Read the codes or have a parts store read them (often for free) and perhaps you will get a clue. Sure sounds as if you may have a dirty EGR.

ford runs entirely on vacuum so if you replaced all the above mentioned the issue most likely is vacuum dry-rotted lines etc... however if it is equipped with a fuel shut off locate it and pull it to reactivate the flow of fuel sounds most likely just that from having been an owner as well

What engine code is stored in the computer? You may have a bad TPS (throttle postioning sensor), or a bad O2 sensor. Auto Zone can retrieve the code for you, and tell you what sensor it is related to.

Are you try scanned the PCM to know if some fault codes are stored there? Are you check injectors? We recommend to de-pressurize your fuel system. Disconnect the power to your fuel pump, by either disconnecting it's power supply, or pulling the fuel pump fuse or relay. Once the fuel pump has no power, crank the engine for a few seconds. The engine might start, but should die a few seconds later. If it continues to idle, then you didn't disconnect your fuel pump.

Once the fuel system is de-pressurized, we can begin to remove various parts from the engine bay to help clear up room. On a typical system, there is a fuel feed, and fuel return. For these types of systems, you would need to disconnect both of the lines, and then disconnect the fuel pressure regulator. The fuel injectors are held in with clips that hold the harness to the injector. Remove these clips, and pop off the wiring harnesses. The fuel rail is held in with a few bolts. Remove these bolts, and then the fuel rail should be loose. Pull the fuel rail out of the intake manifold or cylinder head, and you can now easily remove the fuel injectors.

Couldn't start his but had 40 psi fuel pressure, but even though it turned over. Are you check crankshaft, this is located crank sensor under the a/c compressor, to the left of the balancer. The camshaft sensor is in the timing cover usually behing the PS (Power Steering) fluid tank. FInally, try jumping or bypassing the fuel pump relay to test if have pressure, if this work, then go to the next device, fuel filter, then next at fuel pressure regulator and this way so on.

Keep us updated.

I just had a fuel pump and filter put on my 1993 ford exployer and the cadaylitic converters cleaned out but my engine light keeps coming on after it lurches for a moment around 60 miles per hour.

You cannot take apart the catalytic converters to clean them. They are sealed. If this was a shop that charged you for this service then find an honest competent shop to diagnose the Explorer. This almost sounds like an electrical issue (like arcing spark plug wires). If you open the hood in a really dark area, lightly spray some mist water onto the top of the engine while it's running and see small arcing sparks then it's time for new spark plug wires. You can do this little test for free before you take it to a shop.

1993 Ford escort wagon replaced fuel pump but still cannot get car to start. turns over, runs as long as you pour gas into carburatorl

the fuel filter may be clogged, and not letting fuel through, if not that check the fuel pressure regulator.when vehicle is turned off, you get a delay in building up sufficiant fuel pressure the next time you try to start it. check fuel filter first. then go from there.

1993 ford escort wagon,no electric to injectors

The fuel delivery system uses an electric fuel pump to provide high-pressure fuel to the fuel injectors. The fuel pump is located at the rear of the vehicle, mounted in the fuel tank. It can be accessed by removing the rear seat.

The fuel tubes leading from the fuel tank to the engine are under pressure during vehicle operation. When the engine is turned OFF, the fuel in the fuel tubes remains pressurized for long periods of time to provide quick start-ups. Fuel not used by the fuel injectors during operation is routed back to the fuel tank through the fuel return tube.

The fuel handling components are protected by three fuel filters. A replaceable in-line fuel filter is located inside the engine compartment between the fuel tank and fuel injection supply manifold. A serviceable filter screen is located inside the fuel tank at the fuel pump inlet. A non-serviceable filter screen is incorporated into each fuel injector.

I can get you trouble shooting tips if you want them.

Need the location of the fuel filter on a 1997 Ford Exployer AWD

The fule filter is up inside the frame on the drivers side. You will need to get special tools to get it off. Since it is a high pressure system you CANNOT cut it out and replace it. Must get the special tools.

No horsepower

Check your fuel pressure as the fuel pump may be failing. It should have 60-66 psi at the test valve when you switch the ignition on without cranking the engine (as the fuel pump makes the humming noise)
