Have you checked fuel pressure?

Not built in, but if it was there and not torn up then it's all good. |

The device you are using to check the codes, can it also read live data? Like coolant temps, open and closed loop? |

You can check the timing but it is not adjustable. |

Ok, new development. It appears that the number 1 spark plug is not firing. Or rather, there's no power between the coil (on top of the number 4 plug) and the number 1 plug. The wire is good, so I thought perhaps it was the ignition coil. Picked-up a new one and popped it in, and still no power between the coil and the number 1 spark plug. Tried swapping the coils, and same thing. There seems to be an issue somewhere down the line from the number 4 spark plug. Does anyone know where to find a pin out diagram of the ignition coils? (1st & 4th cylinders) The diagram in My Haynes book is not very specific. Looking for the correct voltages. |

I can try and look it up after I get home. |

I thought the 2 coils on a 4 cylinder Metro were on #1 and #3? Oops. Never mind ![]() Edited by suzukitom, Sep 30 2017, 11:15 PM.

You might find it useful to check this test from the site where the picture above was from. http://easyautodiagnostics.com/suzuki/1.3L/ignition-coil-tests-1 |

Looks like suzuki toms link is correct. ![]() Edited by freegeo, Oct 1 2017, 12:04 AM.

If you are having ignition problems, or poor spark. That could be the reason for the O2 sensor code. Staying rich due to unburnt gas. |

After checking with an inline spark tester, there is an initial spark that goes through when I first start it, but then nothing. As if the coil stops getting power after ignition. Looks like neither the #1 nor #4 are getting any power after ignition. Perhaps the Power Control Module is no bueno?

I would start with removing the oil pan gasket and use rtv only. |

Just another question...did any of the teeth get broken on the crank gear?... good one... ![]() bad one... ![]() |

With out knowing if the pcm is seeing a good signal from the crank position sensor, I would not bet on the pcm being bad. The signal from the ckp sensor is what the pcm uses for fuel and spark control.

Oh my gosh. Just checked it again. It is a little beat up. There's a tooth missing, and one is a little bent. I would assume that the gear from a 3 cylinder model is not the same? |
