Hello guys,
I've got a real PITA problem here. I'll try to lay out as much information as I can as there are a lot of factors in this issue.
To start, I'll explain what the bike is doing:
1. Bike does not start but cranks strongly (most the time... sometimes the pump will not prime and although the neutral light stays on like it should, when initially turning 'key-on' the oil pressure light doesn't always come on with the check engine light (I understand that check engine light is supposed to go out after a few seconds upon initial 'key on')
2. Intermittently the high beam light on the dash stays on all the time, regardless of the switch position of the high beam switch.
Background on what has been done of the bike the past year:
I was in an accident with the bike April of last year. I hit a guard-rail at about 40 mph in a sharp curve due to debris in the road and "pac-manned" the front rim, broke the front forks and some other minor rash damage. After getting it home, the damage seemed to only be to the suspension and visual aspects of the bike. It started fine and seemed to idle well.
I replaced the forks and wheel/tire and the other cosmetic parts. Due to bike damage, I decided to repair a few other items and upgrade some other parts. I powder-coated the rear side-rails, underside of the bike, crankcase cover and the front housings on the front of the bike. Due to the rocker gaskets leaking, I dropped the motor and replaced the seals, replaced the plugs and drained and filled all my fluids. After talking with 'Octopus', I decided to also install an innovative wide-band kit so I could get my bike custom tuned as he is local to me.
After this, I put the whole bike back together excited to ride and although it seemed to run, it seemed to be running lean. I double checked the plugs and verified they were gapped correctly and okay. I then noticed on one start-up that the pump started to change noises to a harsher sound. I decided to take out the pump assembly and replaced the pump and filter. Upon start-up, pump sounded strong again but bike still seemed to run really lean and some serious popping on decel (more than usual).
I decided to take her around the block and just as I returned the bike to my driveway, it died and would not start. Since then, I have been having the 2 main issues above.
I have replaced/checked the following parts:
1. Fuel pump
2. Verified/cleaned the 2 rear grounds on the side rails (making sure bare metal was exposed) and have a solid ground.
3. Replaced battery
4. Fresh fuel
5. New plugs
6. Checked all connectors in the rear of the bike and the front including the light connectors (corrosion or burnt/melted connectors)
7. All fuses are good
8. Relays have been switched around with no change in condition
9. Diode is installed correctly
10. I have a Race ECU in the bike, and have swapped in the factory original ECU with no change in the condition
11. Inspected the ECU connectors/terminals and no obvious damage found
12. I've removed and inspected the fuse box from the top and bottom and have found no obvious signs of damage, broken or loose wires
I should also note that sometimes, and only sometimes, when pushing on the fuse box, pulled on the rear harness or pushing on the ECU that I can get the pump to prime and bike to crank. I know this sounds like this is obviously where the problem is, but it is very intermittent and could be a fluke occurrence.
I realize that I will need to start getting deeper into the problem this next weekend by beginning to try to understand the wiring better and do some basic Ohm checks and voltage drop tests, but I wanted to run it by you guys and see what you think. Also, it would be great if anybody on here can confirm where some other major ground points are on the bike.... pictures would be super helpful.
I appreciate any help you guys can provide.
