Hello:
Problem: 2005 Jeep Liberty CRD Sport will not start.
Current error codes: P0340 - Camshaft position sensor, P1261 - #1 Glow Plug low circuit, and P1265 - Glow Plug #3 low circuit.
Other symptom: With turbo hose disconnected at intake manifold, There is no intake vacuum when engine is cranked over.
History: Have 2006 Liberty CRD Limited with 73,000 miles. It runs great, no issues. Do all maintenance myself.
Bought this 2005 Liberty CRD Sport on craigslist cheap. Was not running, owner was moving. 253,000 miles. Owner said it was running great, then stalled and never started again. They had mechanic come out and do read error codes and said crankshaft position sensor was bad. They got outrageous repair quote from dealer, so decided to just sell it cheap.
I read error codes and got P0335 - Crankshaft Position Sensor(like they said), and also glow plug errors
Being familiar with cam/crank sensor issues, thought would be easy fix. Bought Jeep and towed it home.
The good: Battery 12.85V, strong cranking, no bad or unusual sound cranking. Overall Jeep engine and wiring is in good shape.
Bad: Does not start.
Troubleshooting done so far:
1. Replace Crankshaft sensor
Result - P0335 went away, new code P0340.
2. Okay, replaced Camshaft sensor and connector. Standard Motors model from Rockauto.
Result: No change.
3. Tested glow plug ohms at connector, verified #1 is bad with 85 ohms and #3 is bad with open circuit. Has Bosch 5V glow plugs. New plugs on order along with ERG elbow gasket kit.
4. Removed top 6 bolts from timing belt cover and marked camshaft pulleys and belt with bright nail polish. Belt looked good, not broken, not loose. Had friend crank over engine while I watched belt and camshaft pulleys
Result: Belt and camshaft pulleys seemed to turn okay turning starting.
5. Had read somewhere on-line hint about spraying WD-40 into intake manifold while cranking. Like using gasoline starter spay in gas engines, but will not blow up diesel engine like the other stuff would. If timing is correct, engine should momentary start. (Would like members advice on this hint) Had friend crank engine and tried spaying very small amount of WD-40 into intake manifold at turbo hose port.
Result: Nothing...That is when noticed that there was totally no intake vacuum pressure at port when cranking.
6. Had friend crank over a few more times while I held hand over intake port.
Result: No intake pressure. At end of 2nd try, the moment engine stopped cranking, there was slight buff of output pressure at port....that was it.
Have searched internet and Jeep forums for advice about having no vacuum pressure at intake manifold while cranking. Have not found anything. Could be using wrong words or wrong issue while searching.
Know ERG system is mixed in with intake air flow and ERG is a bad design that many people bypass or turn off with Green Diesel program. Plan to do that in future.
Would like members advice and suggestions on why there is no intake vacuum pressure.
Thank in advance
