What cause the engine to run rich and black smoke coming from tail pipe?


hmmm sounds like the fuel pump is more of the issue as its sending too much fuel into the motor making it run rich or the gas that your using is too rich for the motor itself

Gas smell coming from my tail pipes


There are some safeguards which diagnose rich fuel conditions. If you have a hybrid which has a start-stop feature, this may be a reason for the smell.

Have someone check underneath the car for fuel line leaks just in case. If the system is running rich, a warning will appear. Sometimes old gas will make the exhaust smell stronger and if you used the E85 there will be more odor.

1994 Blazer 4.3 keeps stalling out running rich smells like gas


Leaking fuel pressure regulator , or leaking injector's ,depends on injection system . ! it's only running rich on right bank. whatever that means . Your vehicle is a v - 6 has two banks . right side of the engine an left side of the engine . Bank 1 is where #1 spark plug is . bank 1 is odd numbers 1-3-5 Bank 2 is even firing #'s 2-4-6 . What fuel injection system does it have ?
Your best bet mite be to take your vehicle to a qualified repair shop.

I have an 89 ford bronco 2 with a 2.9 liter it sat around for 2 years without being started. I replaced the plugs, rotor, cap, ran fuel injector cleaner through it several times, checked cylider...


check the spark plug wires are attached all the way till it snaps, pull each spark plugs, any black deposits on any plug means it isn't firing(faulty plug,or wire) last of all take off each injector wire and notice if there is a change in idle speed (plugged injector)
