Truck missing bad

Recommended Posts

I have a 1998 24 v 3500, It left me sitting on the road with a 40 ft camper . I have replaced the fuel filter, fuel presure stays around 17, there are no codes, was just wondering if it could possible be a crank shaft sensor? or any other ideas. It just keeps cutting out and back on afraid the u joints and transmission will go,thanks

How are you checking for codes? Your 98 will need an obdII scanner to check them. The IP can go with out codes on occasions. I would think you would have a code for a bad sensor.

I have a scanner it reads both ecm and pcm codes, no codes Not sure if the vp will always give a code or just fail.

right now I am grasping for straws till the weather clears a little thanks

Just cutting on and off even misses at idle, at 50 mph it will almost jerk you out of the seat, no power, 1 gear to get the rv in to the parking lot

Ok, so it misses under load... Will it run smoothly otherwise? I recently had a VP on my 2000 go... It would idle great, and run good to about 1/3 throttle and then cut out completely and buck.

Now it will not start and I have a 1689 code, I have fuel to the pump and power to the pump, but nothing out of the injector lines.

Just completed the install of a VP-44 from DAP, truck fired up and runs great. Would like to thank everyone here for all the help and support, expecally the tech at DAP which was very helpful. Truck had no codes till it completly went out and only a 1689 then, missed and no power for the last 1000 miles. Hopeful it will be good for another 130000 miles.
