Need Help! My daily driver an 05’ Liberty CRD is not running. Towed to shop and it sat for 4 weeks. Replaced Camshaft Position Sensor with no change. Verified no loose plugs etc. Ended up towing her back home. She has also had the Crankshaft Position Sensor replaced a few months back. Sometimes it starts and runs great, most times it does not. She is getting fuel. The Parker Racor R25S fuel filter bowel was drained even though it did not look like any water visable. New battery and charger verifies full charge. No OBD codes. She turns over great but will not start. When she starts there are no issues of hesitation etc. End of rope, need ideas.

It was suggested I have air in fuel line. when I drained the bowel on the bottom of the Parker Racor R25S fuel filter a little of air was bled out. Suggested that I bleed from the injector. If I bled from fuel filter and it has a return line back to the tank would any air circulate back to the tank? I've found no mention of bleeding other then at the filter. Am I missing something?
