94 Lightning starting problems
The other day at work my truck acted like it had a dead battery when I went to crank it.( turned over really slow) Today it kept cranking over for about 10 secs then sputtered and then ran fine.
Im going to put my new battery from my 86 in it later today and see if that changes anything. Thinking It needs a full tune up. (plugs,wires,dist cap and rotor.)
Also the other day I noticed the o2 sensors were disconnected. Have anything to do with this?

Plus I used the wiring harness and its all color match connections. (cant really screw that up)
Today when coming home from work it started just fine but I heard a clicking in it for a little while. It went away and I got home and didn't hear it anymore...
I thought it was an exhaust leak right when I heard it.

Still cranking slow? Some possible causes are, battery low on charge, battery terminals loose/dirty, grounds loose dirty, wiring connections to starter loose, bad battery/starter wires, bad starter, ignition timing incorrectly set.
A low battery can be caused by bad battery, bad alternator or current drain with key off.
Why are your oxygen sensors disconnected? Shouldn`t hurt starting but I would have thought it would hurt gas milage.
I would go ahead with the tune-up and add a fuel filter to your list. Hope this helps.

No idea why the o2 sensors are unplugged. It was like that when I bought it. I know it did have a MAF kit and supercharger on it before I bought it though and was brought back to stock when it was put up for sale.
Ill order the tune up stuff ASAP. Also going to put my other battery in it when I have the time.
I need to check the timing also. I would like to bump it up to 14* for alittle extra power.
