starting problems
My 86 f150 is doing something very strange. It has a 302 motor in it. I only drive it a few times a week max to deliver wood. When you first go to start it up, it starts fine. doesnt crank alot or anything. After you drive somewhere, and get it warmed up, you go to start and it turns over reallly slow. if you keep turning the key on and off, it will eventually pick up and start. What could this be?

I had this happen to me on a mustang I have I replaced it with a remanufactured one and it did the same thing in a month or so. I fixed it by making a heat sheild for the starter out of a piece of sheet metal. The engine was heating up the starter and it did not want to turn. scott

could be the starter, and it also could be the alternator going on you. A good battery will "come back" for lack of a better term if you give in a couple of hours. When it's just been run and the alternator isn't charging very well, the battery will have a little trouble starting the truck. My suggestion is to measure the voltage with a multi-meter before and after starting the truck and see what you get. It should be 12 off, and 14 on, or thereabouts, if anything a little higher than those. If you get lower, say below 13.8, then it's the alternator. If you get the right numbers, then go starter. I only say this because a battery is a little easier to replace.

Once it's all good there, if the problem persists, load test the battery or have it done. If the battery tests good, do a starter draw test. Pulling too many amps? Change the starter. Do it in that order, save money.
