So I have a 2005 dakota with the 4.7 in it. I had it up on jacks all day replacing the front cv axles and fitting my prerunner bumper, when I let it down and went too start it and it would not start, tried a second time and it fired up with some rich smelling smoke comming out the tailpipe. After I shut the motor off it wont start and I still cant get it too start... I pulled a few plugs and they look mint, pulled the code saying that the map sensor is bad, so I cleaned it. I also checked the tps and the battery grounds. I have the cel and oil can light on on the dash. I checked the coolant and its nice along with the engine oil. Anyone have any ideas about what it may be??

 

disconnect the battery over night and see if that helps

 

got it running and took it for a 25 mile drive, at first there was a S*** ton of water coming from the exhaust, its all good now. The truck starts now but it spins for a few seconds before it starts, it also idles really rough and the lights dim and get brighter when I bring the rpms up... I'm thinking o2 sensors? but I'll change the MAP sensor tomorrow after work(its easier :P) The CEL is still on..

 

I would change the MAP - they aren't cleanable (most sensors aren't).

 

removed and cleaned the map with carb cleaner and the code went away but then one came up for the TPS. changed the TPS and all is good now shifts a little better too..
