Question
i replaced coil,cap,wires,roter,plugsm and after 30 min shuts off but will start back up after 10 min

Answer
What is it that you do NOT have when it won't start. No fuel or no spark to the spark plugs ?.

Try this when it won't start:

Fuel pump test:

1. Get yourself a helper.

2. remove the gas cap.

3. have one person listen in the gas tank at the gas cap opening.

4. have the other person turn the ignition switch to the ON position ONLY so as the dash lights come on. Do NOT attempt to start the engine.

5. As soon as the ignition key is turned to the ON position, The person at the gas tank should hear the fuel pump run for TWO SECONDS and then it should STOP.

6. Does it ?.


If you do NOT hear it run, in most cases the fault is the fuel pump relay or the fuel pump..
