engine won't crank
No Crank
<HR style="BACKGROUND-COLOR: #271507; COLOR: #271507" SIZE=1><!-- / icon and title --><!-- message -->Hey my 2000 Excursion 7.3 PSD doesn't want to start. I turn the key and the dash lights up everything sounds normal, lights all work. I go to start it and nothing happens. it won't crank over. I checked all battery connections they're clean and tight, batteries are new as of Nov/09. I got the truck to start by jumpering the solenoid on the PS fender and brought the truck home, so I don't think it's the starter. It was working fine until this afternoon. Sounds like the starter is not getting the signal to start. Does anyone have any suggestions?

You'll need a friend and a volt meter. Have a friend turn the key while you are checking the voltage at the starter solenoid. If you get battery voltage at the postive side of the solenoid when the key is turned to start, the switch is fine. In a perfect world, the positive side of the solenoid should read battery voltage and the ground side zero.
If the positive side reads smaller than battery voltage (by a few volts), the problem is between the battery and solenoid. Which usually is a bad connection or switch.
If the ground side does not read zero, the problem is the ground.
Take a few readings and let us know what you get.

Got home from work and pulled off the small wire on the starter relay on the \p\s fender to test for voltage, found 13-14v when the key was in the on position. put the lead back on the terminal, and just for the heck of it, \i tried starting the truck and it fired right up. Could it be just a dirty connection? Or a short somewhere?
