Do a compression check on #5 cylinder.

Ron M · #3 10-01-2004, 12:26 PM

that was my next step, but thought it might be something more simple, thanks, Ron

Get the actual code for us and not just the mechanics description of it.

If it is a cylinder #5 misfire, chances are you need to change that injector out for one that doesn't have the end poppet valve clogged.

Here is the injector, take about 1 hour to swap out.

If it is that cylinder misfire, first check for spark going to that cylinder by sticking a screwdriver into the plug wire and hold it about 1/4 inch from a ground source and look for spark.

If you have spark, you have no fuel in that cylinder and you just swap out the injector.

thank you I will try that.

Come back here and tell us also.

We need to know when a fix works.

Please don't just ask for help and screw off.

We need feedback.

Ron M · #7 10-02-2004, 06:40 PM

well, I'm not screwing off, I'm on disability and I can't afford to buy a injector yet, and when I do I will be very sure to come back and let you know what happened.

Excellent.

Actually, you could pull one off of a wreck if you want.

Much cheaper.

from what the mechanics are telling me here is that with mine I have to take off the intake manifold to replace it, I have a 2002 S-10 with the vortech V-6, is this right? thanks Ron

BlazerLT · #10 10-12-2004, 02:26 PM

NO, the injector pos is between the intake and the distributor on top of the engine.

I suggest buying a Haynes or Chilton Repair manual for this repair, it is $15 and tell you step by step what to do.

Ron M · #11 10-12-2004, 09:09 PM

ok, thanks a lot, I will go buy one tomorrow.

Ron M · #12 10-13-2004, 10:28 PM

I got the injector today but the books only go up to 2001, will that be the same as my 2002? thanks Ron

BlazerLT · #13 10-13-2004, 11:14 PM

Yip, pretty well exactly the same other than the computer which doesn't affect this repair.

Ron M · #14 10-13-2004, 11:54 PM

thanks I will get one tomorrow, thanks for all your help.

Ron M · #15 11-06-2004, 06:49 AM

I put it in yesterday and it works great, thanks for all of your help,
