Have a 06 Mustang GT show car that won't start. It is giving a code B2103. I have tried another key, brand new battery, fuel pump reset, and swapping fuel pump relay. It turns over, but will not start. I am leaning toward a possible issue with the crank position sensor. Just want to see if any others had this issue and what it turned out to be.

 

could be the crankshaft position sensor or the fuel rail sensor, both can produce a no start condition.

if it might be flooded, hold the pedal to the floor then turn the engine over for a bit...if flooded, should start within 5 seconds.

Hey Hammy!! Haven't seen you around lately. Hope all is good.

 

B2103 Transceiver internal antenna damaged. Replace transceiver

 

WTF is an internal transceiver antenna?
Is it beside the turbo encabulator or next to the left nostril inhaler? LOL.

 

hello my friend, all is well and good to see you are still active! i rarely log on, but do try to keep up with the forum.

 

No. It's a solar-powered antenna that generates a signal for the vortex generators to activate the lubrication system to the muffler bearings.

Seriously, it looks something like this and is on the ignition lock cylinder. It's part of the anti-theft system (PATS):

 

Thanks Dino. Makes sense - like using a non programmed key.
(I haven't changed my muffler bearing lube oil yet. I'll have to get on that! LOL)

 

While you're at it, replace the synthetic blinker & flasher fluid at the same time. Then you won't have to do it again for another 20k miles.
