Bought car 2 months ago. After 2 weeks, wouldnt start after driving awile. Started after 5 or so minutes. Week later, same thing, except 2 hours of sitting. Replaced starter/solenoid and new positive battery cable to starter. Great for a week, then same thing. Full battery power, turn key, hear fuel pump, nothing. No click or nothing from starter. All accesories work, full power to everything.

Followup. Changed out the ignition switch box. Nothing. Knew positive cable good, so the small wire into solenoid(figuring it the signal to start wire), jumped it and car started. Drove it home to my garage. Turned off. Restarted 4 staight times. All inside and outside ignition fuses good. Can feel clicking in fuse box when turn key. So whats left after fusebox to signal starter? And since its doing this off and on, assuming a short?

So you changed the ignition switch?To me it sounds like something gets hot while it runs then fails when you go to start it till it cools down. Iam thinking maybe the neutral safety switch since that gets hot.

Alright to test the neutral safety switch when it wont start and the transmission in park. In the start position the red wire with a light blue stripe at the neutral safety switch will have power. Then the white wire with a pink stripe wont have power at the neutral safety switch.
