Looks like there is no signal for the injectors to inject at startup.

Car will turn over, fire but with no injection, not start.

Any thoughts on what would cause/solve this?/

Thanks for any input

 

Low power to the ECU puts it in a limp mode where the injector duty is very low. I ran into this issue after my motor was rebuilt, turned out to be a bad positive battery cable.

Check the power wires, one is I believe blue/green, this should be at battery voltage regardless of key position. There is a bigger black/white wire next to that that should be battery voltage with the key in the "on" position and no less than 9.5V when cranking.

 

Do you have a PFC with commander? is it showing 0 inj duty cycle while cranking?

Check your CAS connectors, and also check the spacing on the magnets to the wheel. Spec is max 1mm, IIRC.

 

Problem Solved -- it was the Control Relay next to the EGI relay.
Replaced and all is back to normal.

thanks
