My car will not start my lights, radio work its not the battery. I recently replaced the starter, the altenator, battery, fuel pump catalyic converter. when i turn the key there is no noise it won't even turn over any suggestions. I replaced all 8 coils and spark plugs about a year and 1/2 ago. my engine light is on and i used the code reader and it said P0300 random misfire but will this cause my care to not even start with no noise. Year of vehicle is 2005

Check the key switch.

Check battery connections and voltage. fuel pump only runs for a few seconds to start and runs again while cranking.

I would have that starter tested. It could be intermittently engaging and disengaging. This can happen to the starter drive. I`m not sure why it cuts out after you jump start it,since the alternator takes over after cranking the engine. Unless the starter drive is sticking. My other thoughts are on a fuel pump problem.Or fuel problem period such as an obstruction of gas getting to the engine. Fuel filter maybe or fuel pump relay!

You got a jump and it ran fine? It's your battery. The lights and radio are much easier for a battery to handle than spinning a car engine. Again, if all you needed was a jump, you have a bad battery.

Aftermarket radio set up to play when no key in ignition? Or CB? or aftermarket alarm system?

If so- those can put a phantom load on the battery when it is shut down.

If you do not have those installed, does your fuel pump continue to run? If so- try swapping the fuel pump relay if that does not remedy it, replace the oil presure switch it may be stuck closed.

Radio and lights can work with weak battery, too weak to turn starter.

Noise when shutting off maybe dieseling due to fuel mixture too rich or timing off.

When you say car won't start do you mean starter turns but engine does not start, or do you mean starter does not turn.

could you start it before replacing those items? If not try fuel pump and a tuneup from coils to plugs. If it would try looking at the starter or the wires. If not connected correctly the starter cant funtion.

I'm assuming that by turning over, you mean that the engine fails to turn with the starter . Check your battery for 12v and make sure all connections are clean and secure. If battery has less than 12v charge it and check the charging system after re-starting. Lights and radio do not pull the same amperage as the starter and may not tell you much about battery condition. If you have full battery voltage, check the starter for 12v at the battery connection and the small (trigger wire) for 12v with the key turned to start position. If you have both, likely starter has failed.

most likely its not the fuel injectors, if you here a noise when you attempt to start the car it may be the starter trying to start the engine, if this is the case it is most likely a fuel rail issue or fuel pump the intrepid has always had a poor quality fuel pump which is in tank. if you dont here anything and your horn works and lights and radio then your starter or starter relay or stater solenoid may need to be replaced. if nothing inside works like horn or radio the there may be a ground-strap broken or your battery is dead or the battery cables went bad or broke.
