks but I will definitely check the valley. It is a 97 extended cab 4x4.

Am I correct in understanding that this truck has only one fuel pump instead of 2? Nothing inline on the frame rail or in the tank (s)?

One fuel pump, under the "Darth Vader" cover, mechanically driven by an extra lobe on the camshaft.

Sorry for the delay in replying back. I just wanted to let everyone know what I found to be the problem.

we checked all the fuses and found one 30 amp maxifuse burnt out. we replaced it. We were not getting fuel to the bowl so we replaced to fuel pump as well, also replaced the cps just in case that may have been the problem. The truck would crank and crank after this but still would not fire. we run some test on it an found that the ipr was not working.

The wires on the ipr connector were bare at the end and had been pressed together keeping it from operating properly. we separated the wires and reconnected the connector and it fired right up.

now we just need to buy an ipr connector pigtail kit and ford wants like 75 dollars for it.

Thanks for all the assistance and input from those who commented on this post
