| I also am of the thinking that only TPS and timing (CPS) will inhibit starting as when TPS disconnected, no spark. When air temp/press or water temp disconnected, same as before, will not start but fires once or sometimes intermittantly whilst cranking.
Pin push back, pin pull-off check ok today.
Supply to sensors correct at 4.8 to 5V
Output from air press sensor 4.5V... don't know if that correct but seems reasonable.
TPS primary coil 520 ohms, output 60 ohms idle to 600 ohms full throttle with no dead spots.
Water temp sensor 5510 ohms
Air temp sensor 3280 ohms
All resistances measured from ecu. Volts measured at sensors.
Supplies to ecu ok.
All earths ok
Tried independant supply to coil sticks and injectors from pump/injector relay output to ecu body, same result
Tried jury wiring ecu body 38 earth lin (sidestand eng kill) same effect
Injectors resistance 14.8 ohms from ecu
Coil stick resistance 1.7 ohms from ecu
Tried starting with one stick and plug out and comination of plug/stick in one cylinder at a time, confirm same effect and fires both cylinders with any combo once or intermittantly.
Am starting to suspect ecu even though effect is same with both my "racing" ecu and the flashed one (to bypass imobilliser). My original ecu confirmed no ign switching at all.
Insulation checks not done yet, only done so far with multimeter not megger.  |
