Sounds like the starter relay is going out.
sounds like your in the market for a starter.
My 01 Grand Cherokee had this problem. Sometimes you turn the key and it starts up just fine. Other times you have to turn the key several attempts before anything happens. Sometimes I have to get it jump-started. The extra power from a second battery will overpower the dead spot and it will start right up.
If there is a single click from the starter area, the starter is bad. If not, it could be an ignition switch.
Without knowing even the make of your vehicle, I think you should suspect the starter contacts. They can get burned and worn away and barely make contact . . . or sometimes not.
crank sensor
I had the same problem the car started sometimes and sometimes did not. In my case i needed contacts, the contacts in the starter was bad. It cost me $500.00 so my advice is to buy a new starter the contacts were $12.99 a piece and later on i found out that you can buy a new starter for $500.00
get your starter check I had same problem it was faulty starter
either the kick panel or on the starter itself. sometimes ther are 2 of them
Check your fuel filter, this may be dirty.
Loose connection? Bad starter (flat spot)? Bad starter solenoid?
2004 mercedes truck wont start sometimes. Why
When a starter goes completely out then the engine will not turn over. A starter that is going bad could start sometimes or make considerable noise.
