4ZD1 EFI - Injectors cutting out

Unread post by sudso » March 14th, 2011, 2:39 pm

Father in laws 89 Rodeo has a 2.6 4ZD1 EFI motor and the injectors cut out at regular intervals over 1500 rpm when it feels like it.
Have checked a couple of the injectors with a noid light to confirm it.
I've got a workshop manual but it only covers the carby model so it's of no use.

Just wondering if anyone has had the same problem and what the fault was eg: ECM or crank angle sensor, intermittent short etc......................
Cheers, Sudso
