starting issues

Anyone ever have issues with their GT starting. My 99 GT doesn't start when its too hot or if I've drivin for more than 30 min. Its just cranks over and over and won't start. The goofy thing is if you let it sit AFTER trying to start it for 30 min, it'll fire right up. Advice? PATS system?

It sounds like a crank case sensor to me

Mine is the opposite if it's below freezing it don't want to start but if it's warmer it starts the first try

Mines tricky. Sometimes it starts right up. Other times it takes two cranks to kick it over

Id imagine if it were a crank sensor id get a check engine light and i dont get anything. I was also thinking maybe its my coolant temp sensor reading the car is too hot to start. And the ignition switch tested ok.

Your starter windings may be worn .when they get warm they don't work as good.also check your grounds.

Have your battery tested. It's probably bad

Battery shouldn't have an affect with temperature change like that. Check your starter plus crank case sensor. If the sensor is bad it won't always throw a code.

I guess I should ask the question if it cranks or not

I guess that's true...battery tests ok. The car sits with the battery disconnected. Sometimes when it just cranks for 5-6 sec its almost like a switch turns on and it'll start. Its the strangest thing. The crank sensor makes the most sense but i don't wanna tear *** into my motor if it isn't.

I would go with this suggestion!..people sometimes run into this problem after installing headers when they sit close to a starter the starter lags enough to make it hard to start!...simply letting it cool of usually fixes it temporarily..

I do have headers...header wrap solve the issue. But i have driving it to work it sits for 8 hours and it won't start right up. I have to try it, let it sit, and retry after 30 min and it'll fire up.

They also make a starter blanket/wrap.it is easier than wrapping the headers.summit racing sells them for 20$.I would still suggest a new starter though.also look into the smaller diameter ones.they will give u more header clearance.

Yeah my car had a new starter on it and one night the water pump went out and it got hot. Use to crank fast amd start right up. But when it got hot it wouldn't start just crank real slow. So I let it set for a while. Then drive it home just mins away. But now I put the new water pump on it amd it still crank real slow but starts up. So I think the windings in the starter r bad now. I also have headers. With no heat wrap on the starter. Does it crank regualar or does it crank slow. If it cranks slow replace the starter
