'93 Grand Am 3.3; Intermittent no start when warmed up

[tdinning]

Car always starts just fine when cold. Once fully warmed up, say 1/2 hour of driving, the starter & solenoid will sometimes not engage, until car sits awhile and cools down. Then it operates normally again. I have adjusted the neutral safety switch, and replaced the starter solenoid. Could the N.S.S. be affected by heat, or should I look somewhere else?

check the grounds on the engine block and at the battery. The heat will affect the starter, but you almost have to have a big exhaust leak blowing on right on the starter.
