93 park ave.irs stuttering and it dies when u put it in drive


Could be anything from stuck on Tcc solenoid to a faulty fuel pump. May have enough fuel pressue to start but not run under load. TCC is in transmission and controls converter lockup if it happens at a stop it will shut the car off. My bet would be on the fuel pump. Check the fuel pressure and volume spec in a chilton book and install a fuel pressure guage to insure that it us at spec. Fuel pressure guages can be bought at any chain autoparts store there is a shrader valve on fuel rail that it hooks up to. Be sure to take all saftey precautions when using this.

My 96 buick park ave won't start n cold weather why


Could be a long list of possible causes.
Have you had the spark and fuel pressure checked ? It takes more fuel and more spark to start an engine in cold weather.

My 93 bravada wont start new fuel pump and injector


I'm guessing from your short statement that you are not getting fuel. Your '93 would have either the 2.8 or the 4.3 v6. If your not getting fuel, check the fuel pump relay, look for a blown fuse. Disconnect the oil pressure sensor and jump across the connector terminals and try to start the engine. If the oil pressure sensor is bad, it will shut the fuel pump off.

My 1994 park ave, sometimes it starts, sometimes it wont, it does not matter if is is hot or cold, when it is running it runs smooth like there's nothing wrong. I replaced most of the fuel system, spark...


You have three choices. First, check the spark and coil system to ensure you are getting a spark. Pull off a plug wire from the coil pack and crank. Have someone watch to see sparks snapping off the coil pack. If you don't have any replace the control module under the coil packs.

Second, you may not be getting enough fuel pressure. Put a gauge on the fuel pressure test port. You may have a bad oil pressure sensor, located down above the oil filter. Check that oil pressure sender and make sure the connector is pushed in. The power to the fuel pump runs through the oil sender. If the engine starts and oil pressure doesn't come up quickly, the computer will shut off the fuel pump. Check this and you can also manually engage the fuel pump from the relay block down by the passenger feet.

Third choice, and it's a long shot, check the harmonic balancer and the crank position sensor. If the sensor is bad, the computer has no idea when to fire the spark plugs. A magnet is on the harmonic balancer and flys by a sensor to induce a voltage in the coil and tell the computer what position the crank is in.

You also may have a bad computer.

You can figure it out.

How do I change Spark plugs?


93 park ave has a v8. Four plugs on each side. Followthe spark plugs from top of engine to spark plugs. Use a spark plug wire remover (plastic pliers) to help remove wire from plug. Mark each wire where they go. Go down to auto store and buy pugs and get a swivel spark plug wrench to fit the plugs anduse a extension with rachet to remove plugs (turn counter-clockwise to remove). Replace with new. (new plugs should screw in with fingers, then tighen with socket firmly. Not over tight. I holp this helps a little - ran out of writing space. Good luck
