So drivin my dodge today and all of a sudden it has a miss fire then it just died... Started right back u. And it did it again but it was like somebody was shutting the key off.. Still start right back up.. I remeber replacing the tps with a cheap rockauto for for like 10 bucks i have a napa one coming tomorrow anyways. But already changed cap rotor wires and plugs.. Still the same thing... I am getting a for codes are 12 33 and 55 truck doesnt have ac so rules 33 out.. 12 or because i stole the battery for something else. And i was leaning towards the crank position sensor because my parents mercedes benz was doing the same exact thing... Does this sound like a crank position sensor related... If not tell me what you think
Thanks,
Cam

 

could be a crank position sensor but i don't think the problem would would happen all of a sudden. is there any way you can keep it running?

 

Well it started from at the beach for 2 hours on a foggy night fishing with buddies and it started like my diesel when i didnt have the glow plugs hooked up it would try to start but wouldnt after cycling the kep it fired right up.. Nothing has happed since summer time untill now. And it will stay running it u press the gay but as soon as its let up it will die and theirs no way to keep it running... Tried puming the pedal it just makes start up worse. So im leaning towards the tps

 

i would check the idle air control motor on the back of the throttle body first. it might be be dirty and you can clean it for pretty much nothing if it is dirty.

Iv already tried that... Its clean and works fine
