Hey folks workin on a efi 1600 na and its sparkin but its sparking first and forth cylinders at the same time and second and third goes at the same time aswell. But first and forth spark 3 times and then second and third spark once! Any help please?

 

what loom you using, if your your using N/A engine you shouldnt use an EFI loom, as this is for injection not N/A

 

it a n/a but a 1600 injection mate its the right loom for the engine

 

1 and 4 then 2 and 3 should spark alternately , I would say you might have a faulty coil , the half that does cyls 2 and 3 , it is breaking down and can only muster 33% of the HT required , as the coil has 1 feed and 2 switched earths , 1 for cyls 1and 4 the other for 2 and 3 , it is sparking at some point so would kinda rule out wiring to some extent ( not completely though )

Try a known good coil first then check wiring continuity back to edis module , then try the edis module itself isthe route i would take .
