fired up the lap top after installing gregg and petriks stuff. "INVALUABLE" immediately told me i had ignition lockout. traced everything back to the diode that comes from the side stand switch. like looking for a needle in the hay stack. some how the wire got pinched just ahead of it. i...
swapped turn signal and fuel pump relays with different ones. fuel pump works when supplied with 12v, ecu powers up, installed it in another 08 busa and ran fine. thinking its got to be a sensor. wiring harness is intact. painstakingly checked every single wire for continuity and it all checks...
have 08 busa and can't get fuel pump to prime. swapped relay and is good. fuel pump good. ecu good. power to all the right places. engine cranks but no fuel or spark. is there a sensor that could be bad that the ecu would then cancel fuel pump ? just guessing, went through the repair manual but...
HI all, i am new to the forum and am certainly impressed. took the plunge and bought an 08 motor for my sand rail. lots to learn. would love to get some input from ya'll. can anyone give me some direction ? i need to make this thing run, and have the stock wiring harness and ecu but no on/off...
yes, that is part of downs engineering rebuild of my stock harness. correct me if i'm wrong, but i don't believe the engine will start if the resistor hasn't been installed.
no, i sent the harness to downs engineering in california and he stripped the harness down to just what i needed for a momentary start/on switch and eliminated the gear position and tip over sensors. i had the engine running many times with the aftermarket fuel pump and regulator. it ran...
the 08 engine is in my mini buggy. it appears that the ecm is damaged and will not energize the fuel pump or provide spark. i believe that it was reflashed before i purchased the engine and wiring harness. the O2 sensor had been taken out of the circuit and replaced with a resistor. i am now...
