Hey everyone my 750 brute want fire i purchased a ECU and the new used ecu only gives me 5v to the coil and tip over switch the old ecu gives me 12v to the coils and (0) at the tip over switch and fuel pump want run could it be I have 2 bad ecu or something else but the one with 5v going across...
I bought a non running brute turns out it was the fuel pump relay so I jumped it and it cranked right up. I was using a lawnmower battery for testing got it to run awesome had plenty of power so I went out and bought a battery dropped it in and filled it up now it’ll crank up with no problem but...
Here's the deal;
2007 750 brute force
2nd 3rd hand (dunno)
Had it running when I bought it but it would backfire crazy, I seafoamed it with a whole can and a full tank thinking that would clean out the carbs.
I trailered it, wouldn't start.
