Question about 2003 Dodge Stratus
This all began after replacing head gasket and timing belt
Symptoms of a P0118 could include: A code P0118 may mean that one or more of the following has happened:
Low temperature results in a high signal voltage. When the PCM sees a signal voltage higher than 5 volts, it sets this P0113 check engine light code.
P0118 - The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor. The PCM monitors voltage drop to determine coolant temperature. If the ECT reads less than freezing temp. when engine has been running for more than a few minutes, the PCM determines a circuit fault and sets this code. Or if the PCM determines the sensor resistance is out of specs, this code is set.

First off, you need to label all of the electrical and vacuum lines connecting to the intake manifold. This will make reassembly much easier. Then, there is a torque sequence to be used during disassembly and reassembly.
This image is of the TIGHTENING SEQUENCE. Reverse this to take the manifold off. This is important so that the upper intake manifold is not warped at all, which would decrease the quality of the seal. Be careful during disassembly and reassembly to avoid bending any lines or tubes. If things are in your way, disconnect them rather than pushing them to the side. This will avoid pinching inner linings which cannot be seen visually.
As for the gaskets, (as far as I am aware), Chrysler's (Dodge's) official stance on the manifold gaskets is that they are reusable. However, this is if they ALL look good under close inspection. Any tears, "melting", or other damage means the gaskets should all be replaced. They are not expensive, and I believe they all come as a set including both upper and lower gasket sets. Personally, I would recommend replacing them regardless. This would be a good preventative step to help extend the life of the vehicle. Also be sure to check the cooling line O-rings and replace them as necessary, following the criteria above.
Good luck and I hope this helps, even though I see it is a bit late.

It is possible that this is a zero clearence engine. Meaning that the valves can hit the pistons if the cam timing is off or the timing belt breaks. I would strongly suspect that you have bent valves. This can easily be diagnosed with a compression test. If valves are bent the repair will require at least a rebuilt cylinder head and gaskets. It is also possible that there could be piston damage as well. The reason it is not starting is it has no compression due to bent valves.

SOURCE: 1998 dodge ram pickup 318 eng.
If the engine seems to run fine over 1450 RPM maybe there is a vacuum hose leaking or EGR valve is slightly stuck open. Any help from the OBD II trouble codes? Or is there simply no MIL and no stored information in the OBD II computer read at the local parts store through the connector by the drivers knee?

I had the same symptom and it turns out the previous owner had installed an aftermarket alternator pulley. That pulley, while saving a few horsepower, spun the alternator slower, and didn't produce enough juice to charge the battery at all - at idle I would kill my battery within the hour. I had to go back to a factory pulley, and presto - problem fixed! My lights don't dim to 50% brightness at a stop sign anymore :)
