2004 Santa Fe starting issue

Greetings. I have an '04 Santa Fe. I've begun to notice a starting
problem when it's cold (the engine, not the environment). It cranks
and cranks, but unless I encourage it with some serious gas-pedal
pumping, it won't start. Once started, it seems fine. If I try to
restart it right after it's been running, it has no trouble.

My mechanic (not a dealer mechanic, but very reliable; been going to
him for 20 years) can't figure it out. He took it to a different shop
he's worked with before; they couldn't figure it out. I'm now taking
it to a dealer, but the experience so far doesn't fill me with
confidence.

Anyone got any ideas? I don't want to be driving a rental car for much
longer.

I'm not a mechanic, but it sounds like a fuel system problem to me.
Check the lines, fuel pump, fuel filter to start. Good luck.

Regards,
Bob

 

Sounds like you have trouble with the cold start circuit. My guess is
that the thermo sensor for the system is not working well.

I doubt that pumping the pedal has much effect on the engine start since
there's no carburetor and no accelerator pump to shoot raw gas into the
engine. Just hold the throttle part way open to crack open the throttle.

 

It's hard to say, but I'd imagine if the problem can be replicated
during testing, they should be able to find the issue. My initial
guess would be fuel pressure bleed-off due to a faulty regulator. But
that's just a guess-- I'm not looking at the car.

If you're still paying attention to this thread, which engine do you
have?

 

Did you get it solved, what was the reason for that, please reply me ASAP

 

My 2004, 80000 mile, Santa Fe refused to start today. I've had it 11 days and driven roughly 1000 miles including 130 towing a caravan, with no trouble at all. However today I tried to start it, and had no luck. It started to engage then disengaged from the starter motor The starter didn't engage I gave the motor a couple of whacks and eventually it did engage, but refused to start The malfunction indicator is lit but as the engine isn't catching I'm not sure whether the ! is indicating a fault or not. The fuel filter indicator is also lit, but again I don't know if it's because the engine isn't running. The previous owner had it regularly serviced: I have all the reports. It seems to possibly be the same problem as Shane, above.
