no power-batteries are charged...

[bcombs]

new at this hope im posting properly-need help with 2001 7.3-

-recently has been cranking slow-batteries are charged and less than a year old.
yesterday the truck started, ran for about a minute and died- turned the key and it would not crank. the chime and dash lights come on when the key is cycled like everthing is good, but then everything goes out. when the key is turned to off the pcm relay in the dash panel clicks and the lights in the cab flash (dome, dash, door lights) until the pcm relay is removed...tried a new pcm relay-and nothing changed.

two other small problems-the truck is 500 miles away and with my son at school -so i have to walk him thru any repairs...

any ideas would be appreciated.

Is it raining or has it been raining on the truck?
And has the camshaft position sensor been replaced?

Where's he at? If he's close, I'd be more than happy to give him a hand.

not to much rain and yes the cam sensor has been replaced-
he is in central florida-

could be the starter.

I had a bad cable from the starter to the starter solenoid. It would crank sometimes , sometimes slow, sometimes just click . The OHM reading on the cable was 4 ohms and the cable across the radiator to the other battery was 2 ohms. I went to a welding supply shop and they made up a 1/0 cable with the crimped ends, installed it in 20 minutes. Cranks like new , cost about $27

The way I tested the cable was to take a set of jumper cables and connect one end to the starter and the other end to the relay . Cranked over like it was new .

ill check the starter and wires-

the flashing lights thing is kinda wierd-could that just be a byproduct of a short or bad starter??
thanks for your imput
