I dont know for certain if everything else was tested with the ECU,Reverant has been abit vague with the repair carried out.

The CAS was purchased from a breaker,but i swapped it back to the original that was on the engine. The ignitor unit and coil pack were swapped from my running daily driver. The current coil pack on the daily is the one from the purple car,and i've had no issues

How does Tuner Studio test mode get the car to spark, ie what components is it using in test mode?

So after almost 3 months of trying to fix the car i gave in and dropped it off to H&S Performance for them to look at it. Within 20 minutes they had it running.

Y'know how you kick yourself over something ridiculously simple/stupid? Yeah i'm doing that...alot!

Fuel lines were opposite way round on the fuel rail. The fuel pump wiring was earthing out too. So add those to the damaged injector driver on the Megasquirt and there we have it!

They're gonna do an oil and filter change and run it round the block to make sure its all ok.

Easy mistake to make,you live and learn!

I would never had guessed the fuel lines as you had not mentioned removing them.

Am glad you've got it sorted though.

Ha ha, I did the same recently. After putting the head back on. On the NA6 they cross over. NA8 they don't

Nice work. .
