Must be the Season, My 1999 F-350 same problem. I had it towed home Fuse 30 was blown and I replaced it, still did not start. This morning I went out it started, Pulled out the scanner, toss out a code that the memory was not stored but as I had the Batteries disconnected this was not a worry. It shut its self off and back to a No start condition I put the battery charger on it, just to top off the batteries. I have check all fuses again, Replaced the CPS Sensor, Ideas???? any help would be appreciated greatly, and would earn dinner drinks and a great cigar to anyone who could help me...

 

Is the WTS working properly now?
Try swapping the IDM relay with the A/C Blower relay. It is a quick way to check the IDM relay for fault. If it starts, and now blower acts up, you found your culprit.

 

Thank you Roland Yes I did swap the relays. No change

 

What about the WTS? Is it coming on, or not?

 

No light, this is what I have done so far.

30 Fuse replaced
Volt meter Checked all fuses
switched relays
replaced Cam Sensor
Charged Batteries
Checked electric connections

 

Have you checked the wiring at the 42 pin connector?

 

Did you unplug thr fuel bowl heater?

 

The on to the PCM? Not yet, and Yes I did disconnect the heater

 

No, the large black plug above the driver's side valve cover. It is known for chafing there.

 

It appears ok, going to check the connections to the PCM this afternoon

 

start checking the connections at all the different sensors

 

Any update? Friend of mine had EXACT same thing happened, other morning, but with the removal/install of key, the "system" worked

I'll let'em know to inspect the wires at the 42-pinner, to rule that out.

 

Tim Remove your under-hood fuse box. Look at the bottom, Look for corrosion clean and drive away ......Problem Solved
