Hello all,

Just a yami tech trying to work on a bombardier here... :rolleyes:

A friend of mine, owns an '05 RXT and she brought it to me with a no crank/start problem.

First off, the battery was beat dead. Started with a fresh battery. With the lanyard inserted, the standard single beep sounds .. followed by the heartbeat beep reminding me the lanyard is inserted

Pressing down on the start/stop button IS in fact firing the fuel pump, however it is not engaging the starter solenoid. I have checked ALL fuses, including the standalone fuses on the harness. Clean connections on all cables and confirmed 12v to the solenoid. The engine WILL crank if i jump the solenoid, i have yet to feed 12v to the brown wire- dont want to cause more chaos than what ive already got.

I have un plugged the the 2 pin terminal at the solenoid- when you insert the lanyard it seems to determine that is unplugged as i get a second beep that sounds. Anyhow, the purple wire has 12v, and brown has 0 regardless of if you press the start/stop button or not.

Using a jump switch i decided to check for spark- it does in fact have spark.. but even when cranking, it does not attempt to fire. Plugs are dry... something is definitely holding back fuel, and i would assume its the same thing that is keeping it from cranking.

Any advice would be much appreciated, i dont have a BRP cable or software to go with it unfortunately.. so im stuck playing with meters, gauges and test lights. Please any advice is appreciated!
 
You cannot use a key not married to the machine , even if your'e getting the engine to turn over by jumping, it won't fire up if the ECU is not getting everything it needs to say go. Have you checked all of the fuses?
 
Anything with a magnet will activate the fuel pump but you need a paired key to send the proper DESS code for a start. You can jump anything but you will not get any firing of any injectors.

You need the proper key.
