Hi

I have a 86 Daytona Turbo z. converted to T2 with 86 GLHS stg 2 LM

Car ran fine for a couple years with this set up. Painted the car and it has sat i my garage for a few years. Note I start it every few months and no issues up to now. Last time I started it was middle of Oct, Note battery is fresh and car cranks fine.

anyhow, I attempted to start but all it does is crank. I dont hear the fuel pump so I checked the pos 12V connector at the coil with the ignition on the run position, no voltage at the coil so no voltage to the pump nor injectors.
If I jumper from battery to the coil + terminal I can hear the pump click.
I swapped a brand new mopar Hall efftect in to rule out the loss of synch signal but that made no difference, still no voltage at the coil (bk with green tracer, splice Z1)

I am going to play with it next week. Will check the LM and the connectors, will check the PM and the connectors and the fusable links, but dont see any thing standing out.

Anyone have any suggestions other than that?

Thanks!

Have you checked the ASD relay for power in / out and signal from the LM? That's what controls the power to both the positive side of the coil and the pump.
