Get rid of the old fuel. Drain and inspect the fuel tank including the gas tank filter. If the fuel tank is free from debris and clean, put some fresh fuel in the tank. Leave the old fuel filter for the meantime and replace after you have purged the system.
Do not attempt to start the engine until you have completed a fuel pressure test. Why? There could be a fuel leak and you don’t know that. Test the fuel pump without running the motor. If you know how to test run the FP that’s great. If you don’t know the procedure, simply ask.
Before attempting to start the car, check the following:
- Engine oil level.
- A fully charged battery.
- Test for presence of strong ignition signal.
- Turn the motor by hand and make sure it is not seized.
- Inspect the spark plugs and plug wires.
- Etc.
Disable the ignition by unplugging the connector to the CDI, pull out the RED fuel pump relay, and crank the starter very briefly for a short test and stop. Engine sound OK? Keep turning the engine until oil pressure registers on the gauge. Do this a couple of times. If the engine sounds normal, connect the ignition system and plug back the FP relay. You are now ready start the motor. Wish you the best. Keep us posted.
