WOW...400,000 hits!! As usual if its one problem there's another to go with it. We did go to another dyno shop but engine was acting up [just not sounding right] so we went back to the shop. Two valve adjusters had come loose [ thought I had tighten them good but must not have] bent a pushrod and damaged an adjuster. Replaced them, started engine at night in shop, which was a first, roll up doors opened though, blue flames 3 ft long out of headers except for # 2 which was not firing. Problem traced
to short in wiring connection in EFI, no electric signal no fuel.
The injector wire harness from both sides of engine connect to main harness with a short Y harness. We tested for continuity on each wire and checked for shorting in all the other connections at same time. All tested good until connecting the Y. then shorts across connector plugs showed up.
Will probably end up sending harnesses to F.A.S.T EFI.
