I have 93 J Gr Ch w/ 5.2 ltr eng
I started the other day then turned on the Air and eng died and would not
start again.
I have no spark, replaced rotor and cap ,coil, ohmed pick up sensor looked
good, check auto shut down looked good, have fuel and is getting presssure
to fuel rail.
Rotor does turn so not Time chain,

Any Ideas what else besides PCM/computer, I think might be security
malfunction because it shuts down similarly as when set off as when it
just died. Also new battery and good connection ,
