    Check for spark, power at coil ect. see if fuel is coming out the return line to be sure it getting pressure, that works unless the fuel pressure regulator has packed it in. will it start on aero start ect. Check a few things and get back to us

    I'll check for spark tonight is the return valve at the end of the injector pipe with the value that looks like a car tyre one? Coz I pressed that and fuel squirted out

    I'd check the tachometric relay in the fuse box. Well not sure how to check it, maybe just borrow one off someone and see if that fixes it.
