If your 1997 Ford Explorer is flooding and won't start even after replacing the fuel pump, the issue could be related to a faulty fuel pressure regulator, a malfunctioning fuel injector, or a problem with the engine's ignition system. Check for any fuel leaks, as well as the condition of the spark plugs and ignition coils. Additionally, ensure that the fuel filter is not clogged and that the fuel lines are in good condition. If the problem persists, consider running a diagnostic to check for error codes that might indicate the underlying issue.
Its the cold start fuel sensor giving you troubles. Its flooding the engine with fuel.
does it start without the choke? if it does you are probably flooding the engine with the choke readjust it
You can prevent fuel injection flooding by not pumping the gas pedal when trying to start the engine. Fuel injection systems do not need any additional fuel when starting the engine.
It is getting fuel/spark/ compression?
you will replace the timing chain when mornig cold start becomes noisy Normally it will last the life of the engine, and is replaced when the engine is overhauled.
engine flooding. low battery. cold weather. try putting the holding the clutch down as you start the car as this takes some of the pressure off the engine
sometimes when you change out a fuel filter on those they get a vapor lock make sure the engine is getting gas if not try pumping it a few times till you can smell gas under the hood then do not try to start it let it sit for an hour what you are doing is basically flooding the engine to push out the air in the gas lines to let the pump do the work now after and hour try to start the truck normally and should start
If you have spark, you have fuel and you have compression, It will start. Backtrack and find which is not happening. You might also want to check your timing because you can have fuel,spark and compression, but if the engine is out of time it will not start. The timing has to be close for it to start
"was having charging system problem so alternator was replaced now car keeps flooding and won`t fire.
It will for maybe 3 seconds , when the key is turned to the run position , before you start the Explorer
