Chevy HHR suddely not starting, cranks fine, runs great.

Yesterday my wife filled up with gas on the way to the airport. She said they when she got back in the car she had to turn the key twice before it would start.

Last night I would get in the car (2007 HHR 2.2 LT) and the car would crank like normal but never fire.

I messed with the gas peddle a bit while trying to start it and got it to start a couple of times. Also I tried to hook jumpers up to my truck even though the battery seems fine and it did not seem to make a difference.

Once running it ran great. I noticed that the check engine light did come on after I got it started that first time. When I would turn the engine off if I tried to restart imediately there was not a problem but if I wait a few minutes it was like starting the whole process over again.

Its a mystery to me as to why it can be so hard to start and require me to try 5 or 10 times but then run great once it actually starts.

Some other info is that it has not had a problem before, the gas was down to about 40 miles left when my wife filled it up, and the gas cap had not been put back on correctly.

From scouring the internet I see that if the gas cap is not securely tightened with alreast 3 clicks it can cause the engine light to come on.

I checked the fuses as well to make sure they were all plugged in well.

Also it seems like it might be the fuel pump in that it might not be priming the engine correctly. (that is my uneducated guess)

I do normally hear a little hum when I try to start the car and believe I was hearing it last night as well.

If the fuel pump was out would the car start at all and if so run so well? I added fuel cleaner to the gas last night and drove about 30 miles without any problems.

Just wont start. I appreciate any ideas??

  • I am just as stumped . I did learn something in your post that I dont even think the dealer knows....
    i had a problem with my engine light coming on periodically and then just going off....I told the dealer ,twice, exactly what happened(because we are currently under bumper to bumper warranty-so I dont miss ANYTHING that may be wrong lol) and I missed the appointments because it went back off and didnt feel like sitting there half the day for nothing. Point being that if they knew about the gas cap causing it if not put back on correctly , dont you think they would have mentioned it??
    We did associate it with getting gas, or running low....but didnt know what the deal was.

    Thanks for the information!!!:) I know now that we were right and it really wasnt a big deal.

    I own 2008 Chevy HHR. It has been a great car until recently. On a very hot day after I had been driving and restarting without problems the car would not restart. I even added gas thinking the gas gauge had a problem. Still no restart. GMC roadside took the car to a dealer and naturally it ran fine and restarted multiple times for them. Picked up car and drove for a day then it happened again. Back to dealer. Hooked up to scanner and still no codes showed a problem. Dealer had car for 4 days. Since we were on vacation, we got the car started and drove the 250 miles to home. Stopped at a Chevy dealer (where I had prchased the car) and after the car failed to start for them they took it in. Called and said the problem was solved and that it was the computer module. Covered under warranty. Drove for one day then the problem resurfaced. Had it towed again (GMC Roadside) back to the dealer. Now they say it is the fuse block uner the hood with a short. Whole thing has to be changed. This time the part has to be ordered from Lansing and is not covered. (Car has 53000 miles on it). Now I will be out 500 dollars and they still are not positive it will be fixed.

    I filled the car up when it was still running. After leaving the station the car had a bad missing problem, is now hard to start and has a surge problem. My husband unpluged the battery to reset the computer and that seamed to help some. Still have a starting problem and some problem getting it up to a good speed when going up a big hill.
  • same prob here---ill make this short n sweet.....its the POWER STEERING fuse #60 under the hood....mine keeps blowing, and car wont start-----cant figure it out either, so i keep the YELLOW #60 fuses in my glove box :(
  • Our 07 hhr just started this problem, keeps cranking, i turn the key back to off.
    then the next time i try it might start normally, but it might also do the same keep on cranking issue.
    once it starts it runs fine, really starting to worry my wife as she drives almost daily early in the morning.

    Have you thought about changing the gas filter and geting your fuel injectors cleaned?

    Might be the problem.
  • Thanks, will try that.
  • We recently had the same type issue with my wife 2008 HHR. After going through all the normal things I checked the fuel rail with the key on as you should have pressure there with the key in the on position. Was not getting any fuel there. Lucky me the fuel pump was covered and once replaced have not had an issue. This seems to be a common problem with the HHR as I have found a ton of other sites with people talking about the same issue.
  • I bought used with 30k on it.
    thank god that i am a ase certified master mechanic that has own shop.
    i has now been a year that i owned this junk pile.
    so far besides the noises,clanking,i replaced,brakes,rotors,tires,ignition switch,turnsignal switch,air bag light on and off,rear drums,other misc problems.
    called gm corperat and they basicly told me to get lost!!!!
    I will never buy or any of my customers or friend,family,to buy a gm product !!
    no wonder why they are bankrupt,with service like this!!!
  • Ive been having the same issues for 2 weeks now but the only time it does'nt crank is when it get below 45 degree's outside. If its close to 50 or above it cranks up great. I have talked to several GM mechanics and they are all stumped. The computer checks have all been without errors.
    I have gone over my wife's 07 HHR with a fine tooth comb and can not find any reason for the problem .... until tonight.
    I was looking thru a forum not in here and have found the same issue with a person who might have figured it out. He has an 07 as well and his mechanic installed a second ground wire from the engine block to a shock tower. His mechanic had found a ground drop in the system and once he added the extra, it went away and the car started.
    This makes sense due to my checking. I was checking my current from the battery to the relay box, I was getting maximum voltage to the relays but had a slight flux in power that I blew off has a poor meter connection. Tomorrow I will be checking all the ground connections again and looking at adding an additional ground cable off the block.
  • I am having the same issues and the dealership can't seem to find a problem because it starts for them did this fix your problem?

    No, it didn't fix the problem, I gave it back to the dealership. If yours is a burgundy 07 HHR standard shift it might be the same car....
  • Have you considered the posibility of Vapor Lock? Sometimes, when a car is driven in hot weather, then shut off for a short time, it will not restart for a period of time. Usually removing the gas cap will help resolve the vapor lock.

    My story, if you are interested...
    My first experience with vapor lock was when I was driving long distance on a highway. I stopped for gas, then a little later stopped at a rest stop, turned off the car, took care of the necessary bathroom needs, came out and got nothing when I turned the key. I called for a tow right away so I would not have to wait too long, and then I checked a number of things - yes, the battery cables were tightly connected and not corroded, all fuses were good, but it still was silent when I turned the key. I then removed the gas cap, and the car started right up. I called and cancelled the tow, and then drove the rest of the way home, problem solved.

    Almost the same with my car. Take it to work, on really hot days, I come out and the car won't start. I have it towed to the dealership, by the time they look at it, it starts. Has happened 3 times already, the garage can't fix it because the car starts for them so they can't get any codes. I hate this car, I can't go anywhere with it because it may not start.

    Hello kbalcom,

    I'm sorry you've experienced several occurrences of your HHR not starting. If you would send your full name, address, phone, VIN and the name of the dealership you wish to work with to socialmedia@gm.com (Attn: Marlea), I‘ll do my best to look into your concern further.

    I have a 2008 that is giving me the same problems. I keep bringing it to the dealership service center and getting the same answers. They always tell me it starts for them. They did a cleaning.r.thinking maybe it was clogged...no improvement. Now the l check engine light has come on a second time. You would think the dealership would give you answers.
