m7 won't start

[sulieman]

I bought 2 2006 M7s ,long tracks. one I installed Boondockers box, jaws pipes and can,changed both clutch springs,and weights, mountainfit hood ,and Boss seat, 4inch risers.

I've exchanged the following parts to help diagnose the problem ,fuel rail , EFI box,stator,

one problem I see is when I put a DC voltmeter on the red and black wire going into the tank it reads somewhere around 4volts whereas my other sled reads upwardsof 12 volts when I pull the cord. I,ve hooked up a 12 volt battery charger to the pump and it pumps very well (lot of Gas).any suggestions???

Unplug the tail light wires on the right side just under the corner of the fuel tank above the brake rotor. The tail light wires have been known to ground out under the tunnel or by the rear heat exchanger.

That sounds like a major undertaking, how long did it take you?
