1999 Silverado V-6 4.3L I changed the camshaft sensor the fuel pump the ignition control module today. After that has rough start b/n 10-30 mph but smooths out but engine light flashes from 25 mph on


If your original problem was low fuel pressure recheck pressure and check for flooding of gas in the intake. These models have a bad problem with the plastic tubing feeding the fuel injectors and you might be looking at replacing the injector assembly. If ok check for sticking egr valve or intake leak.

The van was running fine... Now it seems to be flooding itself. It will start but runs very rough. What should I do?


I would check the air cleaner and replace it just to start...
What you are saying sounds like a faulty injector that is stuck open... But a plugged up air cleaner could do this too...

After my chevy is warmed up, it will not start unless I put the gas pedal to floor.And rpm goes up


If it is running rough or dies after you are running or you turn it off and try and start it and it acts as if it is flooding then sounds like you have a bad temperature sender. It is not showing the computer that the engine is warmed up and is telling the computer that it is still in cold state and is giving more fuel to try and start. Need to change your temperature sender.

My two daughters each have a cavalier, one is 1998 and the other is a 1999. Both vehicles seem to have the same problem - turn ignition (no problem with battery), engine will crank but will not start,...


Hi Tony,
When you are pushing on the gas pedal you are not giving it gas anymore,That is a throttle body,you are giving it more air!
You need to check and probably replace the ECT switch.
you need to have the Engine Coolant Temperature switch checked,since the computer relies solely on sensors,the ect tells the computer how cold or hot it is so the computer will make it a rich or lean mixture to start the engine,if it tells the computer that it is 75 degrees the computer will lean the mixture like starting a car in the winter without a choke.

The 1996 Chev Cavalier runs great. Then I stop,


It sounds like the fuel pressure regulator has gone bad and needs to be replaced. Start with that if your engine is flooding over with gas as you ****. If there is an Auto Zone around you area, have them scan the car for any DTC codes that may be related to your car not starting like a bad MAP sensor which would also cause a no start when the engine is hot. Auto Zone also carries the parts you will need to replace and can give you the step by step instructions to replacing the parts with common tools. If your good with tool both job should take about 30 min to replace. Good luck and keep me posted
