(Not a Car Question?)

I have a 1987 Ford with a 351w. When I warm the truck up or drive it a while, than turn it off, it won't start. If the battery is fresh it will slowly turn the engine over and than it'll start. Other wise I'm waiting for the engine to cool. I've replaced the battery mulitpule times, 2 starters, reset the distributor thinking that I'd slipping a tooth and the timing was off, a new selinoid.. I've heard a lot about poor quality starters from chain stores but I'm out of guesses.

Optional Information:
1987 Ford F250 351 w

Already Tried:
I've replaced the battery, starter, battery leads, selinoid,

If the starter was bad or defective...wouldn't it give me problems even when the motor is cold? The battery leads would also be somewhat the same type of problem.
The motor will start fine with it is cold.

The starter is under warrenty yet. I'll take it back and buy the better starter. Is there one brand that comes to mind that I should ask for? My dad has a volt meter. I'm sure he knows how but hate to keep bugging him. Feel free to educate me. Thanks for the time and patients.

When you buy the starter buy the better line that they sell the house brand is junk and enough to get by if you are selling some thing and quick.To do a voltage drop test you attach a dvom set to dc volts to the cables.The positve lead goes to the battery negative terminal and the negative lead goes to the other end of the negative cable or the engine block for the negative cable test.Next disable the ignition sytem by unplugging the coil wire and grounding the wire.Next crank the engine over and read the voltage on the meter during cranking if it's more than .3 volts the cable is bad or the connection at one end is bad.The positve cable is checked the same way but you have one from the battery to the solenoid and one from the solenoid to the starter.You should also measure the voltage drop across the solenoid.If you go from the battery positive post to the starter you shouldn't read more than .6 volts max.If you get a high voltage reading you have too much resistance some where and the tests should pinpoint it for you.If this has helped please click on MY accept button.
