I have a 2000 Ford F250 7.3 when I slam the hood it will power up but as soon as I plug the key in the truck immediately dies. I tested the battery is good. Please Help stuck in midland if I cant figure this problem out.
Please give a few more details --
Sounds like you 'somehow' get it started when you slam the hood -- are you using your remote?
Then when you put the actual key in it dies. Do I have that right?
If it's a key that works with the anti theft, maybe it's not being recognized. I know almost nothing about those systems, but I would assume that a dealer could check to see if the chip in the key is working.
