Howdy i have a 1985 FORD F150 XLT Lariat 302hp 8cly 2wd

has new-sparkplugs,distributor,2 fuel pumps, fuel line, intake air controller.


here is the problem, few days ago my truck would sputter when taking off, and have idle problems, but once i hit the highway it ran like a dream. i was cleaning out the old intake air controller, it would run good for 2days then the problem would come back, so i replaced it with a new one, now the truck wont start, it turns good, but just wont start.

what could be the problem?

ty in advance for your responses!

More info? Got spark? can you hear the fuel pump run for a couple of seconds when you turn the key?

ya the fuel pump runs, when u turn the key its turns real good, like its trying to start but sounds like its just not getting any fuel.....

Give a quick shot of starting fluid into the throttle body. If it starts for a second or to, then yes, you most likely have a fuel problem. If it doesn't start, likely to be spark problem. Ignition control module is a common suspect

Be sure the new IAC electrical plug is seated or no start.
It's needed for starting but once the engine is running, the plug could be removed without stall if there are no other issues. Only thing that results is the idle goes low showing the IAC was working.
Good luck.

just noticed that only 6 of the 8 spark plugs were replaced, could that be a problem as well?

May well be . Especially if plugs knackered or fouled up . Would mean you are trying to start with only 3/4 engine power and throwing everything out of sequence .
