rusty 188

Thanks Adam, I will do signal wire to ground later in the week, unfortunately I have to remove headers and starter to excess crank sensor plug. Thanks Richard, I am OPT/Hall sensor trigger settings and I can not find trigger arming threshold tables in this configuration, I think this option is only available in reluctor trigger type settings ??

I have saved a cranking data log and trigger scope, with fuel pump relay removed and the engine is firing and trying to run, sounds like if I fit fuel relay it will run. I will check shields are connected. This is a fresh install LS1 in Porsche 944T running same G4+ and had no issues with Porsche turbo motor. Dyno tuned with no problems, test day at track no problem, issues started at first race meeting, and have gradually got worse.

Trigger scope I did yesterday with engine still, I will do a cranking one later today, Thanks for your help

Ls1 have been having trigger 1 issues which trigger rev limiter at intermittent rev range. Fitted new crank and cam sensor with no change. Both triggers wired to 8v output. Today engine would not start, and with ignition on and not cranking fuel pump was being repetitively triggered and injectors were going crazy. I have attached a data log, any suggestions please.
