2005 Jeep Liberty CRD Won't Start - At first no hot start...now no start at all

[Geralt]

What's wrong with your Jeep Geralt?

There is the pump pressure regulator that vibrates

Hi jwilinski, the crank and cam sensors are available from Bosch at a third of the price that Jeep will charge you. They are easy to change out! Also be careful of using Chinese made Bosch knock-offs as they work fine for a while and then suddenly fail - prices are attractive. The part numbers are as follows - note this is for the 2.5 CRD but numbers are similar for the 2.8CRD:

Crank Position Sensor - Jeep 050 668 82AA and Bosch 0281 002 434.
Cam Position Sensor - Jeep 050 668 56AB and Bosch 0281 002 667.

If you look on the actual sensors you will see the Bosch number on them. Also a Google search will confirm the Bosch and Jeep part numbers!

Another thing to try is to cycle the ignition key on and off about three times and stored codes will come up on the milage display. You have to be quick to get the numbers written down(on paper) as they show up and disappear fast. Then you can Google what the fault code numbers mean or talk to someone with an OBD 2 scanner!

My 2005 Jeep Liberty CRD has had trouble starting. At first, it wouldn't start when hot. It had a P0402 code which is the EGR. The EGR was apparently stuck open. I had the mechanic replace the EGR at the dealership. However, that didn't solve the no hot start issue. Then the mechanic thought the problem was the air flow sensor was shorted and internally and was causing the computer to go into refuel mode and shut the engine down. So they replaced the mass air flow sensor. But that didn't solve the problem. The dealership also said that there were no codes showing that the crank angle sensor or the fuel system had any problems. Then I took it to a diesel mechanic shop, and the only thing they could think of was that the fuel filter was in need of replacement so they replaced it. But this didn't solve the problem. The diesel mechanic said that the research he did caused him to believe that the vehicle needed the dealership to flash my PCM. They said only the dealership has the ability to do that. So I haven't looked into that yet. But now the car won't start at all. The battery is fine....it turns over real good but just won't start....just like previously when it was hot and wouldn't start. But now it won't start at all. I saw some videos on people who had a similar problem and they found that the ignition actuator switch that had broken was the problem. But I'm not sure yet that that is the problem....because I tried to start the car with the remote start and it turned over but didn't start. So I figured that the ignition actuator problem wasn't the issue since the remote start function probably don't use the ignition actuator to start the vehicle. So I need help figuring out what to do. Can someone please help me?

Hi!

I had a no start problem.
The crankshaft position sensor did not work when the engine got hotter. There were no error codes thrown. Replaced it and no more no start problem.
