Just dragged this from customers house he has put a set of injector seals on himself now it wont run, had scanner on with no faults logged no fuel to injectors and no signal (thats if they should be one ) at injectors noid light plugged in,all fuses ok inertia switch ok, am I correct that these should pick a signal up from cam and crank before it gets a pulse, to kick in injectors

Thanks Stuart
