bought an 05 equinox with 17000 miles on it in 07. was bought for my wife as a daily driver and for trips to relieve my pick-up. late 07 i believe, we started having trouble starting the car. turn the key, engine would turn over and continue without key in start position. found out that was suppose to happen so we were told. how ever car wouldn't start. next time car would start no problem. after repeated times we took it in for the service tech to look at the problem. didn't know. told us to try injector cleaner and see what happened. continued to have the same problem. never would do it at the sevice dept. finally wife got stuck one time. tried starting for 15 mins. nothing. i told her i will pick her up and called the service dept. to pick it up. did it once to them. changed the fuel pump and checked voltage. no voltage prob. continued to have prob. left it with them a full week. no prob with them. we are not crazy. got it back. was also told before to wait 3 secs. in run position to let fuel system prim up then start. continued to have prob. cleaned throtle body and replaced k&n air cleaner i had in it whitch i put on after probs started. now has factory cleaner in it again. still have probs with the same issue. do i have a lemmon or does anyone have an answer to our probs with starting this car. ready to take a lose on balanc and get rid of it.

My girlfriend's 06 equinox with 53000 miles does the extending cranking like you talk about and has since about 30000 miles. She bought the car new. It does it maybe 2 times a month... sometimes not for months on end. It has never left her stranded. To me it sounds like the computer is not telling the car to either a) fire the coil or b) pump the fuel. I'm not a mechanic but I think it's a ignition/computer issue.

Thanks for the reply. I will pass that on to my service tech. Also when the event does happen it's not leaving a log on the computer to read later. We are also going to try a different gas station and see if that does anything.

Does the extended cranking only happen when the nox engine is warm? Or will it happen when stone cold also?

It occurs both warm and cold. It always starts on the next attempt. I've seen it happen with all brands of fuel. Full fuel tanks and tanks less than full. Perhaps for some reason it is vapor-locking.

temparature gauge by laserblue

I noticed that my coolant is still low in my recovery tank.
The dealer changed the head gasket 2 months ago because the coolant was always low. Now it's still going somewhere + it's now changing color from orange to brown and + there's a white milky residue (looks like mayonnaise) sticking on the interior side of the recovery tank that wasn't there before the gasket job.
I also noticed that my temperature gauge rises faster than usual.
 What do you think?

Sounds like there is a crack in the head or block. When coolant mixes with oil it turns a milky white light tan color.
  Does your temp level gauge read hotter than before or does it run cooler. You can have a sample of your oil checked for coolant in the oil , if it's not brown too dark brown then you probable have an internal problem with a hidden crack in the engines coolant passages bleeding into the oil. Has your oil level gone up at all since the head gasket was replaced.

My temperature level gauge is at the same point as before but it seems to rise faster than usual, but stops at the same spot as it always been, never over heated. Only once it went a bit higher than usual but I was in heavy traffic, once I started to move it came back to its normal spot.
When the dealer changed the head gasket 2,000 km ago they had to change the oil and coolant also. The oil looks normal, a bit brown but normal for a 2000 km oil. The oil level is right a the full mark on the dipstick.
 The week after they had changed the head gasket I called the dealer because I could hear a clicking sound every time I started the truck (cold start) the same clicking sound as a muffler cooling down but the sound came from under the hood.
  They said that it was normal, that it was caused by the different torque on the bolts or the bolts were warming up.
  I told him that it was pretty strange because it never did that before they worked on it and I had 49,000 km.

Just came back from the dealer.
 
  They checked everything with a special light to see if the antifreeze was leaking from somewhere. Everything is o.k.
  They said that probably there was air bubbles in the system when they replaced the head and valve gasket and they went up in my recovery tank and that's how the antifreeze's level went down. They toped off the coolant to it's full level.
  For the color change...they told me that it's probably dirt coming from the system that went in my antifreeze.
  Than for the white, milky substance... it's formed by a dirt ring on my plastic recovery tank and with the movement it mixed with the antifreeze and settled on the side of the tank.
 
  They recommended me to do a "cooling system flush and cleaning" in the future but that it was not urgent.

Well that's good news . You can drain the coolant from the system the old fashion way. Just open up the cap to the surge tank then go under the truck and find the drain valve cock on the bottom left side of the radiator . Open it and let gravity drain out the system , have a large pan to catch as much of the coolant as possible, it can be recycled. This can take Fithteen minutes or so ,close off the drain cock on the rad and start the refilling the system with 50/50 GM DexCool antifreeze and distilled water, it doesn't have hard water minerals that will plug up the small passages ways for the coolant a big problem that's over looked .
 
 Open the air bleed screw on the water pump tower, slowly pour the new coolant into the surge tank and watch until the coolant begins to seep from the air bleed screw. Then close the screw and continue to fill the cooling system until full, install surge tank cap. Run the engine from idle to 3000 rpm in 30 second intervals until the engine cooling fan comes on then idle for 30 seconds and turn off engine.
  Allow the vehicle to cool add coolant to the recovery tank until the level is just above the cold level line . Install surge tank cap. The system should approx 5 liters of coolant.
  This method will not over pressurize the cooling system that can happen with a pressure flush method used in most shops. The coolant will be a bright orange and should be tested for the freezing point of at least -25 to -30C.
  
It's quite easy to change the coolant just takes some time and the proper fluids and will save you money.
