Need a little more info

To help diagnose the problem need the following: 1. Did you replace the parts listed before or after you experienced a no start problem? 2. If you replaced them before how long did you drive the car before it would not start. 3. Have you pull and inspected the rotor recently to make sure it did not come loose or the drive plate has not severed? 4. How have you determined it is getting proper fuel? Let me know and I will try to advise. Kent

will not start

1 the original problem was that it was not idling when in gear at stop lights. It seemed to load up with gas and stall. When I checked the plugs cap and roter that were only 10 months old the plugs were fouled the cap and rotor looked like they were 10 years old and corroded.After I changed the parts it would not start at all. 3 I looked at the rotor and it looked ok but I will recheck. The fuel pump and filter are only 8 months old and are pumping fuel but I will check the pressure. Is there a chance that the coil or plug wires are not putting enough spark to the plugs?

I have the same problem. I changed the fuel pump relay and sometimes it runs great. Sometimes the car shut off by itself when I am in gear or when I put in gear. After a few tries of cranking the ignition, if it does not start, I unplug the fuel pump relay and put it back. Then it will start. I thought it was the relay, but I changed a new one, same problem.
