Hi
Althought its a MH I think this is Ducato issue. Had MH 3.5years with no issues during 10k miles. Two months ago after a 50+mile journey stopped for about 1.5hrs. Went to start but turned over but did not start after many tries. Called breakdown. Said something about fuel temp sensor might be faulty and check when get home, bled air from fuel pipe into filter and did a code reset. It started so we continued and arranged to pickup part ordered over phone. Went to Fiat main dealers but part wrong and diagram did not show part. Continued with holiday without issue. Concluded that the Fuel temp. sensor should not prevent engine starting.
Last week came back from trip round yorkshire and stopped at home to empty out. Went out and hour later to move engine turned over but did not start after repeated tries. No fault lights showing (or glow plug or padlock) when ignition turned on and Autel Maxilink ML329 showed no codes for two modules seen. Mobile mechanic got a COA38 code but did not go further as no access to code info. Assumed no diesel getting through which I confirmed when removing filter-in pipe and no diesel. Pump relay removed and tested ok. Fuel pump power shows 5v but assume thats meter on minimal load. Resistance across the pump power supply was 2ohms so not sure if that is ok.
So not sure if I need to remove fuel pump or take to garage to see if its a bigger problem. Still not sure what COA38 means as internet search returned nothing.
Thanks for any further advice as running out of options and next step could be expensive.
