It is also hesitating starting .have to hold the key a lot longer for it to start.don't have the machine to check it any other way to check the exhaust?

I use a thermometer . But you could use a stethoscope and listen for air flow. Any check engine light? Need more info dude. U could have a number of issues. Ie. Faulty crank sensor. Bad pcm. Electrical. Lots of stuff. Like how's your coolant? Is it low?
