Question about 2000 Ford Ranger SuperCab
My 2000 Ford Ranger seems to have starting problems only after I have driven it. It becomes hard to (sometimes impossible) to start. I recently replaced the fuel pump and filter, because I thought it was the problem, but I'm still having trouble starting it after I have driven it and the motor is cooled back down. Any idea what causes this problem? It usually takes 2 or 3 tries to get it going and it sounds bad, like the motor is struggling, sometimes it won't start at all. but if I let it sit overnight, it usually cranks right up in the morning!
Unfortunately there are many things that could be causing this. I would check the engine coolant temp. sensor ..and see what its reading with the engine hot. Your going to need a scan tool to get that reading...or just change the sensor...good luck

The check valve is a small brass fitting where the return line attaches to the filter head. I believe it takes a 7/16" wrench. There is a 'duck bill' inside that prevents fuel from leaking back to the tank causing air in the system. It should allow flow in only on direction. Some times you can see light through it if it's bad enough. Also, the lines between the injectors can dry out and start to leak air. Air will leak in before fuel leaks out, and you won't see it. There are plastic, cup-shaped connectors for these hoses that press onto the top of each injector. They are sealed by two o-rings on each injector body where it meets the connector. These o-rings can dry out and also leak air and fuel. Your Ford dealer or diesel service professional should have the proper o-rings. Any other o-rings might not seal, as they won't be the exact size. You already changed the fuel solenoid when you replaced the pump. It is inside. There has to be battery cranking voltage to it while cranking, and battery voltage with key in 'on' position. The wire attaches to the top of the pump. This is not likely to be the problem, since it restarts every 2 hours.

No not the fuel pump. You most likely need to do a tune uo. New spark plugs, wires, fuel filter, air filter. Deffinently change out the spark plugs. I would suggest using autocraft, autolite (fords brand} or some densos or ngk for better performance. Hope this solves your problem.

it's your upper intake manifold gasket. it has a crack in it and needs to be replaced. your getting to much air and not enough gas. mine did the same thing.
