Seems like no fuel reaching motor, possible block in fuel filter?

You'll have to do a fuel pressure test to determine if the pump is reaching the required fuel pressure. Running pump dry can destroy it

Fuel pump failure or blocked filter.

If you are positive it is the fuel not reaching the engine, replace the fuel filter. Next after doing a quick Google search on your model, it seems the fuel pump relay can be an issue with this model. Have the relay tested or depending on cost, replaced.

Blue smoke is oil. Compression check. and check plugs for fouling.

There are multiple answers for the vague description given. A dirty, or Wet Air Filter could cause this. Did it occur suddenly, after possibly going over some road trash/debris. That could block air intake to the Air Filter. Jumping at idle, is it with the A/C on, or it off. When the A/C is on, it is supposed to trigger the cold start, additonal fuel source on the fuel rail, to increase RPM's to compensate, for the A/C drain on the motor's power. If a small 4 cylinder engine, it can be a randomly misfiring plug, or plug wire. What does your owner's manual, recommend as time interval to replace plugs & wires.????? Have you followed that maintenance schedule???

Check/Change the fuel filter. A dirty fuel filter may be blocking fuel from reaching the engine.

It's possible that you have an air bubble in the fuel line. This blocks fuel from reaching the engine. To clear it, you will have to bleed the line at the fuel filter.

The other possibility is that the fuel pump is not working. Turn the ignition key to the on position. You should be able to hear the fuel pump humming. If not, check the fuel pump fuse, in the fusebox under the hood. If the fuse is ok, you will need to trouble-shoot the pump.

ok could be a few things.

Have you changed the inline fuel filter? these usually have paper filter elements and after a while can be clogged with moisture which blocks fuel flow. The fuel pump will still have good pressure but the fuel rail will lack the flow required and you may burn out an injector as its running too lean. Secondly, the MAF sensor, could be dirty, clean it with electrical cleaner.

I think its more likeylt the fuel filter blocked. Try and bypass it if possible, reset the ECU and try agiain

check volts at pump with test light, replace pump

Either the fuel filter is plugged, or the fuel pump is worn out. There is also a sock-filter inside the tank that can get plugged. Are there there mal-functions indicated by the check engine light? Read with a rented scanner and pursue any recognized faults.
