Hi Paul - Thanks for the reply. If you have never seen those go bad, then that makes me feel better it might be my EFI relay, good point on testing into and out of the resistors. When I sit there cranking, the tach is jumping, but absolutely no action at the injectors, I triple checked that with a Noid light, lots of hot spark and lots of gas at the injectors too.
To you, does that sound like an EFI relay acting up?
Many thanks- Yasin
