Machine sat and had multiple rodent chews thru out the wiring that we fixed. Also replaced the Following: ECU, Coil and Plug Wire, small Control Box that contains fuses and relays. Pick Up coil test at 219 ohms which is typically good on most machines but i can't find the specific manual on this thing to get the spec. Battery good, cranks fine but the fuel pump doesn't prime or run and no spark. Tested pump with direct 12volts and it works. If we supply a ground to the pump it primes and works but still no spark. We have traced all wiring including grounding and all is good. Tested key switch. I has (4) positions. 1 - off, 2 - does nothing, 3 - powers up everything (lighting and odometer and powers ECU, 4 - starts engine. The key switch only has 3 wires. 12v in from battery and 2 - 12v out which is power to the system and send 12v to starter relay coil.
Are these electrical systems actually switching the grounds on and off vs the traditional switching the 12v+ on and off.
at my wits end with this thing.
Also when we figure this problem out we will post the solution. seems 90% of people that ask for help on these forums, never post the fix which make this pointless.
Purchased it used a week ago. Found that it wont start from key but will start if solenoid jumped. Also noticed that brake lights don't work checked switch and its working, may be the no start problem from key.
Turn signals and hazards do not work headlights tail lights and hi beams all work.
have a manual but it is hard to decipher.
Hoping that someone has run into these issues and can point me in the right direction with the lights. I believe if i can get brake lights to work it may solve starting from key issue.

Hello. I purchased this unit as a "non runner" with the intent of using the frame to build a go-cart, but once I got it home it seemed way to good to part out. The motor cranks over, and I have spark, but no fuel. If I put a little fuel in the cylinder it fires up until that fuel is burnt, then of course it dies. The fuel pump is not running and I have removed the plug and there is no power going to it. I have checked the safety switch on the brake pedal and its fine, I have checked the fuses, all good, but am not sure where to go from here. The shifter is missing on the unit, but the indicator light on the dash shows its in neutral, and the e-brake indicator switch is working as well. I am thinking of jumping power to the fuel pump next to see if it runs and if the motor will start.
What am I missing? What can stop the fuel pump from getting power to it?
I have a bulldog i bought from home depot in 2013. In the last season it started refusing to shift from neutral to either forward or reverse. I changed the trans axle fluid and made sure the cables were lubricated and free. With a lot of coaxing, I can sometimes get it to shift. once I start driving it, things improve until I let it set awhile. Any suggestion on where to go from here?
