I just got my tst wiring harness back in today and after hooking it back up for the past hour i go to start and it takes forever before it finally does start. The truck is idling like it has a cam in it, like very bad. Smells bad and it is pouring smoke out the stacks. I got a water in fuel light, and a couple low circuit voltage codes and a throttle position sensor code. What in the world is wrong with this thing?

 

you have the rail sensor plug backwards

 

Wow thats unbelieveble...Rpainter thank you very much thats exactly what it was....i have hooked it up so many times with the r37 but only once since i have had the r49, sure had it backwards, again thank you very much man

 

Well now i have another problem....the truck is trying to die now. i will ease into it then it will almost die, like drop to around 250 rpms then come back up to 750....when i turn the truck off there is white smoke still comin out of the stacks. Any help would be appreciated

 

Bump..Lol, it aint blowing white smoke anymore but it is still trying to die when i get on it. Idles fine but when i try to lay into it it starts this again..I give up for the night. I appreciate any replies

 

with that low of a rpm you should have more trouble codes check and let us know

 

Was your truck built before or after June 2006?

 

The truck was built before june 06, i believe it was late 05 when it was built. The codes are0341 and p0336. The problem lies somewhere with the tst, the truck/smarty was fine before i put the tst back on.

 

I say check all the connections again if everything looks fine and still runs bad try pulling the harness again fire it up and see if that is the problem. If the problem goes away call tst

 

I think i will do that...i know everything on top is fine so im gonna disconnect then reconnect the camshaft and crank shaft sensors and try it again. Thanks for the help bud.
