Need some FSM help fo 1991 TPI no start
Ok here is the low down-
New 383 with TPI ran for 300-400 miles.. stalled with sputtering and restart/stall- then finally cranks with no start
Ck'ed fuses-ok (incl ECM, INJ 1 and INJ 2)
Ck-ed fuel pressure 39 43-ish
Spark was weak with inline spark tester- (dim) replace org. coil and distributor (reman with new module too)
No injector Pulse with TPI Noid light in #1
I only have a Haynes wirining schematic so here is goes:
Injector driver circuit grounds bank 1 and bank 2 injectors.
