Intermittent crank no start issue

Hello,

This is common when the TIPM goes out. To confirm lets do a CAN scan which is the future of automotive repair. you can get a CAN scanner from Amazon for about $50.00. here is a video to show you how:

Here is the instructions to replace the TIPM in the diagrams below. Check out the diagrams (below). Please let us know what happens.

The P0137 is telling us the secondary O2 sensors could be shorting causing the issue. can you please unplug it and try to start the engine? Here is the location and guide to walk you through the steps:

Check out the diagrams (below). Please let us know what happens.

Great find! Glad you could get it fixed, that kind of problem can be tough. Please use 2CarPros anytime we are here to help.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.

Every engine requires spark, fuel and compression to run. That's what we have to look for.

These are the basics that need to be tested and will give us the info required to isolate a cause.

1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.

2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.

3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.

4) If all of these things check good, then you would need to do a complete compression test.

Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

Start by reading and recording the diagnostic fault codes. Chrysler makes doing that yourself real easy. Cycle the ignition switch from "off" to "run" three times within five seconds without cranking the engine, leave it in "run", then watch the code numbers appear in the odometer display.

Check and clean battery terminals

If the battery low light will still come on but will not have enough to turn the engine
my suggestion is to get jump and if start then I would check /replace the battery
if no change I would check /replace starter

When it happens, you need to check fuel pump pressure and for spark. First, you may not have spark due to an electrical issue or the fuel pressure regulator could be causing problems. Also, did you replace the fuel filter when the pump was replaced?

Let me know.

The fuel filter is on top of the fuel tank and part of the sending unit. As far as the pressure, it wouldn't set a code. If it is electrical, then it would.

If your not getting the clicking noise, then check the starter relay. Also try starting it in neutral just to make sure its not the neutral safety switch.

Two things to try: First, try a different key. If that doesn't work, use a penetrating oil or tumbler grease to see if that will loosten anything for you. If that doesn't, chances are the tumbler will need replaced.

Let me know if you have other questions.
