You will have to remove the grill and the park lamp first and then you will see some 10mm bolts to remove the headlight. It has been a while since I have worked on one but the grill will have screws on top and clip at the bottom I think. I hope this helps.
Water pump is a bit tired and not flowing as much to handle the higher work load. Give the radiator a good flush first and see what comes out. Might come good if you flush the donk as well.
could be the battery is old and losing power, ie not enough to turn the starter motor fast enough to start. Or the starter motor itself is worn and will not turn fast enough,
ensure the connections to the battery and starter are good. if the battery is older than 5 years i would be a good idea to replace with an new one of the same power rating and size.
in winter it is often the case that old cold batteries do not perform well. if with a new battery the problem persists, remove the starter motor and have it checked, if it is defective it would have have to be removed to install a replacement.
one way to check battery power is to try and start the motor with the headlights on if the lights dim down a lot when trying to start that indicates the battery is low on power.
i hope this was useful.

yes auto or manual vehicles must have the flex plate (Auto), flywheel (Man) installed in correct position while engine is at top dead centre cylinder 1 firing. flywheel has notch in it which goes at 6 o Clock when looking at back of engine & flex plate has notch go at 12 o clock.
Did they check the fuel flow ?, a blocked fuel filter can give a good fuel pressure reading but little or no flow , and cause the problem you are having.
In almost every case the transmission must be torn down and rebuilt to cure this problem. Have a local shop properly diagnose the issue as the rebuild job runs about $2500.00-$3000.00 USD
link explains what it telling you and how it works.https://www.youtube.com/watch?v=mq3jR-IMNHQAll four wheels are in drive when all four tires are green. Could also be in f wheel drive low. 4x4 low is talked about also at the end of the video. You do not want to be driving at high speeds in 4x4 low, at lease with the 4x4 I have owned.
