A friend of mine owns a 2000 Tiburon, its a 4cly manual, (im unfamilliar with Hyundai model designations). So heres the scoop, his car seems to randomly die for no apparent reason and none of the shops (including a Hyundai dealership) has a clue as to the problem. Apparently it happens more often when its moist outside, the car will be fine one minut then die. The kicker is that itll just start working again at random. He said that it sat for a month without starting then just stared up one day and was fine for a week then died again. At first they replaced the fuel pump and said it was ok, but that didnt fix it. The most recent mechanic thinks its a camshaft or crankshaft sensor, altho im a bit skeptical because there is no check engine light (which in my experiance, in most cars it comes on when you have a bad sensor). If anyone here has any suggestions they would be most appreciated. Thank you.

 

Equinox_01, welcome to the forum.

I have had a Dodge Neon that would do react closely to the symptoms you desribed here. It was the Crankshaft position sensor. Found out the hard way after having the car towed the last time.

No check engine lite ever !! (a code scanner did find it threw up a few CPS errors tho')

I would explore the sensor option, it usually can be bought locally and there are likely folks here that can guide you on the install.

When I had a different issue with my car, my mechanic mentioned that when a car randomly stalls and/or won't start, the Crankshaft Position Sensor is the most likely culprit. I say have your mechanic replace it if he thinks that's the problem.

 

Well my buddy called me last night, according to the current mechanic the fuel pump is shot. Altho the pump was just replaced not too long ago, is it possible that something else is causing the pump to go bad? It just seems so unlikely that a second pump would go within such a short amount of time. Any advice?

 

I doubt it's the pump. If one of the sensors is bad, the pump will be turned off by the ECU. I'm still thinkin' crankshaft position sensor.

 

Hey, I had the same problem with my 98 Tib, other then it did it all the time, as soon as the car warmed up, not when it was moist outside. It was the crankshaft position sensor, I tried replacing the camshaft sensor first, but it ended up being the crankshaft one. Hope he figures it out, and by the way, it's easy to do it yourself, no sense paying someone else to do it, it only takes a minute.
Later,

crank sensor.
