Why is there no response when stepping on the clutch to start the car?

[DiMiles]

The reasons for no response when stepping on the clutch to start the car are as follows: 1. Insufficient fuel pressure. 2. Incorrect signal from the throttle position sensor. 3. Poor performance of the fuel pump. 4. Poor performance of the spark plugs. 5. Poor performance of the distributor. Solutions: 1. If the horn and headlights respond: Use a screwdriver to test for spark at the negative terminal of the car's ignition wire. If no spark is observed, there may be a short circuit between the ignition coil's low-voltage terminal and the ammeter. If the connection between the terminal and the wire is poor, clean the terminal first and then tighten the nut. If a section of the wire is found to be short-circuited, replace that section of the wire. 2. If neither the horn nor the headlights respond: Use a wire to test for spark at the starter's terminal. If there is spark, the fault lies in a short circuit between the starter and the ammeter. If no spark is observed, the issue may be due to insufficient battery charge or a wiring fault. 3. Use a screwdriver to test for spark at the ignition coil's negative terminal: Test for spark between the distributor's contact arm and the base plate. If there is spark, the fault is with the contacts, which can be fixed by adjusting the contact gap with a platinum sand strip. 4. Test for spark at the distributor's insulated terminal and the distributor housing: If no spark is observed, there is an open circuit in the wire between the distributor's insulated terminal and the ignition coil's negative terminal. If there is spark, the fault is an open circuit in the wire between the insulated bracket and the insulated terminal. If the connection between the terminal and the wire is poor, clean and tighten the terminal and wire head. If a section of the wire is found to be open, replace that section with a wire of the same specification.
