Engine sputter while driving; diagnosed as number 6 cylinder. Tune up done including spark plugs, wire, and air filter. Ran great for a few days; no check engine light. Sat for a couple of days, went to start it and it turned over great but wouldn't start. No check engine light on. Changed fuel pump, still won't start. Checked all fuses. Please help. I've spent over five hundred dollars on a vehicle i'm still paying for!
I am lloking for why my 1997 Kia Sportage wont start which is a 4cyl. Tune-up done all filteres look great. Getting gas and all belts are turning. Someone told me it could be the crankshaft position senser? Please help.. This vehicle has sat for about 8 yrs and am just now working on it. It has been garage kept.
\I WAS HAVING THE SAME PROBLEM, IF THE CHECK ENGINE LIGHT DOES NOT COME ON, IT COULD BE A CLOGGED CATALETIC CONVERTER, THE EASIEST WAY TO TEST THIS ,TO ME ANYWAY, IS TO DISCONNECT THE EXHAUST PIPES(COMING OFF THE ENGINE) AND THE CONNECTION TO THE FRONT OF THE CATALETIC CONVERTER, THEN START THE CAR AND SEE WHAT IT DOES, IF THE ENGINE SURGE GOES AWAY(REMEMBER THE CAR WILL BE LOUD) BUT YOU ARE LOOKING FOR THE ENGINE HEALTH TO GO TO NORMAL, IF IT DOES YOUR CAT IS CLOGGED

If this is a sudden occurrence and nothing suspicious happened prior, you most likely lost either gas or spark to the engine. You need to check for both.
Do you hear the fuel pump in the gas tank buzz on for a couple of seconds when you turn the ignition key to ON? Unless the fuel pump turns on and puts gas under high pressure at the fuel injectors, the engine cylinders won't get gas to start. Correct fuel pressure is crucial to know if you have a fuel pump (or fuel filter) problem. If the pressure is correct, it is probably not a fuel problem but a spark problem, although there are less common instances where a fuel injector circuit may malfunction.
The ignition system not producing spark at the spark plugs is the other common problem of no starts. Buy a cheap spark tester at a parts store, plug it into one of your spark plug wires, then crank the engine over and watch for a strong blue spark. You might need a helper to do this. If you see a consistent spark, the ignition system is probably good, although you should probably check more than just one plug wire-sometimes one bad ignition coil in a coil pack will cause no starting. Good luck.
With the engine off first loosen all the spark plug wires and just lightly place them on the spark plugs.Now you will need some plastic plyers or something to remove the wires without getting shocked.
Start the engine and one at a time remove and replace each wire and see if it makes a difference in how the engine runs. If it does not make a difference then thats the problem cylinder. When you find the bad one check and see, maybe the coil for that cylinder is not sending a spark. Or if it is sending a spark, maybe that spark plug is no good.
I hope this helps you.
Does it cranks when you start the car? If so, it could be your distributor unit is bad. Check you spark plugs and wires. Test if there is spark produce by your spark plug wire when u start the car (unplug the wire and put it close to the engine valve cover and start the car).
A tune up is generic. i don'y have specific part numbers or anything, but a tune-up generally consists of:
Spark Plug replacement (6 of them)
Spark Plug Wire replacement (6 of them)
Fuel filter replacement
Air filter replacement
On older vehicle, one would check all the components that involve spark, such as distributor cap & rotor. You might not have these, yours may be computerized, no service required until it fails.
A tune up would also include a review of all recommended service items as noted in your owners manual. Some of these might be mileage related. Such as, timing belt & transmission fluid replacement.
I normally do not do tune-up's unless the vehicle is having a problem. If you end up taking your vehicle to a mechanic to diagnose a problem, he will suggest many of these items before beginning his diagnosis.
Do not attempt any maintenance on spark plug if engine is hot. 1. Disconnect negative battery terminal. 2. Carefully remove high-tension leads. 3. Use compressed air to blow any dirt or debris from around spark plug hole. 4. Check that spark plug fits squarely in spark plug socket and remove spark plug.
Raise a vehicle and install SST(OK552 131 001) in order to replace cylinder 2, 4, 6 spark plug.
