Father in law jumped car off, shorted fuse in fuse panel under hood, replaced fuse, car would crank but would not stay running and would spit and sputter and shut off.
Took to mechanic, he said computer was bad.
Replaced timing belt, water pump, spark plugs, wires, and spark module. Charged battery and tried to crank, multi-function switch began to smoke on steering column, gauges acted crazy.
During starting procedure, engine made a odd sound while turning over, questioned whether timing marks were lined up correctly. Still need to verify….
Had computer module rebuilt (Auto Computer Exchange, Davie FL), reinstalled PCM, installed new multi-function switch on column (new switch was different as it does not have fog light switch, everything else is the same), installed new battery.
Now have no cluster lights/signals, no overhead lights, motor starter engages but will not turn over (still may be timing belt issue). Headlights turn on, blinkers work, wipers come on, etc.
First of all, you quite possibly could've done some damage to wires/connectors. If the insulation burned and is allowing a wire to touch ground and/or another wire, you'll have these problems.
Also, one/more of the sensors could've been damaged, preventing the vehicle from starting.
What you need to do is check to see if you have spark at the plug. If you do, your computer is recieving signals from ckp/cmp sensors, which it first checks for before telling the coils to fire. If not, you'll have to check that system beginning with whether the coils are getting voltage and a signal to fire. (Test with voltmeter at the coil connector) If no voltage/signal to fire, check wiring/connectors/computer/ckp/cmp sensors. If they are firing, check that timing is on the mark.
If spark is fine, you next check fuel system. Begin with if the injectors are firing. If yes, check pressure. If not, check harness/computer. If injectors are fine/ check fuel pressure/filter/regulator. If no fuel pressure, check relay/wiring/connector/pump.
You could also have the computer hooked to a scanner capable of reading the live data/monitors. It'll show everything electronic that runs the engine. If everything is fine, then it'll be a problem with something the computer can't see, such as low fuel pressure/kink in line/etc.

Any ideas as to why the motor will not turn over with new battery installed? And would these issues you mentioned have anything to do with the gauge cluster/interior lights not working?

If the bat wasn't jumped correctly, you could've done damage to the electrical/computer systems. The only way to tell for sure is to test these systems one component at a time. Unfortunately, this is very labor intensive and it'll take someone who really knows his/her stuff.
