If code 53 involves the PASS system for your car, the chip in the key has failed, or the sensor in the lock cylinder, or the control module. The anti-theft system disables the starter and the fuel injectors. You could bypass those circuits to get the car started.
This is a common problem on GM cars and trucks. This is caused by a failure in the antitheft security system. What most people dont know is that aside from the key turning the ignition to start the car, there is a whole other part of that key that regulates the anti theft system. Im assuming your key has a small black PELLET in the shaft.
This pellet is actually a resister that reads a certain OHMS. The igntion has a part that reads this resistance. If the resistance is wrong (normally due to wear on the key) the car will go into antitheft mode and not start. The problem is that there are many aspects to this system other than just the key. If the ignition OHMS reader is not funtioning, your car will shut down. After the ignition reads the ohms, it sends that info to the TDM (Theft Deterrent Module) which then converts this signal to another signal that is sent to the starter and then allows the starter to start. I know it seems like alot, but thats how GM does it and "it is what it is". So if the TDM is bad, that is another reason the car wont start. The hard part is finding out which part is failing. You can spend alot of money switching out parts or taking it to the dealer. (TDM=$600-700) If this is not the route you want to take, there are ways to bypass the system permanentaly. This link should help you. There is also alot of info on this subject along with pictures to help you.
It there is a problem with the dash, there is probably no power to the anti theft module in your ignition. The car is in anti theft mode due to not being able to read your key transponder. Basically if it cant read the key, it thinks its being stolen. Either fix the dash lights, or fully bypass the security. All the security info you need is on here including how to bypass it. http://vatspasslockpasskeysecurityhelp.yolasite.com/
Go around the car to the passenger side and insert the rounded door key in the door and an lock and then unlock it with the key. This should disable the anti-theft system. This also will shut off the horn blowing when the alarm is tripped. This works on all older Cadlillacs. Hope this helps.
check fuse 12 inside the car just below dash on drivers side of dash, otherwise check your connectors make sure they snapped into place. the ones below yhe brake booster. changing the engine shouldn't have effected the anti theft unless you left something unplugged. double check your grounds make sure you didn't leave one off at the firewall on the passengerside firewall. hope this helps.
in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.
I just had this same problem with a '96 . do you have a vats key in your '94? you need to bypass the VATS system. read some of the blogs on this site and it will tell you how to do it. I fixed mine with a $2 resistor from radio shack.
