2000 pontiac sunfire wont start when warm by mi325i

Just did a head gasket, waterpump, plugs and wires. I flushed the cooling system which took quite a bit of time(45 min.). The vehicle was running the entire time and seemed normal. The next day I started it up and it ran fine until it reached normal opperating temp, then stalled out and would refire. After several hours I rechecked and it started fine, and again stalled when it got warm. It will run if you work the throttle, but missfires, sputters, and lacks power. No smoke of any other signs of a faulty head gasket. P.S. I,m no rookie when it comes to cars, this is about the 10th head gasket I've done. The installation procedures were by the book, and the head was resurfaced. Please help.

if you think it might be something electrical then it sounds like a faulty ground somewhere. perhaps the main ground. if you think it's something else perhaps the fuel pump is shot. if it were the starter i don't think that it would work intermitently it would probably just get progressively worse also if it were the starter you would probably crank crank crank nothing then crank crank crank voom car starts. have you ran out of gas recently if so turn the ignition on up to 20 times without starting the car each time pressure will build up in the fuel line. and you wont have the problem again.

found out that my 2003 sunfire has a new problem. When trying to start it, it doesn't do nothing no sound or anything it's like the ignition switch is dead or something. Could it be a neutral safety switch or something like that. please help.

Hey, I've changed a resister once before its on the passenger side just above your feet above the heater blower motor it's not to hard to change only 3 screws if I remember corectly.it only takes about 15 min or so I think I also removed the blower motor at the same time and cleaned out the leaves and dirt that gets in there.You should see it sitting above the blower motor on the top left corner.
