2002. Why has anti lock cut off ignition and fuel?

Try a another relay from the fuse box, relays do burn out on occasion, this would tell you if it was the relay, hope this helps.

there is some issue with ur anti theft sy.

Most fuel injection systems use a ignition bypass circuit to energize the fuel pump when starting the engine. However, when the engine starts and the ignition key is returned to the "On" position, a Fuel Pump Relay keeps the fuel pump working. The relay may be defective.

You can't bypass the entire system. It has to remain operational, however you can bypass the most common failure item.
could try bypasssing fuel relay You bridge connections on relay if i remember right.

The most common failure in these is the sensor in the ignition lock that reads the key pellet. That would mean replacing the ignition lock with a sensor included.

That sensor can be bypassed. You would need a digital ohmeter to measure the resistance of the pellet in the key. Now go to Radio Shack and buy a resister of the exact same value as the key pellet. Go to the base of the steering column and locate the two thin white wires that go up to the sensor. Cut the two wires and solder the resister between the two ends coming from the harness. This will permanently bypass the sensor but not the rest of the system.

IF FUEL PUMP RELAY IS NOT WORKING THE COMPUTER IS NOT READDING IT THEIR IS NO BYPASSING THE COMPUTER(ie) DOT CODE on that model vehical THE MASS AIR SENSOR REGULATES 90% OF HOW THE IGNITION TIMING RUNS I USED TO GET AWAY WITH IT ON OLDER MODELS NOT ANY MORE!?

Your does not have a fuel cut off, check fuse and relay, more then likely fuel pump or anti-theft.

check to see if the security light or anti theft light flashes. if that is the case, sounds like the bypass for the remote starter may be causeing the no start by tripping the anti theft system. Remove remote starter and bypass system and join any cut wires back together that may be cut for remote starter. Try starting, if theft light still flashes leave key in the on position after attempted start for 15 minutes till theft light goes solid, turn off and try again. Repeat process for three times to re-learn factory theft system in vehicle. If problem still persists, then take to your local dealer to reprogram factory theft module in the cluster.

Ignition coil/coil pack malfunction
Ignition control module malfunction (ECU)
No fuel pressure, malfunctioning fuel pump
Fuel pump relay malfunction
Immobilizer activating cutting fuel and ignition, part of anti-theft feature (a key icon present on dash)

The fuel pump relay won't energize if the ignition is bad, or the fuel safety cut out is bad. Don't know what Dodge uses. Ford has an inertial switch in trunk. Many cars use the alternator. Some use extra wires to the oil pressure sender. Try looking at the wiring diagram on relay side, and jumper the outputs where relay plugs into, bypassing the relay completely. The pump should hum and you should get pressure. If not, make sure the tank isn't buiding up vacuum, and make sure the power and gound are good at the pump.

Do you have a "spark"? test: remove a sparkplu wire from a convenient sparkplug and lay it down on a nearby metal ground. Crank ignition and look for a spark from the end of the cable to the metal ground.

Spark? Then it may be the fuel safety cut-off switch (with a delayed reaction) ... mounted in the back, inside a side panel. It cuts off fuel when it senses a collision.

No Spark? ... ignition relay switch or the cable from starter solenoid, most likely.
