2003 lancer oz rally don't start/think its the fuel relay

The clearance, or gap, of the valves on a 2002 Mitsubishi Lancer OZ Rally is the distance between the valve and the valve seat when the valve is in the closed position. The clearance is typically specified by the manufacturer and is measured in thousandths of an inch.
To determine the valve clearance for your Lancer OZ Rally, you will need to refer to the manufacturer's specifications or service manual for your specific model. The valve clearance may vary depending on the type of engine and the specific application of the vehicle.
It is important to maintain the correct valve clearance on your Lancer OZ Rally to ensure that the engine operates efficiently and effectively. If the valve clearance is not within the specified range, it may cause problems such as reduced engine performance, increased fuel consumption, and increased emissions.
To adjust the valve clearance, you will need to remove the valve cover and use a feeler gauge to measure the gap between the valve and the valve seat. If the gap is not within the specified range, you will need to use a wrench to adjust the clearance by turning the adjustment screw on the rocker's arm. It is recommended that you have the valve clearance adjusted by a qualified mechanic if you are not familiar with this process.

You may be having a problem with your IACV idle air control valve. It is located on your Throttle body(follow the tube from your air cleaner to the throttle body) It will be on the the right below the tube. It is held on by three screws. It runs $430 at the dealer. I got one off of a junkyard throttle body for $30 and recycled the rest of the throttle body.

what fuel is good for (lancer 2003 es ) is it octan 90 or 95
