7.3L NO START

[CARLFLORA]

I HAVE A 2000 F-250 7.3. IT HAD A LEAK AROUND THE FILTER DRAIN VALVE THAT I WAITED ABOUT A 2 MONTHS TO REPLACE, SO ALOT OF DIESEL WAS LEAKING OUT ON THE ENGINE. I WENT TO START IT ONE MORNING AND IT WAS DEAD. IT WOULDN'T EVEN TURN OVER. I REPLACE BOTH BATTERIES AND IT STARTED UP, I DROVE IT AND PARKED IT, WHEN I TRIED TO START IT THE NEXT DAY IT WAS DEAD AGAIN. I REPLACE THE CPS AND IT FIRED AGAIN. THE NEXT DAY, SAME PROBLEM NO CRANK. SOME DAYS IT STARTS, SOME DAYS IT DOESN'T. I AM WONDERING IF THE THE DIESEL LEAK CAUSED AN ELECTICAL PROBLEM. I AM LOST!!! I NEED HELP!!!

It shouldn't have! Sounds like you have an electrical draw somewhere. The drain valve in the back of the fuel filter housing doesn't have any electrical under it, and the alternator is too high to be affected by it. Have you checked for codes?

[CARLFLORA]

HAVEN'T CHECKED CODES YET. I CAN'T GET IT TO A SHOP. ANY RECOMMENDATIONS FOR A CODE READER

THE DIESEL LEAK MANAGED TO RUN DOWN MY STARTER CABLE, AND ON TO MY STARTER, WOULD THAT BE CAUSING A SHORT?

[silverF250]

I would say that is possible, but without knowing what the truck sounds like trying to start it I don't know. Just a thought but could it have to deal with the glow plugs relay.

[CARLFLORA]

THERE IS NO SOUND, THE TRUCK WON'T EVEN TURN OVER.

I would say no because it's made to be driven in incliment weather. I'm trying to figure out how the diesel got down to your starter cable...

unhook the batteries, and charge them one at a time if you have a battery charger. Then when the batteries are unhooked crawl under and clean the connetions at the starter (you may have to remove it from the starter) put the batteries in and see what happens.

I would charge the batteries and look for the draw. Make sure everything is turned off in the truck and disconnect one of the battery cables. put one end of a test light on the battery post and the other to the cable. If a draw is present, it will light up. Then you just have to pull fuses and unhook wires until it goes out. That will lead you to it.

That's a good trick right there!

I WILL GIVE THAT A TRY. I WILL LET YOU KNOW WHAT HAPPENS.
