Could be the oxygen sensor or a blocked air filter as well.

My new spark plugs are getting wet, and tail pipe has water coming out of it?


Getting water in the tail pipe is a good sign as the engine will always have moisture when not running. Water on spark plugs is a bad sign as there may be a leak from a cracked cylinder head which is then a major job, the car should be running erratically or will stop.



To check if this is the case take out the oil dipstick and see if the oil is light brown instead of black then you have a problem as mentioned so needs major overall to the engine.

was it doing this before you changed them? something is wrong with your firing, recheck firing order. could be a component you swapped in is faulty. if it was doing this before you changed them check crank sensor and lambda sensor

Cranking over but wont start


If you smell fuel in the exhaust, then you can assume the fuel pump is working. Spark at the coil is fine but do you have spark to the plugs? It sounds like you have an older car with a cap and rotor. You might have a bad cap or rotor. It might just be flooded, in which case pulling and cleaning the spark plugs would help.

this is a code for misfiring ( cylinder #4). you need to reset engine computer first. you can do this by removing negative cable from battery and waiting for 15 minutes. if there is save your radio code.

if it returns back, faulty cable for spark plug, old spark plugs, coil(s) may cause this. replace spark plugs first(it is the chepaest fix). mostly you can cure problem by this way. if not your oxygen sensor can cause this. you can understand this by running engine and observing how it idles and how it smells at back. if it start to idle rough and start to smell bad ad exhaust pipe. o2 sensor is gone.

you need to proceed step by step. 1 variable at a time please.

in extreme cases burned exhaust valve,or broken ECU can casue this too.(very rare)

If you smell fuel in the exhaust the vehicle is flooding or there is no spark. If it is a carb engine, make sure that the choke is in and hold you foot flat on the pedal while trying to start, this will clear any flooding.

Ok i recently changed spark plugs on my 1994 buick skylark. when i was done changing plugs i started car up and smelled strong exhaust smell. so i checked the plugs wires and found out that when i pulled...


Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....

1996 gmc sierra, have changed fuel pump and fuel filter. can smell plenty of gas coming out of exhaust pipe. tested for spark, have spark.. truck will crank but not start. what can i try or check now?


Check the timing and make sure the battery is good, the battery can sometime have the power to crank the engine but have internal problems that leave it without enough voltage to give you a hot enough spark to start the engine.
You could also have some bad ignition parts which could be shorting out your spark or sending it to the wrong spark plugs. Plus you could also have fouled spark plugs.

My Dodge Caravan 1998, was running good, i parked the van for 25 minutes, When came back, don't wanted start. I already change the gas pump, the battery, crank sensor, spark plugs... What can i do now?


You need to do some analysis. An engine requires fuel and compression to start and run. If there is no compression, the sound of the cranking is very different. Since you did not mention that, I suspect that is not an issue.

Smell the exhaust pipe, then crank for a while. Smell the exhaust pipe again to see if there is a gasoline smell. (Don't put your head near the exhaust while cranking; if the engine happens to light off, or even if it just gets a little flame into the exhaust, you can be injured by the exhaust.)

If there is no increase in gasoline smell, you probably are not getting and fuel to the engine. You can try, in that case, spraying some starting fluid into the intake to see if that cause the engine to start briefly. If it does, you know for sure that the mechanical and the electrical aspects of the engine are functioning.

Pull a park plug out of the engine, put the plug back into the boot at the end of the plug wire, lay it on the metal of the engine. Then have one person crank the engine, and check to see if there is a stout spark in the gap of that plug. If not, you have an ignition problem: Bad coil, connection has fallen off the coil, bad ignition switch, etc.

One thing that can cause this kind of abrupt, complete failure is for the timing belt to break. If your engine has a timing belt, visually establish that it is going around with the engine.

1991 toyota 3L V6 Overfueling, raw fuel pouring out exhaust pipes


check if your O2 sensor is working that is the thing telling computer how much fuel to put into motor it is on pipe close to motor your O2 sensor tests how much oxygen is pipe while running and tells to increase or lean back fuel
