two days ago started truck for about 1 hour got home shut it off. 5 mins later tried to start it but would not run. pulled fuel filter out to see if there was any fuel in canister. canister was full. put filter back in bumped starter and lp started to run and truck started. today ran the truck to work. started fine at the end of day. went to wendys to get something to eat. came out and truck didnt start. did same thing i did the other day and truck started right up. but on the way home check engine light came on and lost gauges for about 2 sec. had codes checks and said it was camshaft position sensor. my ? is would this have caused my problems of starting the other day or do i have other problems?

 

Do you mean crankshaft position sensor?

Nope it would be the camshaft position sensor.

The camshaft position sensor is under the ip where the timing pin used to be. Yes it can cause a problem like that. Later 7.3 Powerstrokes are notorious for it and usually have similar symptoms.

 

i hope that fixs the problem. i just put a new ip in a year ago to the day. i dont mind putting a new lp on but ip wouldnt go over to well. i think that it is time to upgrade the lp anyways seems how it will already be in the shop. do you guys have any ideas on an aftermark upgraded lp? not sure i want to go to the extreme of a fass system. thanks for the help!

 

I had the same problem but mine was the crankshaft position sensor behind the starter, did the same thing would not start sometimes and I lost rpm for a few minutes. I replaced it and so far it has been fine.

 

i also had the problem that you had mine was also the crankshaft sensor behind the starter but the gear grenaded in the oil pan so you should be able to just change the sensor and be back running back to normal

 

You could go with the fass hpfp if you do not want the whole system. A full big line kit will help also.
