on my 2002 3/4 ton 4x4 the truck seem to stall and the accelerator doesnt resspond. the truck smokes white and then it returns to normal. Could this be injector problems?

Gasoline and/or water can cause white smoke.

Get the codes from the odometer by turning the ignition switch on/off/on/off/on and leave it on (not running) and post them.

I checked the codes and it came up with ECU 1693 and P0216

Injector pump bad, also check lift pump pressure before you put a new one on

Checked fuel pressure on the schreodor valve on the side of the injector pump and it would idle at about 7-8 psig and when i would accelerate it would drop to as low as 2.5 to 3 psig

Your injector pump is toast. If you're under warranty get to a dealer. If not, $$$$
Sorry.

I had the same codes and same problem turned out to be the apps or tps which ever you choose to call it .

It's the Injection Pump. My truck had the dead pedal issue and smoked pretty bad when I stepped on the go pedal and the smoke wasn't white more of a greyish color. Had pump replaced and now have beautiful black smoke and no dead pedal. Go to your dealer have them warranty the part. You will have to pay a deductible of at least $100 dollars but it's much bettern then paying for a $1200 part.
