Ok, so I didn't drive my Geo last week at all. Parked it on Friday morning the 16th and it sat all week last week until this morning when I went to move it out of the way. It fired up right away as usual but it wasn't running right. I opened the hood and found nothing visibly wrong, but it has no power, doesn't want to rev, and sounds like an old Volkswagen Beetle when you give it gas. You know, the old air cooled ones that had that odd sound to them... I have done nothing to the car for a week and a few days, everything works and it starts right up. Has good looking oil and coolant, all in their respective places with no leaks. All hoses and wires look good and nothing easily noticed as out of place. Sounds like it's missing/running on 2 cylinders though. We had family over for Christmas today so I didn't have time to look into it much more than that. After I get the garage straightened up a bit, I'm going to see if I can get it in and look at it. Any ideas??? Thanks |

Then it probably is. Sudden symptoms after sitting for a while suggest moisture has affected one of your cylinder's normal ignition. Check for a loose spark plug, bad spark plug wire, loose wire to distributor cap, a carbon tracked or broken contact under the distributor cap, or a bridged spark plug electrode. |

Sounds good, but now it won't start at all. It's been dry outside for a day and i was getting ready to start it up and get it in the garage to finish drying out and try to track down the problem. I go out, turn the key on, I can hear the fuel pump run. Crank but no start... Very unusual for this car... Has always started when called upon. Now it just cranks, sounds different to. Doesn't sound like it's trying to fire at all, maybe not getting spark on any of the cylinders now... Now I will have to try to dig around and find out that issue as well. Maybe later I will have to push it in the garage and figure it out. Have to get back to the daily grind first though... |

Would start with spark and see if you are getting any. |

I have spark to the plugs... I used an old plug to check for spark, pulled each individual wire, installed the old plug and checked for spark from the dist. I have not pulled the installed plugs to verify them yet. I can see the injector dropping fuel, it's not a spray, but it is putting out fuel. I'm not sure how much is supposed to come out at startup. I also opened the oil fill cap to verify the cam is rotating and it is... Next step I guess is to check the plugs that are installed and make sure they are good. Any other ideas? |

Normally the fuel spray is fine enough you can't see it spraying, it is just visible on the throttle plate. If you are seeing droplets then that is a problem. |

Did you first check for any set or stored DTCs (codes)? With it idling you can also pull each plug wire one at a time (use gloves and pliers) and see if there is any noticeable change. If you find a cylinder that doesn't change the way the engine is idling or doesn't change as much as the others, at least you have narrowed it down to something that cylinder. And, do a compression test. Edited by myredvert, Dec 27 2016, 03:58 PM.

Freegeo, I can see the fuel accumulate on the plate, I'm not sure if it's a mist or not, but there is enough to notice. It may be flooded out and/or fouled the plugs now, which is why I was on the path to pull my plugs and check them. That's all well and good myredvert, but it won't start... I have not checked codes, and I can not check the plugs at idle if it won't start... |

no problem, thanks for the info though... I got the garage cleaned up this morning so I can get the car in out of the weather. After it thaws out this afternoon, I will pull it in and take a look at the codes and plugs. |

Ok, so this morning I pulled the plugs. They are fairly wet. Also after using my USB powered bore scope, cylinder 1 is really wet , 2 and 3 are damp. I also noticed just how much crud is on top of my pistons... lol Judging by the above, I'm guessing that cylinder 1 is the one that wasn't firing. I'm going to pull the distributor and make sure contact points look good. When I checked on Monday, I had spark on all 3 wires so I'm not really sure what's up there... There are no error codes (other than the 12 code). On a side note, my dome light went out while trying to start the car the other day... Edited by Bannedfonz, Dec 29 2016, 07:47 AM.

Ok, so I had all the plugs pulled. So after I dried the cylinders out (#1 had a pool of gas and oil on top of the piston), dried the spark plugs off and put them back in, and put the old plug wires I had taken off when I bought the car back on, (just in case I had a bad wire). I tried to start it again. It tried to fire once but wouldn't take off, after that, it just cranked... It's not even trying to fire again. Just cranks, like trying to do a compression test. My thinking now is that my injector might be stuck open? As I stated earlier, it looks like a lot of fuel is being dumped into the plate at startup. That might also explain the pool of fuel on the piston in cylinder 1. Not sure why #1 is the one with the pool while the other 2 are just wet though. I'm going to pull the plugs again and see if #1 is flooded again, maybe switch wires with #2 and see if that changes anything. If not, I guess the injector theory is next...

Maybe this will work. The video doesn't play on my end but could just be my computer... Anyway, this is the best video I could get of the injector spray at start up. It is putting out enough fuel that it is pooling on the plate. Cylinder #1 still floods, and I double checked that I do have spark on all 3 cylinders. Is there any "easy" way to check the injector?

Unplug it and see if it will start with the pedal on the floor. It will probably start and run until the excess gas burns off. |

Ok, I fixed the video... On another train of thought... Is it more likely that, since when it started the last time, it felt like it only ran on 2 cylinders, that this may be an electrical problem? I have yet to look up the trace for the injector, but maybe the injector is good but something is telling it to dump too much fuel? Also wondering why only cylinder #1 is flooded? |
