that video is an excellent example of a bad CM870, CM871 ecm. they are notorious for that when the ecm gets old (8+ years usually) and/or the crank shaft damper goes bad / gets old. ecm. Its done for.//. it is NOT the wiring.

replace the crank shaft damper while your at it or it will do it again in about 2 years.
