Have a 2003 Mazda Tribute having intermittent starting problems. It will turn over but not start. Also it will die while driving every now and then. Have replaced IAC, fuel filter, and fuel pump works fine. Cannot figure out what is wrong.

Check the Fuel injection system (injectors) and the intake manifold. It might also be wise to check the alternator as well as the starter coil and also the electronic distributor

Try using a good fuel line/injector cleaner Seafoam is a good one. If this does not help you may have tone or more clogged injectors. Clean these out and you should be good to go. tTo see Seafoam in action goto you tube type Seafoam into the search box.

try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.

Then you have a intermittent spark . Now do you have a spark tester to test spark. Its okay if you dont we have one . Oh by the way you did the fuel pump yourself. if you can do a fuel pump then you can do this to solve the no start problem. No spark tester? okay we will use that tachometer (RPM gauge). crank the engine does the tach meter reads zero at all times while cranking, if it does youll need a crank sensor. Here the story Rough running conditions and or stalling was caused by a faulty crank sensor, try shaking the connector or wiggle the crank connector then see if it starts. Youll need to inspect the connection for proper male to female connection these have been the most suspectable failure of KIA. If you decide to replace this sensor make sure connections are good, more than likely this was the problem and not the fuel pump
