Only sparks once?!
 

So I changed my oil last night and installed a turbo timer (save the flaming about useless turbo timers haha) now it turns over but doesn't fire.

Checked all connections under the hood/pulled the UI and double checked everything seems good there, under the steering wheel I can't find any issues put it back to no turbo timer and same issue. I've fouled the plugs a couple times but cleaned and I'm only getting spark when I turn the key on, not a continuous spark each cycle.

It's a 93 fd, street port, rotary works intake mani, single turbo setup and all the other usual mods.

Any ideas?!? Getting desperate and very annoyed

no signal from ecu to coils

or you are earthing the coil with whatever wire you attached the turbo timer with and you only get a spark when you turn off the 12v

So you think change the power and ground I'm using for my turbo timer? I was using a 12v off my deck. I did bolt my eft
To the chassis (using the correct bracket) it's an adaptronic ECU I was careful not to hurt any wires.

remove turbo timer and reverse what you have done

either you have interrupted power to the adaptronic or the signal to the coils

or the turbo timer ....or the ignitor ....in someway is holding a coil earthed

and you see the spark when you kill the circuit ( proves coil has 12v at least some of the time )

you may need to check to see if coil drops out to zero volts in the key on position
( ie.. only has volts while cranking .. maybe proving it is in the turbo timer hookup )

by the way
that coil and the ignitor may be getting hot

I only see a spark when I start to turn it over like the first revolution of the rotor there is a spark. Going to change the wiring I did and retry right now

Update: changed plugs, and moved my ecu back to where i had it originally and it seems 3 of the 8 plugs i had were bad despite looking A-1. plug wires were rough as well so i swapped out 2 of the bad ones. may have gotten a little oil heavy on the premix (100:1) and seemed to be tough on the plugs.

cars running now and I'm going to see what it does with the turbo timer installed again, doubt that was my issue but id like to be certain.
