I didn't recheck the fuel filter, though I could smell fuel during the attempts of starting. Will have a look at the filter again. If it's blocked again, my tank must be majorly contaminated!

In saying that, if it was fuel related, the car would have the symptoms regardless of ECU change. The fact that it starts after ECU swaps got me stumped...maybe it was just coincidence :?

In either case...car is going to be parted out...just giving me headaches :(



i don't know if same symptoms but just "kinda" sounded like it :roll:

and that should have been fuel rail/injectors .. not inlet

Yeah I get what you mean and thank you. I will have a geezer at both once I get some more time :).

Pulled the camshaft out and even after 350,000km, it looks clean under the rocker! Okay I cheat, the engine probably had only done 180,000km since I did the head.

Well an update.

Replaced the cam with the stock XR6 cam and put everything back together after a few dramas. Car started first go, went for a drive around the block and everything was okay.

Will try again tomorrow and the day after, however the car has been sitting in the garage, so not as cold.

This issue has only been going on since the cold weather, so it could definitely be temp related.

What data input does the ECU need to start the car? Temp/Smartlock/etc? Would be good to know if any of the sensors could playing havoc with the start up. By trying 3 different ECUs, it obviously isn't the ECU and after a few attempts of starting by swapping out ECUs, the car would have warmed up a little with each kick so would run fine. Could a loose exhaust manifold cause starting issues?

Only multimeter unfortunately. I could possibly get my hands on a few other items.

Did you leave ignition on for approx 30 min after swapping ecu or does replacement have j3 chip as well .
is smartlock light going out .
does interior light work
Possible ecu relay
Can you hear fuel pump when key switched on
