How do you bridge-out the anti-theft security system....it keeps kicking in and shutting down the van after starting

You can't. It has an anti-theft device. The days of boosting a car with a couple of wires ended in the 1980s! You have to fix the problem, not find a way around it.

Most security systems will not allow the engine to crank or start.

The remote needs to work if the vehicle originally came with the remote from the factory. It gives off a signal to the ring around the ignition switch to deactivate the alarm.

if anti theft module not communication with scanner or diagnostic hook up then your vehicle will probably not start till thats corrected and clicking sounds like relay from security system opening up and shutting down power for starting system

This sounds like the anti theft security is not getting the info that it needs to allow the van to run. If the dash is messed up, then it might be effecting the way the computer receives the security info and is not allowing it to start. Believe it or not, your key is constantly sending a signal thru your ignition to your Theft deterrent module which ALLOWS your van to stay running. If this has been interupted, the van goes into anti theft mode. Here is a link on how the system works and some Solutions that might get you going again. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Sounds like the PASSLOCK SECURITY SYSTEM is shutting the injectors off.Is the security light blinking off and on?

1st of all Read Your owners Manual, Depending on the Radio you have in it will depend on the Alarm system . Also Completely Disconnecting the Battery Will Reset your Security System

you have to take it to the dealer and get the anti theft module reflashed - most dealers charge around 95.00

did your battery die recently or did you replace the battery?

Anti theft system. You might have a door lock causing the anti theft system to kick in. (thinking its being stolen.)
