Still have a problem with hot starts
I have had a problem with hot starts with my 2000 Silverado 5.3 engine.
It starts right up when cold or within 5 minutes of running at fully hot.
Aftger 5 minutes or so, it takes turning over up to 10 seconds before starting and then it idles rough for a short time. I took it to the closest Chevy dealer and they checked it over and were perplexed having never had a problem like
that. They check the computer, checked the fuel pump (good pressure), cleaned out the fuel lin and installed a new fuel filter. I put this on the internet and someone said it was the Engine Coolant temperature sensor.
I changed that today but I still have the problem. ANY IDEAS?
