My son has a 1999 Hyundai accent 1.5liter 5 spd, the car starts ok then dies and sometimes is hard to start back up. It looks like the plugs fowl right up, new plugs helped but not long. It has new plug wires and coils. Sometimes when he goes to fuel up you cant put gas in it, it just spits the gas back out of fuel filler like its vaccume locked.... HELP

Don't understand what you mean by the clutch started to get hard to put in gear, please explain what that means.

This is starting to sound very much like a blocked catalytic converter on the exhaust system. Try unbolting the exhaust in front of the catalytic unit and see if it will start and run normally. If it does then the unit needs replacing, if not then thats me tapped out for ideas.

This sounds to me like an intermittent crankshaft sensor problem. Did your CHECK ENGINE light come on? Crankshaft sensors sometimes flicker this way before they completely die, sometimes they don't. I think you may have a flickerer. Have the code checked at your local Advanced Auto or Auto Zone. The part is only about $30.00. GOOD LUCK.

If not starting U have either a fuel delivery issue or a no spark situation. Open a fuel delivery joint by the engine and turn on the ignition. If fuel squirts out the pump is fine and the hassle is with the spark. Could be bad igniter causing either no spark or a weak one.

When it dies..check for spark. You could have a component in the ignition system failing when the car gets warm.

If you don't have spark then you might need a new ignition module. The distributor cap and rotor should be checked for traces of carbon. This would be evidence of a leaking cap.

If you get check engine codes then you do have some sensors going out of range or failing all together. P0446 is an evap code right?
Make sure your fuel cap isnt plugged up and all your evap lines are ok.

Changing the pump doesn't affect the spark so lets start a that the beginning?? Why was the pump replaced and was it running fine before changing the pump? Also plugs could be fouled as well but if it was working fine before the fuel pump it will be fine afterwards if getting gas and the fuel pump was the problem., Also how did you verify no spark??

Fuel filter partailly plugged, or bad spark plug wires.

I had a similar problem and had an engine tune up done and the car runs almost like new now. Mine is a 2001 Hyundai Accent too.

ok when the check engine light comes on that usually indicates a engine malfunction...what you can do is go to your local autozone and they can do an OBDII test for free..my bet says it is the cam or crank sensor.. DO NOT SHUT THE CAR OFF AT AUTOZONE..LOL

HI
when it was battery fault no restarting again because of died power in the battery ????
so the alternator or harnesses is the most causes

ASK ME FOR MORE INFORMATION
