I have a FAST SEFI with ICC in my 97 Cobra twin turbo, running with an OEM crank trigger (36-1 wheel and OEM inductive cam sensor) with a FORD EDIS-8 module and an MSD DIS-4.
Problem is when I recently got my ECU back from being upgraded by FAST my car wouldn't fire right away, but would just crank and crank without firing, and all the while I wouldn't see any injector activity on the dashboard either. I reversed the polarity on the cam sensor after checking over all the wiring a number of times, and it fired up right away and so I assumed that it was a polarity of the cam sensor issue. This however is contrary to what the Lance at FAST told me (he said that with the OEM cam sensor it shouldn't make a difference what polarity it's in as I wouldn't see it on the dashboard anyhow).
I went to fire it up today and it wouldn't fire but eventually did. I had to crank it a number of times and cycle the key at least 8-10 times, and then rechecked all the major connections and then did it some more and low and behold it finally came to life, but without my changing anything or noticing anything out of the ordinary. Idled and ran fine, and then I shut it off and started it again no problem. I left if for a while and came back to fire it up again and the same problem occurred (cranked it a number of times probably 8 separate cycles and it finally fired). The plugs, wires and ignition components are all brand new, and so I'm not even suspecting any of the major players. Fuel pressure, battery voltage at 14.4 and all other criticals all seem normal.
Seems odd that this is the first time I've ever encountered this problem, and so I'm wondering if it's symptomatic of it being set up as SEFI running a FORD EDIS-8 module and OEM crank and cam signal? Perhaps the FAST only likes reading those in a B2B environment? Is it possible that the ECU is random sequential because it doesn't recognize cylinder #1's signal and so #1 doesn't occur as the true #1 in sequence and so until the firing order gets close after cycling the key a number of times, it will finally fire..? Is anybody running a "waste spark" ignition system with an OEM crank and cam signal with an EDIS-8 module? Please chime in with any advice or thoughts... I'm going to go over every connection again and if the problem persists I'm going to have to send it on a trip down south again...
Thanks,
