Hey guys, kinda stumpped on this one,
Truck is an 01 24v with 100k 7x13 injectors, hot rod pump, Fass system, never seen salt. Bit of head work done to it also.
Coming back from a friends house the other night, laid into it a little bit in 5th gear. Coming back down from rpm seemed like it was vapor locking up a touch. Took the nearest corner and headed home, very rough idle, white smoke and it dosent clear up anywhere in the rpm range. Cracked a couple lines at the motor, not air in the system. Fuel pressure is good, fass is running as it should. The codes were P1693, P0602, P0500. Turned the smarty back to stock reset codes and shut off the drag comp, No change. Oil is clean and so is the coolant. Got any suggestions guys? Work schedule is all over the place so diagnostic time is out the window.

 

Clogged injector?

Check air filter, is it the stock air box?

Check the APPS, do the APPS reset procedure if it does not miss when cruise control is set...

 

Change your fuel filter...

 

You have any fuel leaking from the injector cross lines? Any fuel leaking out of the back of the VP? Is the injector retainer bolts tight?

code 0500 is a smart code, the 1693 is that there is a code in the ecm.
