97 That Stalls After 5 Minutes

[97 puller]

Anybody Help!! My 97 F250 has a problem. It first appeared when I was driving down the highway and it acted like it was running out of fuel. It stalled and restarted twice but stalled again. I left it and came back later to put a new fuel filter in thinking it was plugged. It started up and I took it down the highway and within about 4 minutes it stalled again, but this time it would not restart. I had it towed to my plumbing shop and I talked to a few locals and they said it was probably the mechanical fuel pump mounted above the cam shaft. I replaced the pump. It started rignt up and I let idle for about 5 minutes and it stalled abruptly. The oil level is correct. Anyone with any suggestions would be appreciated!

Could be a Crank positioning sensor. These go bad from time to time, and will sound like what you described.

Best part is, it is only $27

sounds like its possibly the cam sensor , if you have a way to pull the codes
that would be the first thing i would do see if it has a p0340 or p0344 in memory, or any codes for that matter , start there

Yep cam sensor, takes about 2 minutes to change and you can get them from $15-$25

thats got cps (cam position sensor) problems sounds like. they r expensive but id recommend putting a international cps in it. its the blue ones, i put one in my OBS and it ran connsiderably better from it.

Thanks for the advice. Where is the cam sensor located on a 97 7.3 liter?

its located on the passenger side of the front of the motor. its right above the harmonic balencer at about the 11 o'clock position of the balencer. its pretty much the only sensor down that far on the front of the motor.

My CPS acted the exact same way right before it went bye bye. Simple to fix. Lucky for me I had taken the advice off another psd owner to keep one in the truck.
