I had posted before about my Carry suddenly running rough and then having fuel dripping out of the exhaust. Today I finally was able to look at the engine better to see what was going on. I pulled the dip stick and smelled gasoline in the oil. I then pulled all the sparkplugs and they all looked good, but the rear cylinder(I think #3) had gasoline on the plug and in the cylinder. I turned over the engine and a ton of gasoline came out of the cylinder. I then put a inline sparktester between the #3 plug and coil, started the engine and had very good spark which increased with higher revs. It seems like the fuel injector is putting way to much fuel into the cylinder. What could cause this flooding? I can't run this engine until it is fixed and I still need to drain and replace the oil and filter since they are contaminated with gasoline. Other than this issue, which happened suddenly, the engine starts right up and runs fine except for the rougher running from the overly rich mixture on the back cylinder. The other possibility is the sparkplug itself might be bad somehow, but it looks fine. Any help or suggestions here would be appreciated, as I have no idea what would cause this.
Pull the injector, turn the key on, does it continue to shoot fuel or just a little. Does it shoot fuel after the key is turned off? Compare it with a different cylinder. Injector/fuel pump or throttle body is my thoughts. You could also switch the injector to a different cylinder and see if that cylinder fails.
Thanks Woodhe1! How easy is it to pull the injector? I also had someone suggest putting a Noid light on it to see if it was getting pulses of power or instead a constant light which would suggest a bad ECM. I will give this a try as soon as the weather drys out again, as we have thunderstorms here right now, and it is not under cover.
