Yesterday, running fine, parked up, came back to it and nothing, wouldn't fire. Issues were constantly running fuel pump and constantly sparking.

Now, I've removed the ecu cover checked connections. Used my saff L8 and same problem so I'm confident it's not ecu. Fused all ok. All wiring connections are good.

Any other ideas? Car is L8 with Coilpack conversion.

Cheers

 

As the crank sensor triggers spark and enables fuel pump could there be an issue with this or wiring, new one on me though I would have thought internal fault on ecu but you have already tried another one. Hope you sort it easily
