Hi, Car will start fine and runs perfect, however after a long run (1/2 hour or more) wont start straight away wait 10 mins and away it goes, turns over fine just doesn't fire

SOURCE: 98 Elantra that just stops running

check to make sure the catalytic converter is not clogged,easy way to test is remove the oxygen sensor before the converter and see if the engine still runs if so cat is probably clogged,get back to me if you need more help,please rate my fix as i strive to be the best Thanks Ray

SOURCE: Car wont start after I fill the tank

I have seen this many times on Sonatas. The problem is likely to be your cars Purge Control Valve sticking open and allowing fuel vapor to be pushed into the engine while filling the car with gas. This valve is mounted near the intake manifold and has a vacuum line to the manifold and another that routes under the car to the vapor canister.

SOURCE: Car not starting - Intermittent

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

Testimonial: "Thanks for replying. My initial thought is that the problem is temp related, so I will try your suggestion of leaving the bonnet open."

SOURCE: Car dies like it runs out of gas but has half tank

The EGR valve will not opon when the engine warms up so that is why it dies out

SOURCE: the car starts fine and

you did'nt specify what year,engine size, or model. but what you describe,is a common poblem.the engine idle control sensor may be bad.is your check engine light "on"? this may be why the lights on. but the light may not be on at all, and the idle control sensor may still be bad. it starts fine, then idles fine for awhile,until you put it into gear to drive it,then it sputters,or dies. or else you start it and then put it into drive on the clear road,then give it full throttle gas on the floor,it takes off fine and runs great,until you come to stop sign or red light,then it dies? suspect a bad idle control sensor 1st then suspect clogged fuel injectors. which can be cleaned easily by adding sea foam,or lucas fuel injector cleaner to your fuel tank. no service fees due. thank you for choosing fixya.com. we always look forward to assisting you in your needs,automotive,or just about anything you need assistance with,fixya.com can assist you with! and again,thank you for choosing fixya.com!
