Is it something I can repair? Where is the starter and what can I expect to pay for it?

trying to fix a starting issue

It seems as though no one has this answered. And I don't either, sorry. I have the same problem now w/ my 2007 Buick Rendezvous w/ 125,000 miles on it. I just had the transmission fluid & filter changed and it still happens occasionally. Everything seemed to go awry when I had a damaged left headlight replaced from accident. I get the no seat belt usage gong one time every 7/10ths of a mile plus then the gong sounds again for every left turn signal pulse until I use the right turn signal which extinguishes it until the 7/10ths bit starts it again. It's just aggravating from such a fine automobile(CXL). My only conclusion which "I" believe it may be is the computer. At times I mistakenly blame others. Did the dealer change out the computer because another vehicle has the gong problem? I'm frustrated as you are. Hopefully you and others can view this response. I hate buying new cars. 0730hrs 22mar2015

Fuse is fine. Replaced both the door lock system and controll unit for power windows. Still didn't work

Has been to dealer twice in two months, cleared old codes never acted up for dealer a total of seven days. Now today it quit while driving and the mechanic tells me it's the fuel pump and he recommends an AC Delco $400 fuel pump because the$250 ones are junk. I always though fuel pumps just go out, not work part of the time. HELP

We changed the fluid to correct a chattering of the transmission. When accelerating after a red light the transmission slams into gear making it feel like someone hit us from behind. It seems most notable after a long ride then a stop at a red light. We changed out the fluid through the dip stick to take care of a chattering situation during the same set of circumstances. Now it slams. Not every time but most of the time.

We changed the belt, and the battery and the problem still exists. When we accelerate on an incline seems to be the most noticeable.

Trying to start the car and it won't start unless we press the gas pedal down some. We like to use remote start in winter and this will be a major issue if we have to be in the car to press the pedal down. It even does it on warm starts as well.

The car hesitated and then wouldn't run. Replaced the fuel pump and it ran once then tries to turn over but won't. What is the problem?

has new alt. battery is getting worse

120K MILES ...well maintained and no problems. Just died while idling at light. Towed. Left overnight. Garage started up fine this morning. Told need new fuel pump ASSEMBLY and that they are very expensive - ? Oil fine, battery fine. NO dash lights came on. Any other ideas before I part with $$$$$$$ Thanks!
