2001 Dodge Ram Intermittent Starting

2001 DODGE RAM

I have a 2001 Dodge Ram 1500. I have recently encountered trouble starting. Sometimes it will start fine. Other times it will turn but not fire. I had it jumped last Sunday and it started every morning. I would start the vehicle in the mornings at 6:30am, again at lunch 12 noon, and again at 6pm when leaving work. I would go out to the vehicle at midnight and it would start again. If I left it overnight without starting it would not start the next morning. Yesterday it returned to the turn-but-no-fire routine. I swapped out batteries with my son's truck and encountered the same problem, no fire. The odor of fuel is very noticeable. I have considered replacing the electronic ignition coil but not sure if that is the root of the problem.

Scan for codes then check resistance of crank sensor it may be to high and not allowing truck to start. Check against a new one as we have no specs for that.

Scan for codes? If you are referring to electronic codes the check engine light never comes on to indicate a potential problem. Please advise how one would check the crank sensor. Would the crank sensor allow the vehicle to start right up one morning and the following morning the truck would not fire? Are there any other causes to why the truck would simply turn but not fire?

You have to check resistance with an ohm meter on a crank sensor. If the ohms are to high then it will cause your problem also you need to wiggle the connector then try to start the truck if it starts then you need anew connector. In your first reply you never stated whether or not you had scanned for codes or not we don't know that. You have to scan to see if any sensor is wrong but with no light it's probably crank sensor or the anti theft unit which you can try to reset bu ti'v e not worked on a Chrysler product in some time so you need to refer to your manual or a dealer or go online. But I kind of think it's the crank sensor.
