Hello everyone,
I was wondering if anyone knows if the ECU regulates the fuel to the engine while it's running?
There's a problem with the ignition switch. When I turn on the key, the pump does not hum.
I have to make and break the power to the relay for the pump to respond and turn on. (with a jumper wire to battery) After starting, it runs normally but it's receiving constant 12v as it's connected directly to power.
Is there a wire from the ignition switch to the ecu and then one from ecu to fuel pump relay that turns on pump and then turns the pump off and on during running? Or is it just a constant 12v also when working properly? Could that connection be severed somewhere? I did blow the main fuse awhile back and am concerned that I may have caused some other damage somehow.
Could this be why the bike is overheating? Is the pump sending to much fuel to the engine? It wants to stall and backfires often, otherwise, runs ok. Acceleration is very strong.
There is no smoke or steam from the exhaust. I've flushed the coolant system and added Prestone still overheats. I've also removed the thermostat.. runs a bit cooler, but still gets very hot.
The fan is always turning on. Even while moving.
I'm suspecting a leaky head gasket, but as I stated there is no signs of burning coolant, and the level stays the same apparently.
The idle adjustment came clean off for some reason.. i turned it out too far. Now I can't get it back in! It seems to be stuck when I try to screw it in and won't go in very far.. therefore I cannot adjust the idle.. It just idles a bit lower than it normally does and stalls a bit easier, but otherwise idles ok and runs ok.
Thanks in advance for your help!
