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.

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?
