Injector circuit malfunction

[sgo70]

Thats what the car reader told me??? As well as cylinder 4 misfire???
Are these related to an O2 sensor. Looked it up in the Haynes manuel and didn't find the " how-to " fix I was lookin' for. :shock:
Any input would be great.
Thanks.

Read through the trouble shooting section on how to test injectors.

Involes testing the voltage being supplied to the injector itself.

From there you will be able to whittle it down to wiring or the injector itself.

My bet is that its a bad injector, but you will have to test it all out to be sure.

sounds hard, I'll be back in three days :shock: .

Not at all. You just hook up a  tester to the wires that go to the injector. Turn it over and take the readings.

The haynes manual will have numbers that are in spec. Just carry on from there.

You have a misfire code because of the injector code. Meaning the injector is not working.

Unless you have physically damage the connection at one time or another, the more common problem is a bad injector, and they are not hard to change.

You can do it the long way.

Switch two injectors around

Hard reset computer

Search for codes again

Same codes same cylinder = bad connector

Same codes, switched cyclinder = bad injector

But the haynes trouble shooting should get you the same answer without the switching stuff around.

O.k. I finally got off my arse and took a shot at this, I pulled the injectors off and swapped the suspect one over to another cylinder. I started it up and it ran few a minute or so until the number six started leaking fuel. After deciding I can't push it far enough away from my garage to just let it burn, I shut it down. When I pulled the injector out I noticed I sliced an o-ring. This is really getting fun!!! So now does anyone know where to get an o-ring kit? I couldn't find anyone with a new inj. in stock either. HELP! :x  :x  :x
SGO.

Just go to Napa and get an injector o-ring. Almost all makes of cars and injectors all use the same o-ring, which will work on yours. Also grease the o-ring on the injector and the hole you slide the injector into so it will slide in easy.

ok I just found the most outrageously priced item in the world!
Had a hard time finding the new o-rings so I went to the dealer near my house. I called ahead and he said he had a kit for $25, so I go down and of course it wasn't there, so the guy searched around and found another one that should fit. Now I don't blame the guy for anything, he was quite helpful, so he brings me this "kit". It consists of, get this, ONE O-RING for $25.00!!! So I took it, right in the you know what, no grease or warning! :x  :x I'll be a little more careful putting these in I guess.

Weel I swapped injectors and the problem showed up on number 1 now. Pretty sure a new injector is required, thanks for your help.
