verify that the crank position sensor is properly installed, it also may need to be taken to the dealership to have a crank sensor relearn. also check hte ignition timing.

check the distributor cap and rotor for cracks and buildup of carbon. also check the spark plugs and wires.

check hte air cleaner box, it may have a hole in it causing the PCV and MAF to malfunction causing hte engine to run roughly maybe even not start.

the temp sensors would cause a problem, but it still should start, try a new one, they are cheap and easy to replace.

when you put in the new pcm did you get it programed?
