motor cranks but wont start.. Bad cam sensor?

i just happen to install my 4" turbo back exhaust... First time it wouldnt just not crank but second time it did along with a 'service engine soon' light... Didnt pay much attention to it and went to test drive with the new exhaust... all went well, parked the truck and a few mins later it started fine..

Went to Advance Auto parts to see if there were any codes in the computer,there were no codes but the 'service engine soon' was still lit...

Went to start the truck to go home and..... it just wont start... the "wait" light for diesel warm up doesnt come on.. so im thinking its that cam sensor??!?

Im waiting for a tow truck right now to take it home.. Got the laptop with me and decided to start the research while i wait..

Its my theory correct? or can it something else?

i just replaced the cam sensor with the blue international one.. Same results.. it cranks but wont start.. no movement on tach and no "wait" light either..

i was really hoping it was just the cam sensor but im puzzled now... any help would be really really appreciated..

this happeded soon after installing the new exhaust but i cant of anything that could have gone wrong during the install..

Unhappy running out of ideas...

just changed teh #16 fuse and nothing changed..

unpluged the diesel heater element... nothing changed..

Opened the fuel filter.. there is fuel there alright, when i put the cap back there was more fuel than when i took it out.

I unpluged the batteries to resent the computer while they are beign charged since they got weaker after every failed crank..


edit: Cant believe no one have been able to give out some pointers... Running out of options and will have to take it to the dealer ..

I can imagine their faces when they see the tymar intake, new blue cps and chip in the computer..

Make sure you check your oil level. This will definetly cause this problem. Not sure why the wait to start light is not coming on unless bulb blew???

oil level is a tad lower than teh full mark due to the incline..

when i turn the key i dont hear the pump come on..

In two ocations i heard what to me seems like an air pump very close the top/passanger fender..


Under the battery (driver side) there are two sounds about 3 or so seconds after the key is turned in the ON position.. bubblign air and then what it osunds to me a relay/solenoid that goes on and then off (one sicle)..

The withces decided to hunt my truck....

Thats the vac pump.

You could have a bad fuel pump. Been replacing them latley and check fuel filter. New fuel is rumored to be doing it but I cant say it is or isnt.
