Intermittent starting problem with my 1998 Hyundai Accent 1.3i
I have recently started having problems, here is a description and what I have tried.
Starter does not turn, engine does not crank, dash lights are on, no noise, lights work but dim for a second ot two then go bright again.
After pushing car it will start. Sometimes when you stop the car it will start, sometimes not.
Battery is checked and is fully charged.
Weather is cold at the moment below zero at times.
Any help appreciated, I suspect starter motor, if it is how easy is this for this to be changed and how do you go about it.

Re: Intermittent starting problem with my 1998 Hyundai...
First off, when it wont start check the voltage from the battery cable where it connects to the starter, if you have 12.5 volts there that will take battery cable corrosion out of the equation, then check to see if you have ground at the starter, which it sounds like you do not. it sounds like your ignition switch but hard to say from discription, make sure your battery cables are all tight, if you have all of this and its good i would say its the ignition switch which you can look up how to test in a chiltons or haynes manual from the auto parts store, if all of that stuff is good you can take the starter off and have it tested for free at autozone or any autoparts store, but usually the starter goes out really quick or just quits all together, if your not hearing a click noise when you turn it then your solinoid isnt engaging and means you dont have ground to it due to a short or bad ignition switch, that about covers the whole starting system, fuse isnt bad since it works sometimes. good luck hope that this helps you send me a message if you need more indepth help =)

it sounds like a glow plug issue. perhaps a bad glow plug relay. I would think its the relay if the problem comes and goes. If it were a bad glow plug the problem would be constant. check for volts at the glow plugs next time the car acts up. If you find no volts, tap on the glow plug relay next time you turn the key on. This may cause it to activate. if so then replace relay
intermitten problems are the worse, when it wont start check fuel pressure with a gauge, and then check for spark, i have spent days on problems such as this, what you have to find is what is missing, fuel ,spark, is maybe coolant leaking into one or more cyls, i have seen air in the fuel system that only cause problems when under hood temp is high, open the hood and it cools enough to to start, hope this helps
As for the issue of the idle revs, that's perfectly normal. When it's cold outside, every car is supposed to have a higher rev in order to warm up the engine quickly. In more advanced cars, the computer wont even allow the engine to shift into overdrive when it's cold outside in order to avoid extreme engine stress and damage. When it's warm outside, the engine doesn't need to idle high because the engine is already at a good operating temperature. Not much will be needed to get it to the right temperature.
There is a long list of things that could cause intermittent jerking. I'm going to name all of them for you, but your best best would be to go to a mechanic and have them do an inspection.
Clogged PCV Valve (Possibly if you don't get your oil changes on time, sign of a tune up)
Bad DIstributor Cap (not likely at 140,000 miles)
Clogged fuel filter (Very likely, usually done with tune up)
Bad Fuel Pump (Not so likely)
Defective ECM (also not likely)
Vacuum hoses/leak (not likely but possible)
MAS (Mass Airflow Sensor--not likely but possible)
Fuel INjectors (if so, sign of a needed tune up)
Faulty Spark Plug Wires (not likely if tune up is recent)
Faulty O2 Sensors (possibly)
Clogged Catalytic Converter (Possible)

Check for headlight relay and fuse. Some cars have separate circuits for head light flasher and normal high/low beam. From your description, I would suspect a bad connection to/from relay or relay itself.
