Triton v6 keeps turning off

Unread post by Grass hopper » February 16th, 2015, 2:45 pm

Hi guys

I'm new to the forum but am desperately needing help.
My sons 3.0l v6 runs like a train but will suddenly turn off while driving. Could run for 10 min or an hour then just stops. Sometimes it will start again other times it won't start for several hours?
Taco stopped but traced to a faulty ignition module, working ok but not putting out taco pulse.
Replaced crank angle sensor and swapped ecu but still have this intermittent problem.
We now know all the local tow truck drivers by name ;-(
This model has no immobiliser.
The ecu and fuel pump relays drop out when it switches off.
I have run out of ideas and could really do with some help
Thanks in advance

Cheers

Pete

Have you checked the earthing in the cabin?

I think you need correct earth in the cabin for the ignition to work properly, and If it doesn't than you can have trouble starting and the engine cut at unusual times (in hot weather or when being tossed around).

Just a thought. I fixed up the dodgy one at my interior fuse box and issues seemed to go away.

If you can see that the ECU and fuel relays loose power, it should be pretty simple to trace back to where the power is being lost from. Either Igniton relay, Ignition switch or some loose wire, such as earths as suggested. Just get a test light next time it does it and start tracing.

Thanks for your help guys.
I found a couple of corroded connections and the new crank angle sensor appears to be faulty.
