I figured out that when the temperature sensor connector is disconnected, it makes the gas volume less than what it was but not enough to make the engine running properly.ġ. This is a new spark plug, but just look what happened to it for running less than 15 minutes after I changed them all. As you can guess after removing spark plugs, again they are wet of gas. How do I know that probably this is the problem? Because when i'm removing the spark plugs they are wet of gas, and also when i make them dry and clean, the engine starts flawlessly in milliseconds, but it stays on mostly for less than 2 seconds. The volume of the gas is way more than normal, so it won't let the spark plugs to ignite the air/gas mixture. I've done lots of things that finally I've figured out that the problem is the volume of the gas that enters the combustion chamber. This was the last time that the engine was running without problem. I just drove for maybe half an hour and when I came back, I just let the engine run in idle to let the radiator jet fan to be turned off.īut suddenly I heard a spark sound again, that was way louder than the things that i've heard before, maybe like a small cracker. I said to myself, so I must change them but I didn't know that running around 15 km could end up in this mess. I parked the car in a dark place and I started the engine, so there were at least 6 places on wires that had clear sparks. Until I found out that i hear some spark sounds under the hood. The car was working properly, but I didn't know that the spark plugs' wires have been torn in some places. And the parts used when ALDL was used are only slightly above the old points and carburetor type engines.Ĭlick to expand.It's an OPEL vectra-A 1994 2.0i j89 5MT engine: 20NE and i have it at least for 8 years. The engine needs fuel and ignition to run. A modern OBD1 or OBD2 scanner is looking for something more than a number of pulses that repeat.Įven with or without ALDL or OBD the old time troubleshooting skills still work. The idea that the original ALDL flashed a dash light is why I don't think the adapter you want will help you out. Don't know if this will help or not but here is a link to how it was done back when ALDL was still used, hope it helps you. It's been many years since I even saw a car with an ALDL in it. Not all of the holes in the connector even had terminals in them. You shorted out two of the pins and watched the light flash to get the code. But back when GM cars used that type of port ALDL it used one of the dashboard lights to read the codes. Again I may be wrong, since I never worked on or with an Opel.
