video of no fire

So it just keeps turning and will not fire. I made 2 stops before this one where it died. Had to tow it home. Starter sounds like it works, its brand new, battery test good, sounds like fuel pump is good. So I just replaced the CPS with a new and still won't fire. Any thoughts?

assuming fp and spark; check ALL grounds first. clean all grounded connections. make sure all sensor connectectors are cleaned with electric contact cleaner. then use diaelectric grease on all those connectors. i'm not saying clean the sensors; just the connectors. spray the cleaner then hit it with air. then apply the grease and plug in.etc.

i had this problem a year ago. did all that and the problem went away. i unbolted all the ground points and ground straps. i used emery cloth on all the ground contacts. sanded some of the grounding points to bare metal then reattached, then repainted that area. and put the diaelctric grease on them too. it would at the least, eliminate it as a possible cause.

hope this helps.

Always disconnect the battery before attempting any work on the electrical system.

So not trusting Tire kingdoms "spark" test as that just happens to be where it broke down near and I asked them to look at it. I pulled the coil, pulled a plug and put it in the top and got no spark. Could possibly need a new coil I am guessing. Might pull my buddies to test.
