Engine/Transmission (1998.5 - 2002) Trucks dieing / code P1693 ?

[CEbbert]

Drove truck today after not driving for a week. Made it about 8 miles then died, no surging, died without warning. I cracked the fuel line, had fuel, cranked for 30 sec. then started. I made it aprox. 1 1/2 mi. and it died again. Got started and same thing with a ploom of white smoke when I was reving it up. Retrieved codes and it is spitting out P 0602 and P1693. I don't understand these. Can you please help with some info!?

From the service manual: P0602 = ECM Fuelling Calibration Error which means that your ECM may have bit the big one or has some type of internal error.

I believe that 1693 is a companion code meaning there is a code in the ECM that you'll want to read. Sounds like to might be needing an injection pump.
good luck

Just a shot but how full is your fuel tank? Acts like it ran out of fuel. Then when you stopped it had enough to go a little further. A friend of mine runs out of fuel showing over 1/4 tank. Go under the truck and tap on the fuel tank. Hope it help and saves you a pump for now.

I had a 1/2 tank, I did put 3 more gallons in it, thinking the same thing myself. I have the same post in the 911 column. I am wondering if the VP 44 can go bad and send a message to the ECM? Or is the only code you get with the VP 44, the 0216 code? I installed a Air Dog 100 on it about a month ago, could this at all have screwed up the calibration on the ECM? Thanks for the responses so far.

No, the AirDog would not screw up the ECM.

Godspeed,

I had a ECM go "tits up" a couple of years ago, and someone on TDR was reflashing the ECM. They had to know year, auto or not I think.



BTW I took the reflashed ECM and zip tied it out between the engine and the fender well to insure pleanty of air flow around it. Strapping it to the side of a hot engine I do not think is a good design. Use a IR gun and check the ECM temp of a running engine after about an hour, it will surprise you how it ever actually does not die within a year with those temps.



Dropped the ECM case temp about 40*, ie less heat stress.
