To bad with the crank sensor. At least the old one was f'd up. So far, you have reported 43, 45 and 49lbs pressure. And you say the needle on the gauge was erratic. Some thing is not right there obviously. I'm sure CM will be back with some further assistance on the subject. Meanwhile, if the thing is running crappy and missing, I find it hard to believe there are no codes. Just for S's and G's, try unscrewing the precat o2 leave it hanging and see how it runs.

 

i think 43 was a wrong reading i think ididnt have it screwed on all the way as i was in a hurry.... when its ideling its 49 psi and when the key is juss in the on position its at 45. his is weird it juss stopped running and then i put a used pump in thinking it was the pump i just bought a new one and now its still doing it. Im sick of this i juss want my truck back. I miss driving it

 

I'm just curious, does the CEL come on momentarily when you turn the key to just the on position? (not start)

 

yeah it comes on .... it is on cause i unplugged my IAC sensor but i cleared that code. I dont know i juss want it fixed lol DO you have ANY idea ?

 

Still have that O'Reilys cam sensor in there? Did you add an O'Reilly's crank sensor into the mix as well?

 

yeah its all borg warner which is a really good brand. I didnt go with the cheap masterpro kind. SO thats not a problem.

 

Isn't it?

 

do what lol .... i have never had a problem with borg warner. I juss dont know ne more ...

 

As I said before, the dodges seems to be extremely sensitive to aftermarket sensors, especially the 'important' ones, cam and crank sensors..... There are many many threads on here with reports of folks have trouble after doing a repair, only to find that replacing some sensor or other with one from the dealer solved the issue. Sure, you pay more for the part, but, you also (supposedly) get a higher quality part.

 

im pretty sure i can go buy these new ones and it will still run this way. Im juss upset i dont know what to do ne more ... might juss save up for a new engine !!!
