Not starting?
If not, try this. Turn the key to on. Security light blinking? If yes, let it blink for 10 minutes + it will stop blinking. Remove key, then insert key and start car. Computers went bad on these often.

Where is the starter relay on a 1998 Monte Carlo located


It's not called a starter relay , it's theft deterrent relay and it's controlled by the theft deterrent module.
When the ignition switch is moved to the START position (and the theft deterrent module recognizes the key code), battery voltage is applied to starter solenoid (through the theft deterrent relay). Both solenoid windings are energized. The circuit through the pull-in winding is completed to ground through the starter motor. The windings work together magnetically to pull in and hold the plunger, which moves the shift lever. This action causes the starter drive assembly to rotate as it engages with the flywheel ring gear on the engine. At the same time, the plunger closes the solenoid switch contacts in the starter solenoid. Full battery voltage is applied directly to the starter motor, which cranks the engine.

No. The theft deterrent module creates a signal that allows the starter to start. Without this signal the car will not start. There is a way to bypass the system and replicate that signal. Look at this link under "permanent fix". This is your best complete fix. http://vatspasslockpasskeysecurityhelp.yolasite.com/

the car gets power from the fusible links on the starter. or the fuse box. follow the positive cable if it splits into 2 directions, follow the small lead and inspect any fuses you find.

Starter tested good. i put it back in and still nothing


battery or ignition switch perhaps?

You can jump the starter on the car to confirm it has the juice to crank. Then you need to check the wires out of the starter key switch to see if you have juice coming out. You could also check at the starter relay.

THE PROBLEMS IN YOUR CAR COULD BE A BAD KEY TRY ANOTHER KEY YOUR CAR HAS THE THEFT DETERRENT MODULE SYSTEM BEST TO HAVE CAR SCAN TO CHECK THE THEFT SECURITY MODULE AND THE TRANSMISSION NEUTRAL SAFETY SWITCH IF ITS BAD STARTER WONT WORK.ALSO CHECK THE THEFT DETERRENT MODULE RELAY. BEFORE REMOVING BATTERY CABLES TURN OFF RADIO SO YOU WONT LOSE YOUR RADIO PLAYING CODE.

Yes, the key,ignition, or Theft Deterrent Module is not funtioning properly. You can start changing these out 1 by 1, or bypass the whole system for about the cost of a new key. This link explains and will help you.

1983 Oldsmobile Delta 88 Electrical problem. I AM STUMPED


It goes thru the dash circuits. Yes! add a wire from the alternator output to the plus battery . The charge lite may be inoperative - either on or off. You might want to put a fuse in that new line.
A cheap volt-ohm-meter would help you see if the alternator is charging 14-14.8 volt and the alterantor field is being energized.

1999 oldsmobile delta battery changed but won't power on


If everything else checks out Ok in the ignition system (electrical) and if the engine and transmission turn freely,that sound like you might have starter drag.Check to see if you have good connections at the starter.I know its new but check your battery for 12 volts,good connections,ect.
