Question about 2003 Pontiac Montana

1 Answer

Wondering if I can change the starter on my 2003 Montana with a starter from a 2002 Montana?

I just picked up a 2003 Pontiac Montana, the previous owner said the starter was gone, replaced it with one from a 2002 Montana, however the motor won't turn over at all, wondering if I need to look at a different starter or do I need to look into something deeper?

SOURCE: Changing the starter solenoid on a 2000 Pontiac Montana

On your van the solenoid is attached to the starter. If you can get a solenoid separate (i don't know if you can) then you will need to take the starter off and remove the solenoid (2 screws holding it on) and the wires (on red and one black i believe) pay attention to which wire goes where because you don't want to reverse it on the new solenoid.

I beleive you need to change the Power Window Switches Module in the drivers side door panel, as these connections are interlinked within this module and it is usually the first part that fails. Especially that you already changed the switches & motor in the passenger door and it still does not work. Once you remove the dual switch module in the driver's side door, you will understand what I mean. Plus it is really easy to access. Good luck! I have the same model, Claude

SOURCE: 2002 Pontiac montana won't start

The problem is most likely a bad connection at the battery or the underhood fuse panel behind the battery. Recheck these connections and included the ECT (Engine Coolant Temperature) sensor (wires and harnesses).

Fuel system? Relative to how gasoline engines work, one that has sat during the 8-hour workday is nearly as 'cold' as one which has sat overnight (overnight will dip mebbe 30*F more, but this is practically irrelevant to an engine). The one major variable is volatility of the gasoline, which is affected by atmospheric temp especially when the engine isn't warmed-up. Starting this month (and continuing until fall) the 'blend' of gasoline will change from 'winter' to slower-vaporizing 'summer' in most regions of the country; you may have it now, or from some specific gas station.

If the car's Inlet Air Temperature (IAT) sensor (in the airbox), is faulty and reading too high, then the combination could push your engine 'over the edge' in terms of the PCM trying to set the proper richness for 'cold start.'

That'ts the sound of your starter trying to pull enought power to turn the engine over. Sounds like you need to charge or change the battery - have you tried getting a jumpstart? Get a jump and drive over to a shop where they can check your battery and/or your alternator.

Check that battery connections are clean and check engine ground. Also find what's clicking and make sure it's well connected and working (likely the relay you are looking for.)
