Intermittent no start condition

John....It sounds to me as I said before.....You have an intermittent wire connection problem between the ECU and your MSD or possibly your battery connections to your ECU.

It has been to long for me to recall the exact wiring connections needed between the MSD and the Accel ECU.....

Accel still shows the wiring diagrams and tons of info on their website.

The ignition connector on the Accel unit and all the connections related to it are where I believe your trouble may be. Your ECU needs to be switched on and also gets a tach signal from the MSD....

Without actually seeing your car and wiring it's impossible to tell you how to fix it.

You have isolated the problem and now know it IS the injectors are not turning on and supplying fuel to the engine......so the ignition system is not the problem.....
