How to check the injector whether it supplies fuel on plug number one of my 2.6 microbus cylinder head


one cheap to test the injector or the wires and controls is to exchange no 1 injector with an injector from another cylinder
if the problem moves to that cylinder --get a new injector
if it stays with no 1 cylinder - it can be wiring, connections or ECM

#1 cylinder is not firing. Coil is working as I switched it with another cylinder. Fuel injector is new. Mice chewed the two injector wires at the clip to the injector. They were pressed together. Can


Have you tried replacing the plug on that cylinder ? Might be bad . Also I would replace the wire to the injector that the mice ate. Could be damaged in more then one place.

Fuel injector diagram


old post
no engine stated, ?? which one? 4AFE or 7Afe (TOY ENGINE)
the harness will not allow cross wiring injectors
how did you do that?
the #1 injector is on #1 cylinder
and on #1 fuel rail port.
the #1 cylinder on inline engines, the crank pulley end.
if you need wire colors, we can do that too.
or log in to mitchells DIY and read. that.
here is the 7aFE wires
B-O is 12vdc power key on, the ECU fires the 4 on right.

Car idles rough, sometimes dies in reverse, it's worse in cold.


A cylinder that doesn't fire could be 1 of 3 things: no spark, no gas, or no compression.
Sure, it could be a bad injector, or clogged, but you should do some tests before buying an expensive new injector. You should first check the injector circuit on #2 cylinder. It's a pretty simple circuit, really. Each injector has 2 wires, a power wire and a ground wire. The power wire is one wire, which is spliced to each injector, and has battery voltage on it anytime the ignition switch is on or in "run". Each injector's ground wire is a separate wire going into the computer. When the computer internally grounds for a split second that injector's circuit, the injector sprays fuel out a tiny opening, a nozzle. You can check the circuit for #2, both the power wire and the ground side of the circuit with a test light. Post back and ask, if you want me to explain.
You also might want to check the compression in #2, just to assure you there is no mechanical problem causing a loss of compression in that cylinder.

Misfire from cylinder 1 and fuel injection stuck open


One problem will cause another in this case. You can try to just change the fuel injector in the number 1 cylinder and see if the misfire straightens out.

You can use a test light to see if there is a pulse in the wire harness to the number 1 injector. Or there are plug-in lights which attach to the head of the injector harness to show firing of the injectors. Either way, th pulse should be a timed intermittent burst to that 1 cylinder when it is time to fire, just a spark goes to a sparkplug in intermittent bursts.

The crankshaft or camshaft sensor should send divided, pulsed signals to open the injector for fuel release. If the injector is jammed so that it does not go back to its seated position, you will get excessive fuel inside the engine when it is off. The fuel will bleed down into the crankcase and dilute the oil over time. This ruins an engine.

The fuel system normally remains pressurized and when the engine is turned off; the fuel will leak into the cylinder that is not shut. You may have to change the sparkplug as it can be gas-fouled by now. An oil change would be a good idea after you change the injector.

2003 Hyundai Sonata with 4 cyl. PO301 error code. Have replaced spark plugs, wires, coil packs, and mass air flow sensor. Replaced air filter due to heavy gas smell. Car was starting after tapping gas 3...


P0301 - Cylinder 1 Misfire Detected.

Possible Causes:
- Improper spark plug at cylinder #1
- Insufficient compression at cylinder #1
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #1
- Fuel injector #1 may be faulty
- Intake air leak at cylinder

Possible Solutions:
- Perform Injector Service
- Replaced Spark Plug #1
- Replaced Injector #1
- Replaced Ignition Coil #1

Being you have a heavy gas smell I would look into the injectors. If injector #1 is over producing it can cause a misfire. Test your compression and fuel pressure.
