Question about 1997 Chevrolet Tahoe
Hi Bob , do you have any lights lit on the instrument cluster ? Check engine , Security etc.. Pull a plug wire an see if there is spark , hold plug wire end near metal on engine ! If there is spark spray carburetor cleaner in the throttle plate an see if it try's to start ! There is no resistor in the key on your model !
The design of the passlock?"¢ system is to prevent vehicle theft by disabling the engine unless the passlock?"¢ lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the passkey system. However, the passlock?"¢ eliminates the need for a key mounted resistor pellet. The components of the system are as follows:
The ignition lock cylinder
The ignition switch
The passlock?"¢ sensor
The EVO/Passlock?"¢ module
The security indicator
The vehicle/powertrain control module (VCM/PCM)
The ignition lock cylinder is located at the upper right side of the steering column. The Passlock?"¢ sensor is in the steering column. The Passlock?"¢ sensor is separate from the key and lock cylinder. The key and the lock cylinder work together in order to determine if the proper ignition key was used to start the vehicle.

First check with your GM dealership ,they have recall on ignition key ,based on your vin# you may get lucky,
but if not here what you star with
there is a resistor in your key(people call it chip,but it is nothing but a resistor to complete the circuit) clean both side with alcohol wipe,also check make sure there are resistance from one side to other,if it is open you need new key
here are values,yours are one of these
Check the fuel pump relay first, take it out and check the pins. If they are discolored at all, I would replace it. You can clean up those pins and try it, and make sure the female spring clips are tight too.
There is a hot wire straight to the pump but it's usually a real PITA to find. It's in the big harness leaving the under hood fuses, running under the brake booster.
next you check fuel pressure make sure,pump is working correctly
with key on/engine off should read 60 to 65 psi,with engine running about 55,next as engine running take the vacuum line off the fuel pressure regulator,and pressure should go up to 60 to 65,if not regulator is bad,also check inside the vacuum line and regulator if it is wet or gas present that means diaphragm in regulator is ruptured ,it is also bad,need to be changed,BUT BEFORE CHANGING PUMP.CHANGE THE FILTER ,SEE IF THAT BRING BACK THE PRESSURE UP, if all good then you need to check for spark
let me know and I can help you more
