Hey guys my 1988 f-150 daily driver took a crap the other night. I was driving and hit a decent sized bump in the road. All of a sudden the truck backfired a couple times and bogged down. A buddy towed me off the road and we got it to fire up a couple times but every time it would run rough Then smooth out then run rough again. Every time I put it in great it would stall. Now 3 days later all it does is crank repeatedly and won't fire up no matter how much gas I give it. I can't figure out weather its ignition or fuel delivery. Any suggestions? I really need to get the truck running again. Thanks in advance.
Check the 3 needed items for operation..
Fuel, spark, motion..
it cranks so there's 1
spark @ plugs ??? all 6, if not go backwards towards the cap/rotor
fuel at intake ??? air cleaner off, WFO a couple times should see fuel squirt in the venturi.
