Why won't it start?

Can be dirty or poorly connected battery terminals...lights etc can still work...but the starter requires good clean connections to crank (Draws more power) Also, the battery can have a bad cell causing the same symptom...have battery tested too...if not, the starter is bad. Hope this helps.

My Reduced Power light comes on for no apparent reason and service traction stabilizer light also, truck chugs and rpms go up but no power to go over 20mph

Your reduce power light is on for an apparent reason, it is running rough! Scan for a code and it may end up being a bad throttle position sensor and dirty throttle body.

Battery warning light is coming on for no apparent reason. I just replaced the oil pressure sending unit and then reconnected the neg cable and now warning light stays on.

Try removing either battery cable for about 15 mins. that should reset the computer in car and make battery light go off, if that dont work check battery cables to make sure they are tight. Billy Wyatt

Service engine soon light

try disconnecting the battery for ten min. and re connecting it. This will reset all sensors. The light has about 77 reasons for coming on. Could be a small as a gas cap not sealing properly. If it comes back on, you may have an issue somewhere. But try the battery first

Battery light is on

The battery light comes onwhen there is not enough "back current" coming from the battery. Check the battery's voltage and amperage at a parts store and they can tell is it is bad.
If the battery is good then I would, at the same time.
check the cables and posts for clean contacts(the most common reason for low battery performance is
dirty connections. Let m know if ai can be of further help.

The ABS,Brake Light,Battery light go on and off sporadically while driving.Does this indicate an Alternator failure or a sensor/computer problem?

yes it's most likely a alternator problem,usually the internal diode bridge breaks causing all lights you mentioned to come on,if this happens at a idle open the hood and remove green connector on alt.if lights go out you've found the problem
