01 3500 Stumbling
 

Hi, our stock ton truck is stumbling and spitting the last couple of days, 4 or 5 times a day, shortly after start up, shut the truck off and it seems to restart and run ok. One of my guys was leaving the shop a little will ago and I saw a puff of blue smoke and then he had to pull over and re start. The only code is the 1693 and I understand that means a hidden code. The truck has about 65000 kms (35000mi). No dash warning lights, and I don't have a fuel pressure gauge. Any Ideas? Thanks in advance, this is a great site, Fred

when was the last fuel filter change?

In the spring, I'd say May, FMK

I get to beat the rest of these guys to it![laugh]
Better Put a Fuel Pressure Guage on it,went with the Edge Instead..I ran my truck out of fuel one time and it did about what you described,so I'd guess that you got a plugged filter,or water in the fuel maybe.
I was looking at this one,someone will tell you that one sucks,or there is one better,but this gets 'em primed to help[laugh]

Good Luck:cool:

change the filter then see how it runs.

hopefully it's not the VP

you should really have a fuel pressure gauge to check.

if the filter does not fix it my next vote would be for the lift pump and VP44:( :o

update
 

Update, replaced fuel filtre, looked nasty. Worked great all day, just started home from home, going about 40mph, truck stumbled and died. Started after a couple of trys and runs fine again. Showing codes, 1693, 0230, 0217, any ideas? Employee thinks its running low voltage when it quits, I didn't notice, thanks FMK

230 is lift pump voltage, and 217 is engine over heated
