Hello, I have a 2000 Mazda Protege LX with 38k miles on it and a 1.6L engine and it starts fine in the morning to go to work and starts fine in the afternoon to go home from work. If I get home and change clothes, hop in the car to go somewhere, it won’t start, turns over like it’s out of gas, sometimes sputters and lopes before it just stops firing. It seems to only do this in the afternoon, specifically between 3pm and 5pm, never after dark or in the morning. I can drive all day long as long as I don’t cut off the engine. After sitting for about fifteen to thirty minutes, it will start like nothing ever happened. So far, it only does it once per day. After I get it started in the afternoon, I can seem to go anywhere, stop as many times as needed, and it keeps starting every time. It seems to be getting more frequent as the weather warms, never did it in January or February, but so far has done it every time I try to start it when the temp is around 80 or higher. I get no engine light, temp gauge is normal. Any ideas? Thanks.
Have a mechanic check the fuel pressure at the injector rail. You might need a fuel pump in the near future.
If you were not getting spark, it would set a check engine code for a misfire.
