My 1996 Dodge B2500 is hard to start when it's cold. It takes about 30 seconds of cranking on it to finally start it. After it's warm, there is no problem at all, starting or running. I heard about the intake air temperature sensor can cause this issue. I bought a new one from O'Reilly's, put it on and it did not fix anything.
It's hard to say what could cause the problem without testing a few sensors with a multimeter or scanning the fault codes if it has an OBD port. But my best guess is the coolant temperature sensor, or MAP/MAF sensors depending on which one it has.
@@PrecisionMotors-ib9cy Thanks. I get over my head when trying to diagnose a problem. I am also no good at using a multimeter too. I also don't have a repair manual for this van either so without that, I really don't know where or what the MAP/MAF looks like on this van.
@@PrecisionMotors-ib9cy Sorry for a delay response, didn't know. The engine is a 318. And you suggest it may be the "coolant temperature sensor". Isn't that the sensor to the dash gage, it's next to the thermostat and is extremely difficult to get to? If so, I already replaced that sensor a few years ago while doing a water pump job and the dash gage works fine.
In most cases even when the IAT isn't integrated, its two wires run through the MAF sensor connector so I would check if the MAF is reconected properly. Also, inspect all the wiring between the IAT and MAF sensor, and check the IAT pins and terminals inside the MAF connector. Other than that, my only guess is that the IAT is bad.
DID YOU FIX IT? i have the same problem. my shop changed out my MAP sensor and now it says that my IAT is high. its reading -40 degrees. and I changed it for a new one and nothing changed
@Darren-pq5oc I figured out my iat and maf was indeed integrated. I bought a cheap Amazon maf with integrated iat. It was bad out of the box. Ultimately, I cleaned the original maf with maf spray cleaner and reinstalled. Everything works great now! 👍
It can lead to difficulty starting the engine, especially when the outside temperature and engine are cold. That means longer cranking than usual before the engine fires up. But it doesn't cause no start or no crank.
@@PrecisionMotors-ib9cymy car broke down.. engine would turn on but as soon as I pressed gas or tried moving it sputtered and lose power and stall.. after many attempts the car barely even started afterwards... now it's not even starting at all i got P0113 codes
@@cristianmotagarcia570 at the end it had nothing to do with the code I had. It was the egr valve that was stuck open and let too much gas into the engine.
@@cristianmotagarcia570 if you have a diesel car it could be the egr if you have the same symptoms as I mentioned above. One way to find out is by opening the egr return gas pipe (to stop excessive exhaust gases back into the engine due to the egr valve failure) and try starting the car if it does start as it should, it's the egr
