#7 of 26 2002 Santa Fe hesitates at Start-up by ruspy1

Jul 15, 2009 (7:15 am)

I had the Timing belt and the Alternator replaced. The Timing Belt was due to be replaced at 60k. I noticed that there was a whining noise, thinking it maybe the Timing belt, which I had it changed at 63k; however, the Hyundai Service informed me that the whining noise was the Alternator, it was on its way out, and the bearings caused the noise. My Santa Fe was occasionally hesitating during start-up, I'm thinking it was the Timing belt or Alternator, however, I had both of them replaced and car still hesitates during start-up sometime when sits for a while. Called Hyundai service and explained that the Santa Fe still hesitates during start-up after replacing the Timing Belt and the Alternator, could it be the Spark plugs that needs a Tune-up, he said that the Santa Fe doesn't need a Tune-up until reaches 80k, where I'm at 63K miles. He thinks that the Battery needs to be recharged because the Alternator was defective and replaced. I'm still not convinced, because the car hesitates during start-up and runs rough for little while before it warms up. I still think it may need a Tune-up. Has anyone had a similar problem?

I have a 2002 Santa Fe aprox. 120,000 miles. A while ago the car started hesitating (jumping mildly) at 40-45 mph. Then one day, at normal driving speeds, started severly hesitating (feeling like it was choking out) and stoped running and would not start up. After towing to a mechanic who did not find the problem because it would not act up for him, I continued to drive it for a month or so with no problems until now. It drives fine for a few miles then chokes out and stops running, won't start back up unless it sits overningt. Then this patern is repeated. I have put a fuel pump in it but that was not the problem. Any solutions out there?

I get a bearing noise when driving at 65-75mph but die out when I reach 80mph. The noise actual builds up on 3rd gear and worse at 65+ mph.

#12 of 26 Hyundai Santa Fe hard starting, rough idle by psykoconnell

2001 GLS 2.7 V6, 103K miles. Did waterpump and timing belt back in August. Just did spark plugs and new plug wires a couple weeks ago. Ever since then, the car has to crank over for up to 10 seconds now before starting, and it's starting really rough, either too much fuel or not enough. Smells more like too much. Also, at idle, it cuts out a bit every now and then, idling rough. Accelerates and drives totally fine, just at idle, whether in nuetral or in gear. Bad injector maybe? Malfunctioning PCM? Fuel pump takin a dump? Or did I screw up the valves because the timing belt slipped 1 cog on the cam gear and it's an interference motor (which I've already fixed, now problem seems to be getting worse)? Also, now the cruise control won't turn on....is it linked in somewhere and not turning on because of the rough idling/starting problem? can anyone help?
 
 *Also, the car is NOT showing check engine light and has NO codes."

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 it’s 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 by empowernv

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?
