Hi, so I brought my GTi-6 in 2009 the week in between Christmas and new year in 2009. I come across a unseen big puddle in the dark and hydro locking it bending a conrod. It was rebuild and the head got smashed up in 2010 another head got at the time but life happened got left.

2019 engine rebuild and non starter fuel pump not priming no power at pump. Fuel relay replaced power to the pump still not priming so pump replaced for pump from peugeot. Pump priming, has spark still non starter.

Over the last year things been cylinder compression tests all good. I have two ECU's one eBay brought as unlocked still not starting. Send the cars original ECU to get unlocking as started to question it the one I bought was unlocked. It has a new crank sensor.

Using easy start being spray in the inlet manifold it sounded for a second it nearly started before the fire blow back out of the inlet manifold.

Neither ECU's can be cannot be read by a snap-on zues diagnostic machine.

Does anyone know if a snap-on zues diagnostic machine can read GTi-6 ECU's?

Any ideas welcome on want to look at or try doing. Thinking checking wiring. I know the indicators are working in any way relay changed and hazard switch too.

Thanks for help

Andrew
