The way to test a fuel pump is to put a pressure gauge on it in the morning when it is cold when you have the problem. If the pressure is low then your fuel pump isn't working when it is energized.

If it is high, but it is still hard to start, look at a fuel injector being plugged up.

I find it hard to start my l 200 after running several minutes.i could start it in the morning after I on the switch what ,s the problem.


May just be a bad temperature sending unit. Once warmed up, it's supposed to go off cold start, which puts more fuel to the engine. If sending unit is not telling the computer the engine is warm, it will still be putting more fuel into the engine and flooding it, making it hard to start. Check/replace said sending unit and you're good.

Hot starting problems are usually fuel related. When a hot engine is shut off, the temperature of the engine and everything on it continues to rise for awhile as the engine undergoes a period of "heat soak." This can cause fuel to boil inside the carburetor bowl, fuel lines and fuel filter. When you attempt to restart the engine, "vapor lock" obstructs the flow of fuel and the engine doesn't want to start.
This is much less of a problem on fuel injected engines because the fuel is usually under much higher pressure inside the injectors and fuel line. Even so, a fuel line routed near an exhaust manifold or a fuel rail that's exposed to a lot of heat may still suffer the same kind of problems.
Heat soak problems such as these can sometimes be cured by wrapping insulation around affected fuel lines, and/or installing an insulating spacer or heat shield under the carburetor.

My car still stop all of a sudden without any warning and then it will have a little bit of a hard time starting.


If it starts fine when cold or will restart after it cools down and run until the engine warms up, have your TPS (Throttle Position Sensor) replaced. I have seen quite a few lately that will "warm" up and cause the car/truck to gradually run rougher as the engine compartment heats up and once it sits and cools off will restart and run again. You can go to auto zone, advance auto, etc and have them run a free diagnostic test on your car and tell you for sure if any TPS trouble codes are stored

Hard to start cold but once running is ok


I believe you have a throtle body correct? IF so you have poor fuel pressure, plugged filter of injector.If by some miracle you have a carberated engine the the fuel is leaking from the bowl. Get a carb rebuild kit.

Hard to start on cold mornings but starts fine when warm


The cold start valve is not operating correctly. Either the engine coolant temperature sensor is bad or the cold start valve itself is bad. You can check the engine coolant temperature sensor by going to radio shack or any electronic store and purchase a 15k ohm or higher resistor. Disconnect the engine coolant temperature sensor (ECTS) harness. Bridge the 2 female spade connections in the harness with the resistor. Start the engine. If the engine starts you need to replace the ECTS. If the engine is still hard to start, you need to remove the cold start valve, (wear safety goggles, and whatever you do don't smoke) place the cold start valve in a glass and have someone crank the engine. You should see gas coming out from the cold start valve. If not take a ohm meter and measure the terminal at the cold start valve after disconnecting the wire harness. The meter should read 25 ohms. If it doesn't replace the cold start valve.

Possibly a Battery going bad, check your connections, if they are tight then you may need a new batter, if they are loose, then tighten them. (If the problem persists after tightening, have battery checked)
