#13 of 26 Re: Hyundai Santa Fe hard starting, rough idle [psykoconnell]

I found a light at the end of a tunnel (another forum). FUEL PRESSURE REGULATOR. It's vacuum operated so when the diaphram starts leaking, it's three problems together....incorrect fuel pressure monitoring, vacuum leak, and pulling unmetered fuel directly into the intake manifold and causing the car to run rich (which would also be like the car is choking out because of too much fuel). Best part is, fuel pressure regulator is only $35 or so, found it on Amazon.com
For that price, I would say itís worth it to change out, especially 200-2003 year Hyundais.

Thanks for this tip. Changed the Fuel Pressure Reg. on my 2005 santa fe 3.5L and this was the issue. Easy and cheap fix and now runs like new again!
#16 of 26 2010 intermittently won't start
Nov 22, 2011 (9:57 am)
For a few days now, the car either starts normally, or I have to shake rattle and roll with gear shift, key in collar, etc. (I have no idea which of these might be helping, but they make me feel better) to get it to 'catch'.
Radio and fan and indicator lights all come on; and sometimes it starts to turn over. I've been able to get it to GO but right now status is NO GO
Of course I have appt at dealer shop tomorrow - but I need to get through today -
Anything I can do on my own?
#17 of 26 03 Santa Fe "Will not communicate" code on scan tool
Nov 22, 2011 (4:13 pm)
My 03 Santa Fe has been very well maintained, has a new battery and full tank of gas. Driving out of my neighborhood two days ago the engine died and would not restart. When I turned the key to start it I can hear the fuel pump priming and there is plenty of battery power to crank the engine, but it wont take a spark. Had vehicle towed to mechanic and he hooked it up to scanner and the code read "will not communicate" Does this code indicate a bad ECM or some other computer related problem? If it is a bad ECM, how costly and difficult is that repair? Any thoughts or suggestions would be much appreciated. Thank you.

#20 of 26 Hyundai Santa Fe difficulty starting in morning
Dec 29, 2011 (8:17 am)
My '08 2.7 has difficuly starting in the morning. It makes the normal cranking noises but won't fire up immediatly. I typically let it try to catch for 5-10 seconds, pause, and try again. Then I wait a minute, try again, and everything starts fine. Then it'll start normally the rest of the day.
Pardon my ignorance, but isn't there some sort of compartment that holds fuel into the engine with a check valve that keeps it from releasing back into the tank? Could it be that this valve is leaking?
Or does it sound like I need a whole new fuel pump?
Any help would be very much appreciated.
#21 of 26 Squeal, Stop, and Smoke
Jan 07, 2012 (2:25 pm)
On Jan. 4th, my Santa Fe 2002 was driving along fine and all of a sudden it started squealing and completely shut off...It started right back up and began to squeal even louder and then I smelled something burning and saw smoke...I happen to be next to a large parking lot... I immediately drove it into a parking spot and turned it off...Had it towed home dreading that this must be an expensive fix...Any ideas as to what this could be??? Engine light never came on...Working overtime now trying to get cash together before I take it to the dealer(dealer maintained since 2002)...Thanks

Hard to say - maybe just the serpentine belt needs to be replaced?
