Why wont my car start?

Starter may be toast , if the interior lights blink it could have something to do with anti theft and you may have to unlock the car or use the right key

It depends upon what actually happens when you turn the key. If the engine turns over, but doesn't start, it is NOT the starter. If all you hear is a clicking sound, or the starter motor engages but doesn't have the power to turn it over, then it could be wither the starter or the battery. A quick and easy check when this happens is to turn on the interior light. If, when you turn the key and get the click or no activity, the interior light dims way down or goes completely out, it is probably the battery. If you turn the key and get nothing at all, things are more difficult. The interior lamp test should be performed. If the light goes out immediately, try the battery. If the light doesn't flicker or dim at all, then the problem could be the starter, the starter relay, the Park/Neutral Position (PNO) switch, the ignition switch, or the IGN E (Fuse 22) or IGN A (Fuse 34) fuse in the fuse block under the hood.

check fusible link also check for power at starter first..make sure trigger wire is good at starter

A mechanic would check for voltage at the starter, the neutral safety switch (automatic) and the key switch.

CHeck for loose/bad connection at battery and starter.

Voltage drop testing the starter circuit . Bad connection , battery cables etc.....
Starter Voltage Drop

sounds like a bad connection,it wont heat up the solenoid or the starter,check your hot and negative cables from battery to starter first could be the starter itself, ggod luck

I would have battery checked/charged and/or replaced. Then starter, then alternator checked.

starter/solenoid issue.

Do the dash lights come on ? They should come on when the key is turned to the on position. If nothing happens check the engine relay. It is not too expensive to replace if you really want to eliminate that as the problem. Check all wires going to the starter and make sure it is wired correctly.
