If it's not the fuel filter it could be the EGR Valve( Exhaust Fuel recirculation ).

Check your fuel filter. If it is clogged the system will still create pressure but no fuel will get through. Hope this helps!

1991 ford tempo ran fine went to store it started fine and then just died


Likely a gas or spark problem. Spray starting fluid into the air intake while cranking it. If it then runs for a few seconds, it's a fuel problem-maybe the fuel pump, filter, or injector circuit. Check if gas is getting up to the engine.
Buy an inexpensive "spark tester" at a parts store, and check for spark- if no spark, the ignition circuit will need diagnosed- could be the ignition coil, maybe the electronic ignition module-several possibi9lities. Let me know what you find, or if other questions..

Car was running fine,went to store,come out turn the key,plenty of crank,but just wont fire,whats my next step?


Determine if it is an ignition or gas failure. Does the fuel pump still work? Do you have gas up to the engine? Watch the injectors for spraying a cone pattern of fuel when car is cranking-that is, if the car is throttle body injected. If multi-port injected, you cant see the injector spray, so check for fuel at the engine fuel rail, or crack the fuel line at the engine to see if fuel is under pressure. The correct way is to check fuel pressure with a gauge, barring that, see if fuel is getting to the engine. If not, pump may have quit.
To check ignition, pull off a plug wire and check for spark when cranking. Be careful of shocks, hold wire with a glove or heavy rag, push the rubber boot back to expose the metal end of plug wire, and hold the wire 1/4 inch from a metal piece on the engine. Have a helper crank the car over and observe spark jumping from wire to ground-a good spark is a blue, snapping spark. Good ignition. A weak, inconsistent, or orange spark is a sign of ignition problem, possibly a bad coil, bad ignition module (the TFI module), or other ignition component.
If you have good spark (good ignition), and still unsure of fuel, spray some starting fluid or carburetor cleaner into the air intake and crank the car over. If it runs for a few seconds and dies, you know gas is the problem. The pump has quit or the fuel filter is clogged. You may even want to try this first, cause if it tries to run, you know ignition is good, and gas is not getting to the engine. Good luck.

1985 ford f150 300 6 cylinder with electronic ignition has spark to all 6 and fuel but won't start. All fuses are good and firing order is correct.


Get a testing light and connect it to the injector wires. You can have fuel pressure, but if the injectors do not open, it will not get fuel.

Test with starting fluid to see if fuel is the problem. If you have spark and no response after adding the starting fluid, its something else. Since the timing chain has nothing to do with the crankshaft sensor sending a signal as the crankshaft turns, the top half of the engine may not be turning to move the valves. Look in any breather holes in the valve cover to see if the tappets are moving.

Please rate my info.

1989 ford stalls when idling ,runs rough at idle


Check for any trouble codes in the engine computer, and have the fuel pressure tested. If it is throttle body injection. observe the spray pattern of the injector when it pulses. You should see a cone pattern of the fuel spraying down into the intake. If it drips, or appears anemic, the injector might be partially clogged. Try some injector cleaner in the gas tank.

It could be a fuel supply problem, plugged fuel filter or faulty fuel pressure regulator. When you turn the key to the on position, you should hear the the fuel pump run for a couple of seconds. This will tell you that the fuel pump is getting power, but it could still be weak. There are other things that could be causing the problem, does the engine have spark after it stalls?Do the injectors function?What is missing from the equation? Engines require compression, fuel, spark and air to run. If it is a fuel supply issue, after it stalls, you should be able to spray carb cleaner (acts as fuel) into the throttle body to restart the engine and keep it running at an idle by feeding the right amount of carb spray.
