My Hyundai Xg350 will not start in the cold.


Depending on how cold you are talking, it could be water in your fuel system freezing and blocking the fuel delivery, do you know if you are getting fuel to the engine when this problem occurs?
You can try a fuel conditioner one that removes water from the fuel system but is safe for injectors and see if that helps.

I have a 2006 Freestar with a 3.9 Engine . When it is cold it has a miss when i step on it. But it gets better when it starts to warm up. Almost seems like a spark plug miss


Spark Plugs ---change at 70,000 miles
O2 Sensors--change at 100,000 miles (front 2 only)
Gas Filter--every 3 years/30,000 miles
Air Filter ---every 3 years/blow off once every year
MAF Sensor---Clean once a year or more often

Ignition Coils--- most definitely will go bad,at
least 1 a year. (Any Check Lights or Codes ? )

When cold, it isn't in closed-loop, and runs on
Long Term Fuel Trim--not on O2 Sensors ,until
warm

Let it warm up at least 4 minutes in cold weather,
go light on the gas for first 2 miles

Hard start when hot 98 ford windstar with 3.8


Try replacing the fuel filter also Has it had a tune up? they need to have the plugs replaced at 100,000 if the fuel filter does not work then the most probable cause is the fuel pump is losing pressure when hot. The pump warms up and the check valve fails to close all the way allowing a now fuel or fuel starvation.

1991Chevy Lumina does not start


I didnt see it in your list, so I would suggest the O2 sensor, usally found on the exhuast pipe near the engine or on the back of the engine

THE FUEL PUMP IS LOCATED IN THE FUEL TANK. IF IT IS WORKING YOU WILL BE ABLE TO HEAR IT SQUEALING WHEN THE KEY IS TURNED TO THE RUN POSITION PRIOR TO ACTUALLY STARTING THE VEHICLE. IT WILL BE A HIGH PITCH. IF NOT THEN THAT WOULD BE A STARTING POINT. ALSO FUEL INJECTED CARS HAVE A COLD START ENRICHMENT VALVE THAT COULD BE THE PROBLEM. THIS VALVE CAUSES A MOMENTARY FUEL RICH SITUATION SO THE ENGINE CAN START. IT IS BASICALLY A CHOKE FOR FUEL INJECTED ENGINES.
