Cranking but won't spark
Hello,
I've got a '92 1.6 running a MP45 Supercharger. It recently stopped running,after changing the spark plugs,ignition leads,ignition coil,cam angle sensor and ignitor pack it still wouldn't run on all cylinders. Checked the injector pulse and found that injectors 2 and 4 were open. Opened up the ECU and found what looked like a driver had burnt out. So i changed the jumpers so it worked on Sequential firing and also moved the wire on the ECU harness.
It now won't run at all. I've done a spark test and each plug/lead sparks. I've also swapped back the CAS,aswell as moving the CAS to see if it changes. I've swapped the Fuel Inj relay too from my daily and still no change.
All the wires on the ECU and on the Coil/CAS look good,i've also cleaned up the earth next to the CAS. I could get it running before but now it cranks but it wont fire up.
I've attached the map and a short log
Many Thanks
Chris

Abit of an update
Received the ECU back with the injector driver replaced and i've reconnected the wire on the ECU loom.
Battery charged back up again and still nothing.
The car will spark in the test mode via Tuner Studio but it won't spark while cranking.
I've got a replacement engine sourced,will be getting the swapped at some point as i think the current engine is knackered anyway

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!
