What is this miss??? Truck started to miss the other day like it had water was not getting fuel. This only happens right after I start it and then it clears up after a few minutes and runs normal. Does not matter if the engine is hot or cold. Also I get no water in fuel light. I did a apps reset and had no problem for two days and then I did the code thing with the ignition key and it came up with a P1693 code and then the miss started again, same thing! Did the apps reset again and will see what happens tomorrow. Oh I changed the fuel filter before the first apps reset and no change. Anyone have any ideas, LP or?? What is a P1693 code? After it displayed the code it went blank and then said r--done? What gives????

 

My truck did the same intermittently, I found that my lift pump was running intermittently and I had a leak around the fuel filter seal, I replaced the on-engine lift pump with the in tank pump and installed a FP gauge.

I am not sure if mine was an air problem or a FP problem but it is fixed.

 

p1693 done , then wait a little bit and it should tell another code wait till the milage comes back up before you turn it off

 

Thanks for the replys guys. I'll have to try to reseat the filter cap to make sure that there is no air leak. When I get home I'll do the pump at the tank and fp gauge. I had the scan done at AutoZone and it came up p0216. It says The PCM has determined that there is a discrepancy between the "actual" and the "desired" injector timing. I'll have to figure out what that means and then how do I fix it!

 

bad news that's your injector pump (vp44) one grand and 5 hours and you will be back on the road sorry to tell you that .

 

Well that's disgusting if its the vp44!!
