SOURCE: battery light

I would have to say that it is. I would recommend taking it to the nearest auto parts store and having them test the battery and alternator just to be sure it's not just the battery. Hope this helps.

SOURCE: I have an 01 ford f150 i just put a new computer

the theft light is flashing because the ' new ' truck computer does not identify with the key chip.
if you have two keys to the truck you can try one thing --- put one of the keys on the passenger seat ( this keeps the chip away from the ignition ),, put one key into the ignition and turn it to the ON position and wait about 15 seconds,,, turn back to the OFF position and remove the key -- now take the other key and put that into the ignition and turn to ON position and wait 15 seconds,, back to OFF and remove the key,, now place the first key that you started with into the ignition and turn to the ON position and wait and see if the theft light goes out,, if it does not go out - try and put the other key back into the ignition and see if does. IF it does not work then you will need to call a automotive locksmith that has the ford programer and they can come out and re-program your keys to the new computer ( but you have to have two keys to do this ) -- so if you only have one you will need to buy a new program key from the locksmith ( this is not cheap,, but it is necessary to program the trucks keys to the computer --- and it is a lot cheaper to have a locksmith come out to you then to have the truck towed to the dealer and then pay their price for the keys and programing --- the locksmith will charge you 75 to 80 dollars,,,,, the dealer will charge you 150 to 250 dollars ).
$75 dollars is what we charge at the lockshop that I work at in Alaska and it is a fair price.
have a great day,

SOURCE: 2000 ford f150 change computer from junk yard ,

The HEC ( hybird Electronic Cluster ) has a PCM ID stored in it, that needs to be cleared from the old one you had, so the new one can be re-learned.
The HEC sends the valid key tag with the PCM_ID configured in the HEC to the PCM for comparison to know if the start enable should be valid or invalid

This is so someone cannot take a cluster, ignition key cylinder and the PATS keys configured in the HEC, and put it into a truck, to make it start. Takes a bit of programming to get it to work.

Going to need someone to erase the PCM_ID parameter in the HEC to make the truck not think it is being stolen ( good news, it works as advertised ).

Where is the electronic flasher located on a 2003 ford f150

In a flash / relay block to the right of the steering wheel column under the dash. The bloc is black with a black relay and flasher installed, could be covered in tape depending on the manufacturing plant your truck was built at.
You will need a flash light when you go looking for it.

My ford F150 will not start sometimes

When it won't start, is the theft light ( on the dash ) flashing fast ?

The other thing to check is the fuel pump driver module, on the cross member by the spare tire.
Lower the spare tire, and you will have access to it.
Take a look to see if the module has corrosion pushing it in half, could be on the way out for good.
