My v10 will not start, the lights blank like the alarm is on

If it is factory then no. If it is aftermarket you can pull the fuses or have the alarm module removed.

Re: 2001 V10 FUEL , MY TRUCK WONT START AND WHEN IT DID...
Yesterday I found the negative cable had fell out of the post terminal. fixed that jumped the battery and got it to start. ran for a while, then shut if off and started again this shortly after. started fine. woke up this morning to the same problem. tried to jump. interior light won't even illuminate with jumper cables hooked up

It looks like your theft deterrent processor needs to be re-programmed. I think the dealer has to do it.

Disconnect the battery, have the ignition key turned to the "on" position then reconnect the battery.

Sounds like a bad connection somewhere.
When you get it started, is the alternator charging the battery ?
Do you have 12 or 13 volts at the starter when it will not crank without a jump ?

reset the alarm system then try...

I need a wiring diagram for a 2006 ford truck chassis, triton v10, carrying a hurricane motor home. Lost all power through generator system, no a/c, no microwave, etc.

Look under the dash for a little button that youll push to bypass the alarm. If not one you will need to disconnect the alarm sysem and remove it. It is useless to you anyway without the key pad

Sounds like you have an aftermarket alarm with starter disable. By disconnecting the battery the alarm reset and the defualt setting is usually to set the alarm automatically (active arming). You have three options..
A. If you have the key fob that went with the alarm you can disarm the alarm.
B. If no key fob is available you can disconnect the battery again, turn the ignition key to the on position and reconnect the battery. This usually doesn't allow the alarm to set and allows the car to start.
C. Remove the aftermarket alarm system. This is usually the long term fix i recommend if the fob isn't available. Option B should get you going though.

i have a 201 ford excursion for about 2 weeks i could not get it to start in the mornings it was hesitant and would take about 4 tries before it would start. i took it to the dealer and they said the battery was fine i ended up changing all the spark plugs and ignition coils and now the car wont start at all.. please help if anyone knows what it could possibly be.
