Guest cheaprunner Posted June 18, 2008 Posted June 18, 2008 Okay situation is this: Battery is good on starting it turns over fine but no firingdiagnosed the ecu, reports no codestested: fuel pump fineinjector fineidle motor finemanual tested the coil resistances are correct, have a new one and its the same as that...tried it anyhow and didnt make any difference. Could be the spark but theres nothing at all so unlikely to be all of them since it worked the previous week. Only things left i can think off is cleaning the injector oe replace ignition module. Any ones thoughts on this one? Ive checked all the cables seems all connected. Quote

kfk Posted June 21, 2008 Posted June 21, 2008 The white plug under the ecu ussually causes loss of fuel pressure and has no effect on the spark......my guess would be to get the engine speed sensor checked.....a faulty speed sensor wont always give a fault code. Tell us how you get on. Quote

I havent taken it apart but it doesnt look burnt on the outside.... Quote

Tell us how you get on. well the tps is part of the manifold and it says in manual not to remove it, if its knackered its a new throttle body, im wondering if it maybe a leak on the injector o ring...or some wire behind the manifold i hear is a problem getting too hot. Il have a more detailed look later today... Quote
Guest cheaprunner Posted June 22, 2008 Posted June 22, 2008 Okay, heres an update, ballast resistor is okay since the injector fires. Ive tested voltage on the coil on start and its 0v, thats at the relay end, which should be at 12v i take it? It briefly flashes 12v on the ignition setting before starting. So i dont know if its the relay? So only things left it can be is crank position sensor, ignition/injector relay and the ecu itself. Since the ignition controller is in the ecu. None of the other sensors failing will stop it from actually starting up as far as i am aware at least. Quote
