Have a issue that no one can figure out. I have called my mechanic and without it there he is out of ideas. I was on a trip and day 1 it ran great, never a hiccup. Went out the next morning, no start. tried everything. Here’s the list of things I tried.
checked plugs for carbon build up and tested spark, both spark.
checked fuel pump, works fine.
drained the fuel and put in new fuel just in case of bad fuel or too much ethanol or something weird.
checked filter, all clean.
checked fuel line by pulling hose off injector rail and turning on pump, all good.
checked spark under compression by leaving plugs in and putting in different plugs and checking, all good.
checked cams thinking maybe one broke after the ride, all good.
checked fuel for water, all good.
bought new plugs just to be sure.
Where it gets weird is even if you spray starting fluid in the box on the throttle bodies, it still doesn’t try and start.
Compression sounds perfectly normal while turning over motor.
I finally got the motor started by holding the pedal to the floor and just cranking on the motor. Very rough start but did smooth out after motor reached about 130*.
After that, it fires right up like nothing was ever wrong. Runs great and has 100% power, ran it all day long. As soon as the motor gets cold again, we have the same start issue again.
Any ideas would be welcome!
I’ll post a video of what it takes to get it started soon.
