Yes.
When you turn the key on.. Hot or Cold... the PCM does a systems Check, unless it gets the right data returns.. from a number of circuits & components, it WON'T Start.
Yer shooting either in to it.. it can't HELP but start.. because of the [explosion] (yes, EXSPLOSION) (not, Detonation) created by pure.. high compression.... and either.
Yer call, but you REALY need to get the GP curcuits verified and working.
Either WILL..... be making holes in things, where there shouldn't be holes. (pistons, gaskets, seals and things)
