Hi
I have a 1998 Hyundai Coupe FX (Tiburon) with a warm start problem, when the car has reached operating temperature, if it is switched off, it will not restart until it has cooled down.
It's the 1.6 engine version.
This problem began happening a few weeks ago, but is really only noticable on multiple short journeys. On the road, it seems to run fine, although the idle is a little rough & it stumbles at idle sometimes.
Today, I let it warm up & noticed during the warm up phase, at one point it appeared to stumble, almost cut out, then recovered, then carried on as normal. When I switched it off, then on, it would not fire up.
Cranking is fine, but there are no sparks at the plugs.
The coil seems OK, resistance wise, the plugs were changed recently.I suspect some defective sensor is preventing the ECU from driving the coil.
I had a look at the Hyundai tech pages, nothing exactly like this problem, although they do say the crank sensor might be a reason for a no start condition. The camshaft sensor is also a potential failure point.
A Google search turned up lots of starting problems, but nothing related to temperature.
The car starts first time from cold, every time.
Has anybody seen anything like this before?
Which sensor is not critical, as one seems to cut out when hot, but the engine runs anyway?
Where exactly is the ECM (ECU)located?
Thanks
Gerryo
