Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Sounds like the anti-theft immobilizer is acting up. Is the security indicator warning light on the cluster? If so, do you have another key you can try?
Yes, I am. When you say no codes, do you have access to a wiTECH or equivalent scan tool so we could look at engine data and find out what is preventing the engine from starting? Will it start on starting fluid? If yes, will it keep running once it has started?
OK. What if you fill the filter assembly? Will it start and run until the fuel is depleted? If so, can you rig a steady fuel supply to the filter? If so, and the engine starts and runs, then we need to look at why that transfer pump is not doing its job.
So, even though the filter assembly is full and lift pump is working OK, fuel is still not getting from the filter to the injection pump?
Can your scan tool display actual fuel pressures?
That sounds more like it. So, what might be happening is that fuel pressure is not getting to the rail. The computer opens or closes the FCA to meet whatever the demand is, in this case that demand is 5830 psi. So we need to know what the computer is doing with that FCA. Can your scan tool display that data? - could be displayed at percentage of duty cycle?
Better yet can you force the FCA open with your scan tool and see what kind of pressure we get then?
I think I typed my response a little too late. Are you saying that with the FCA disconnected we are getting default pressure and still the engine won't run or that default pressure is just being displayed but actually not true?
OK. Let's put those readings aside for a moment. Can you force the FCA open with your scan tool and see if the engine will start?
Ahh... In that case I will opt out and let others help you as I don't log on weekends - wife calls it "her time" ;-)
Please don't respond until another expert responds or the site will cycle this back to me and I won't see it until next Monday.
