Hey all, new Ranger owner here. I'm not all that UP on vehicles electronics.
I think the cam chain has jumped time but with all the electronics one vehicles these days, on the road diagnosis just not simple anymore.
QUESTION IS... Is the more than timing chain & Cam Sync that would make the engine sound like timing is off?
.
SITUATION:
From a stoplight, normal acceleration, 200 ft later engine quits without any odd sounds. Attempted to restart, nothing. Popped the hood, pulled a plug wire noticed there was no spark. Walked for parts, Coil Pack and Crank Sensor. Changed the CS, got orange spark. Changed the CP, nice blue spark. Now the engine has that distinctive action a timing chain is off a couple teeth. Cranking, turns over 1 or 2 revolutions then abruptly stops. No backfire, just stops.
It has good spark and fuel pressure.
Top dead centered the harmonic balancer. Popped the cam sync cap and the TAB is in it's proper place, tight (not wiggling) and shaft is centered.
.
NOW that it's getting warm enough to work under the shade tree, I'd like this truck running.
Original owner took care of it up to 145K, now 180K (LOTS of receipts).
