I fixed this problem on mine for .99cents.
1. measure resistance (ohm)across pellit on key
2. go to radio shack and by resistor that matches resistance on key (mine was 11.87 so i bought a 12)
3. orange wire under steering column with two white wires in it. cut it
4. solder resistor in place connecting two white wires on the wire side coming from the car(not steering wheel).
5. any questions email me

How do I start crv after antitheft is activated?

Place the key in the ignition, and turn it slightly to the right. Don't try to start it. When you turn the key the dash lights should have lit up. Keep the key that way for ten minutes, maybe a little more. The theft system light should turn off, and the car can be started.

1997 seville not getting enough gas to start

For the backfiring, there is a chemical additive process for cleaning the intake system of Northstar V-8's. This is suppose to be done at a Dealer and the solvent stays inside the engine 8 hours or more. It is rumored to be written as a service procedure in the Owners Manual.

Check your battery. A shorting battery will activate the antitheft system. Try a new fuelpump Relay

Alarm causes not start

These early 90's vehicles had alot of problems with the antitheft systems. When they fail, they actually cut power to the starter or injectors. Look for a light on the dash that says SECURITY or ANTITHEFT. You see this light, go to this link for answers.

I have a 95 cadillac eldorado starter is good but in car just clicks tryed to jump will not start

Alot of the time, "no start" situations can be traced back to the antitheft system. Especially in GM vehicles like your Cadillac. When this system fails, the antitheft system doesn't get the proper signal from your key. This puts they car into antitheft mode and turns off the starter to prevent theft. This may be your problem and worth looking into. Here iss a link that explains all about it.

Lookfor a light on the dash that says SECURITY or ANTITHEFT. If you see this light, that is a sign of a failed or failing antitheft system, which will disable your vehicle. This link explains

My mechanic says that the reason why my 1997 jeep grand cherokee will start an stay on for only 10 seconds is because i need to have the dealership unlock the anti theft system

I find that to be doubtful but would contact the dealer about how exactly that antitheft system works. In most antitheft systems the vehicle will start at all, or even turn over like it may try to start. If it runs but dies out I would be looking at something more like vacuum leaks, timing, idle air control or possibly the alternator though that seems unlikely.

check theft system for problems with program(dealer)..disconnect battery for about five minutes,reconnect and try to start,if starts and then stalls leave key on for ten minutes exactly...then turn key to off position for 15 seconds..then start...if starts allow to run for ten minutes..
