Hey guys,

I have a 94 750 XI that hasn't been started in a couple years. I went to get it running yesterday and there is no gas getting to the plugs. I also noticed the lights (gas/oil guages) were not lighting up at all. Anyone know if the electrical and fuel pump are on the same wiring? Could that be a problem? Also, should there be compression if there is no spark or gas getting to the cylinders? It is turning over but not starting, with no spark or gas at the cylinder. It has a fresh battery as well.

 

1st of all the fuel pump on this is vaccum operated.May need to prime the pump and carbs by blowing through the return line. 2nd, should have compression when eng is being cranked over. 150psi or better.
If unit has no spark, probably has a bad stator.

 

Pull one of the plugs and lay it against the head. Try starting it to see if you get spark. If so, put a smidgen of gas in the cylinders thru the plug holes. (Puts plugs back in.) If it fires and dies, you know you're not getting gas. If there's no spark, follow the wires until you get a reading on a volt-ohm meter when you try to start it. (If the plugs get too wet with gas, they won't fire.)
If this is a carb model, you may need to clean the jets and bowls; at least drain the bowls. Gas goes bad over time, and definitely won't work if it's turned to varnish. How long has it been sitting?
