Revo problems My revo starts to "hiccup" when its hot but fine when cold or cool.

skipped filters?
hiccup.s can be lots of things,
so tell when the hicup ,er misfire happens
hot or cold engine. ? or both.
at any speed. , only fast right foot?, or only wide open throttle?
only on hills. ?
so far , no miss at idle or slow speed.

The problem is with the starter assembly. Replace the starter, and the problem will be over.

I had the similar problem with my 02 santa fe. Someone said it is the crankshaft sensor. How is yours now?

bad cdi

Hi.. I had a very similar problem recoverrd to are workshop by the A.A around a month ago.
Exactly the same problem (left to cool started.? Once worm or hot engine just turning over ?)
Afdter reading all known folts and finding nothing to do with what I'd wanted. It took some time ?
Cutting it sort if found when I replaced a intermittent faulty fuel relay and run till engine hot (untill cooling fan cut in) Then turned off engine .. on turning key to see if this had cured my problem?
The engine started frist turn of key after repeating this a number of times .. this car was now starting fine (whether hot or cold)
Problem fixed..
Hopefully this will be of some help to yourselves

There seems to be an airlock in the system, as for the thermostate you can remove it check it out, fill in some water in a pan,insert the thermostate in it and heat up the water..you will see the thermostate ,if functioning start to open around 82 degrees centigrade or so.
Hope this helps!

sounds like coil problem, coils will start cold then get hot and stop. when coil cools will crank up and run till it gets hot, try to replace the ignition coil,dont think it would be a crank sensor, try a coil,thanks robert b.

sounds like you head gasket problem or maybe cooling system needs to be bleed.

FUEL PUMP MIGHT NOT WORK. CHECK TO SEE IF IT HAS SPARK.

If you were experiencing a failure just after a heating cycle but not on a cold start, I would suspect an electrical component failure. As the component cools, it makes contact and allows the furnace to operate. This will change and not for the better. Depending on what your system has for electrical components, I suspect either a relay or transformer. At any rate, get a technician in front of it so he/she can diagnosis it under both cold start and hot start conditions. It will help if you turn off your system so it will be cool when the tech gets there.
