2007 M/C 496 no start

[whitecap36]

Engine starts and dies as soon as the key is released. I’ve tested and know the kill switch and lanyard are not the problem. Also know the ignition switch is supplying battery voltage on purple wire with key in run position.

Im using MEDS software to try and troubleshoot. When I perform the the main power relay test there is no clicking heard or felt. Tried a different relay with no change.

The purple wire to the relay from the ECM shows battery voltage with key off and none with key on, not sure with key on crank position.
two red wires from circuit breaker show battery voltage and red wire to coils show no voltage with key on, forgot to check with key in crank.
Does anyone have the working schematic For the main power relay?


Many thanks

Mike

Hi

100% and without a shadow of a doubt...this is a battery issue.
Tell tale is when
edit. Apologies. Just read it stops when you release the key. Ignore if you read my first post. Good luck
