MAP sensor location
#2
Its on the air tube that goes down from the air box to the turbo. Its held in by 2 philips head screws. And it is not called a map sensor any more. I think it is called MASS air flow senor

bigdave that is the iat(intake air temperature) sensor on the intake tube,the map sensor or intake manifold pressure sensor is on the drivers side top of the engine towards the back it's kinda square shaped and has a plug that goes down in the top of it.

I got this from Bully Dogs website. If you scroll down it shows a picture of where your MAP sensor is.

if you pop a code for map sensor [eg: p107] you are looking at the sensor in the intake tube before the turbo. the sensor in the intake manifold plate on the head is coded under the turbo boost sensor

Where is the Air Temp Sensor?
The 2003 Dodge Ram Cummins 5.9 HO has a problem. Does not have any error codes and no idiot light problem. It will not start normally. At first I thought it was due to Cold Minuz Zero degree weather and water in the fuel. It is no 80deg F summer and I have drained the fuel tank, replace the fuel filters multiple times. Also have replaced the IAT sensor and the MAP sensor and just replaced the OEM Fuel Lift pump today that is mounted on the fuel canister. When I remove the fuel filter cover the lift pump works great and fills the canister. Truck will not start unless I give a squirt of Gasoline into the Air filter then it starts right up and runs for Hours, Have done this for 4 tanks of fuel and thousands of miles. Truck will just not start normally. Only one parts left to replace is the Air Temp Sensor #3588 and I can not find out where it goeshttp://www.autozone.com/autozone/accessories/Edelbrock-Pro-Flo-EFI-system-air-temp-sensor-Not-for-sale-or-use-on-pollution-controlled-motor-vehicle/_/N-25e1?itemIdentifier=214110_0_0_ Can anyone show me a picture or any ideas what may be wrong.

It sounds like you have injector issues. One or multiple of them are bypassing back to the tank not allowing the rail pressure to climb up to 5000psi which is need to crank. Do a search on here. Lots of threads about it.
