94 Toyota Celica hard to start sometimes I have keep pressing the gas and then car starts dies unless is continuously pressed?

Here are some potential causes and solutions for the starting issues you are experiencing with your 1994 Toyota Celica:

1. Faulty Fuel Pump: A weak or failing fuel pump can cause difficulty in starting the engine. Have the fuel pressure checked to ensure the fuel pump is delivering adequate pressure to the engine. If the fuel pump is faulty, replace it with a new one.

2. Clogged Fuel Filter: A clogged fuel filter can restrict the flow of fuel to the engine, causing starting problems. Replace the fuel filter if it is dirty or clogged.

3. Faulty Starter: If the starter motor is faulty or the starter solenoid is not engaging properly, it may cause difficulty in starting the engine. Check the starter motor and solenoid for any damage or malfunction and replace them if necessary.

4. Failing Ignition System: A weak spark or faulty ignition components can affect the starting of the engine. Check the spark plugs, spark plug wires, distributor cap, and rotor (if applicable) for signs of wear or damage. Replace any faulty components.

5. Idle Air Control Valve: A malfunctioning Idle Air Control Valve (IACV) can affect the idling speed of the engine. Clean the IACV or replace it if it is faulty.

6. Battery Issues: Ensure that the battery is holding sufficient charge and that the battery terminals are clean and free of corrosion. A weak battery or loose connections can cause starting problems.

7. Fuel System Leak: Check for any leaks in the fuel system, including fuel lines, fuel injector seals, and the fuel pressure regulator. Fuel leaks can cause air to enter the system and lead to starting problems.

8. Check Engine Codes: Connect a diagnostic tool or have the vehicle scanned for any diagnostic trouble codes (DTCs) stored in the ECU. These codes can point towards the root cause of the starting issue.

9. Throttle Position Sensor: A faulty throttle position sensor (TPS) can affect the fuel injection and ignition timing, causing starting problems. Check the TPS and replace it if it is faulty.

If the starting issue persists or you are unable to identify and fix the problem yourself, it is recommended to take your vehicle to a qualified mechanic or automotive repair shop for proper diagnosis and repair.
