Hi,

Offhand, a lot of possibilities that can cause no spark and/or deteriorating performance.

  • possibilities for no spark:
  1. faulty computer;
  2. if it is an automatic transmission, the neutral switch;
  3. if it has an immobilizer tied to the anti theft/security system;
  4. faulty cam and/or crank position sensors;
  5. loose wiring connectors, corroded terminals.
  • possibilities for deteriorating performance:
  1. major tune-up;
  2. restricted, blocked faulty injectors;
  3. clogged fuel filter;
  4. clogged air filter;
  5. engine age.
The correct procedure would be to have the car's computer scanned for the error codes. The error codes would give us a general idea where to begin diagnosis/tests. There are a number of known shops that would do the scanning for free and provide you with the error codes.

Hope this be of initial help/idea. Pls post back with error codes, how things turned up or should you need additional information. Good luck and kind regards. Thank you for using FixYa.

First look at this and make sure the plug wires are connected correctly. 3e7c3d3.png
If the plug wires are correct then it is obvious that the cam belt was installed incorrectly of a sensor was damaged during the installation. Take it back to the person who replace the belt and nicely demand they fix it.

Car just stopped running. Lost power suddenly.


Find an inductive pickup indicator for spark. Place on distributor cap to see if spark is at coil internal tower. If no spark at internal tower, look at ignition module or pickup coil. Ignition modules are prone to failure on 626's. But if you have spark at tower but not at the wire end, then your rotor is gone.

Engine shudders and dies trying to go from a red light


The engine has an electronic module where the spark plug wires connect to. Replace this and you will see the difference. Once this module heats up it will malfunction. After cooling down the car will start up again. hope this helps.
