My friend has a 2000 ford f 150 and is having problems starting it.?

The alternator wouldn't have been the problem, I promise. It isn't part of the starting system, you could take it out and run the car for maybe 10 minutes until your battery dies. The starting system consists of the Battery sending voltage to the Starter and creating a rotating force to get the flywheel going. If both of these are good, then it's the connections. They're probably corroding in a not-so visible spot. Any exposed wire is a problem.

Ok I guess you mean that sometimes it cranks and starts, and other times it won't crank(rurr rurr rurr rurr)at all.I'd have someone check the ignition switch and the safety switch on the clutch(not sure if it has one but probably).The safety switch prevents you from cranking until you have the clutch pushed in so the truck doesn't lurch when you crank the engine.

If it doesn't have the safety switch, it may be the ignition.If you know anyone that is handy with things, they can probably run a hot wire from the positive side of the battery to the trigger side of the solenoid.If it cranks every single time by doing this, you know the starter, solenoid, and wiring on that end are in good shape, and you can look to the switch inside.

a million. To all and sundry posting inform you to purchase a Chevy bypass on yahoo and look at "piston slap". GM Mite have a class action Lawsuit on there palms. 2.you have a ninety seven with only approximately 100K How is that low Mileage?! next 365 days your Truck is going to be (according to build date) 10 years previous. 3. Its no longer a motor corporation's difficulty in case you probably did no longer look after the truck of the proprietors in the previous you. those issues ensue.Even to Chevy's.there is no clarification for those bias jerks to knock Ford considering which you with the aid of a Rod. 4. the recent Ford super responsibilities are the toughest automobiles and could be for an prolonged time. I see them come out and in of this shop who've been with the aid of a lot paintings and rancid roading and all they want are ball joints, a water pump or the fundamentals. do no longer think of considering which you had one undesirable adventure with a truck that the how corporation is in charge. 5. i'm ill of writing.........

Won't start or Won' crank?

You change starters solinoids and batterys when it won't crank

Won't start means the starter turns the engine over but the engine won't run on its own.

Can you ask again?

Wont start or won't crank?

i am pretty sure it's either a plugged fuel filter, or your fuel pump is shot.
