What could cause an occasional starting problem the car will start when i hit the hall sender switch on the top of the distributer cap?

It would be reasonable and logical that the starter motor or starter solenoid could be the source. Although it doesn't rule out an ignition switch.
Two things in my experience.
If rapid clicks, starter gear probably not fully engaging with flywheel due to insufficient current.
Low battery (may be charging issue if battery is good, Any independent shop will check battery/charging) OR the solenoid is shot (copper connection pads get worn out).
If it is intermittent solenoid, single click but no turn over then try again and works, solenoid is bad as above. Usually this deteriorates over time especially in cold climates like New England.
If you believe solenoid, pull starter out and take to auto electrical shop for a rebuild. If cold climate, the starters take a beating and they will rebuild starter & solenoid.
Folowing not likely but...late models use a relay. The ignition switch controls the relay, the relay feeds the solenoid, solenoid feeds starter. I did have a 1997 Tahoe that was intermittent (turn key twice it starts). I did not believe solenoid was bad since I'm warm climate. This can be (carefully, know what your doing & verify relay part numbers) checked by substituting a relay from another "non-vital" circuit (say air conditioning). The relays MUST be the same so verify part number.
My Thaoe's electrical diagram did NOT show the relay and I almost rebuilt starter. I could not believe solenoid was issue. It was bad relay, $23 at NAPA.
I would be suspicious of a weak battery first because it is only during cold weather. This is when the battery is most susceptible to failure. Drop it off at your local independent shop that you use outside the night before when it is cold, and with a little luck it will happen so it can be diagnosed.
This is caused by not enough power reaching the starter solenoid to make it engage the starter motor. The culprit could be: a) a weak battery (only if it turns the starter slower than normal when it does turn it)b) worn ignition switch contacts c) loose wire connection (somewhere from switch to solenoid) d) a wire that has developed high resistance or become frayed or worn out. e) worn starter solenoid f) on newer models an ignition relay
I had this problem on two older model cars I owned, on both my cars the cause was the ignition to starter solenoid wire had developed high resistance. This is the reason newer models include a relay. I adapated a relay on both my cars long before this addition was included on newer models. This I�ve found is the main cause for clicking starter solenoids, and is very common on earlier models but many times missdiagnosed as starter, solenoid or ignition switch related.
It could also be a bad battery connection. Check the battery cables for tightness and sometimes corrosion.

Where is the oil pressure sender in a 1980 Chevrolet Corvette?
at the top rear of the engine, behind distributer
Why is there no spark getting to plugs on 84 Toyota w 22r motor?
I'm having the same problem. It's probably the pick-up sender in the distributer or the ignition module. Hope this helps you!
Where is the oil sender on a 95 dodge ram 1500 V8 5.2L?
My name is Jason I am a Chrysler master tech and ase master tech. The oil sender is on the top rear of the engine on the right side of the distributer.
Why my Probe gt 95 oil gauge is not working?
Sender unit defective sender unit disconnected wiring problem dash to sender rear dash connector problem defective guage
Why does my 1995 Dodge Neon show an oil pressure light when the oil level is ok and it runs ok?
I would first inspect and clean the connection at the sender. If that did not improve the problem, I would replace the sender. I suspect it is a sender problem.
What could cause Audi a4 intermittent starting problems?
I have an 1998 A6 2.4. I was getting a lot of intermittent starting problems- especially when the engine was warm, i.e. after a cold start. The problem was a faulty Coolant sender. There was also a lot of corrosion in the connector to the coolant sender. It's a little fiddly to get at - you have to remove sthe flexible air intake hose and the housing for the air filter. The new sender was only £12 + vat.
When you turn the key to on the oil pressure gauge goes to high without starting the car?
There is a open on the sender side of the circuit. Ground the sender wire and if it goes to low then it is the sender if not then the circuit is open.
When I receive a web cam from a friend the cam only lasts a few seconds or minutes then goes black is it a problem from me or the sender the sender receives my pic good?
Its a problem. Trash or recyle your web cam. Get a new one. The sender will never receive a good pic if it only last seconds. I would get MMS or texting it works better. Jokes on ME@!!!
What's up your oil gauge go's up and down no matter what rpm's you am at?
Sounds like a wiring or sender unit problem. Ground wire at sender unit, see if it stays steady. If it still jumps around, wiring/gauge problem. If it stays steady, sender unit should be replaced. Good idea to do an oil pressure test as well.
Why doesnt my 1994 mustang temp gauge work?
The problem could be a dirty sensor or the sender is no good.
Why does the oil gauge on your Chevy jump?
Chevrolet had a problem with it's combination sender/switch units used on the 350ci (5.7L) TBI engines in full-size trucks and cars between 1990 and 2000. The sender becomes inoperable due to a loose wire inside the sender itself and makes the gauge erratic. The fix is to replace the sender/switch.
Why would the gauge read empty when the gas tank is half full?
Most Likly a fuel sender problem
