Got a really nice 2013 crf450, traded for it as is non running, followed the guy that had the bike and all the stuff he tried and checked. Anyways the bike is fairly modded and will not start. Has great compression and nothing odd.
Bike has spark
Just installed brand new fuel pump with no change.
Checked timing and was off maybe a tooth, has pro circuit camshaft. Fixed timing and no change.
Nothing is blocking airflow in the air box.
He swapped the vortex pcm for a stock one and no change.
He said the injector was spraying when turning over, but I don’t smell fuel and can’t get it to hit a lick. I am leaning towards map,tps, or injector.? I guess it could also be the capacitor or rectifier.
Any simple test or tips to check stuff? I hate to just throw money at it and not fix it.
I ordered a complete throttle body off of eBay that has the injector,map, and tps sensor that I am going to try.
