Ford F150 wont start

[BMFmike]

Engine will turn over, but it just wont start, it backfired out what seemed like the intake when we tried it yesterday.

I charged the battery since it was getting low and it really sounded like it wanted to start but just wouldnt.

I know there is a lot of info missing, but post with ideas and I will try them out! Thanks

You try starting fluid yet?

If it starts on fluid then you have a fuel delivery problem.. Can you hear the fuel pump click on when you turn the key to the on position?

[BMFmike]

Replaced the Fuel pump, but not the filter, will do that next.

Have taken anything apart to get starter fluid down there, I guess that is next as well.

Are there two relays by the air box(or where it used to be)? One of these relays was the engine management relay and the other dealt specifically with fuel. Fords of that model year were notorious for the plugs and the relays going bad.

Did you pull a spark plug yet? Check one to see if it's fouled. Also check the oil, smell it and see if it smells like fuel.

the truck is probably just pissed it has thornbirds on its feet

brother's 90 is sitting out back with that issue. Very common.

Yupp.

I am betting on a dropped timing chain. the cam gears are nylon and the material crumbles over time. pop the distributor cap and the number one spark plug and see if the rotor points to where #1 is when you bring the piston to top dead center on the compression stroke.

Its an easy fix, they're dealer parts. I had to do it to mine, but I've seen some butcher jobs on wiring harnesses to fix this litte problem.
