2004 chrysler sebring. no engine codes and car still won't start

No auto shutoff that I'm aware of. Check cam and crank sensor if you're not getting good spark

code p 0128 refers to coolant thermostat--coolant temp below thermostat regulating temperature ===causes --mechanical fault
replace the thermostat
your problem may be low fuel pressure from a faulty pressure regulator
have the fault codes read professionally as the code you have is not related to your problem

You will need to have the electronic engine control module scanned for fault codes, there will be a code even if thelight is not on.

Code P0700 just means the trans computer has a code. You need to have the trans computer read to get the trans code p0034 the rubber turbo hose to the inlet manifold which had a small split in it causing it to loose pressure these codes will not make your car not start check battery to see if its dead again does the engine turn over at all when you put battery back in car is terminals tight

I would try replacing the fuel filter and also take a look at your air filter and vacuum lines.
hopefully this solves your problem

Some of the Sebrings have two filters(one is called a sock).The sock(which all sebrings have) is located in the fuel tank itself on the pump module.If this model is the JXI then the external filter is located on the belly of the car between the tank and drivers rear seat. I hope I could help!!!

Make SURE you have enough oil in engine, check dip stick. Make sure oil is not leaking from drain plug or oil filter.

The fuel filter should be changed first.
The engine fuel pressure over night is bleeding down into the fuel tank. I would suggest a tune up . If the condition continues after a tune up. The fuel pump is starting to go. You should then have a mechanic check out the fuel system and have the vehicle diagnose.

I would check if it is in the gas tank on that model. you can go to your local parts store and they should be able to inform you of this.
