I've coverted from mfi to efi on a rs turbo engine using cosworth gear

L6 ecu and wasted spark driver all new sensors, only used parts are coil pack and ignition modules

I'm having the problem that the injectors are not pulsing and I'm not getting spark

All sensor air gaps are at 6thou and afaik aligned correctly

My question is if 1 of the ignition amps or coil was faulty would this stop the injectors pulsing?

As we may be removing the wasted spark driver set up to revert to the distributor as I know my ecu worked that way

Or am I barking up the wrong tree

 

A non read from the crank sensor will lose both fuel and ignition so check this first, a gap of around 0.8mm will be fine, it's not critical, I would also check you defo getting power to ecu first ?
The 12v LIVE for the injectors simply comes from a relay when ecu powers up, so check to see if you have a permanent live at each injector.

cheers tab will check it out, sure ecu is coming on as when the engine is turned over by hand the fuel pump cuts in (ignition on)

 

Found a wiring problem

When I cut back the old coil connections I didn't rejoin the feed for live to ignition modules, thats all sorted now so once my ecu comes back from testing I will hopefully get it running

Would the ecu sense no ignition and stop the injectors pulsing???

 

No, CPS could, it's the Phase sensor that provides the info for sequential fuel injection.
