TBI Burb dying in gear, My Turn.

also I can't remember but did you say you checked the fuel pump relay?

Just rebuild yours it's wicked easy. Get a new pickup coil and module. Drive the pin out of the drive gear. If you look at the drive gear it has a dot on one side. That dot faces the same direction as the rotor on the pole piece. Take out the pole piece and replace the pick up coil. I usually wire wheel the pole piece and lube it with some engine oil but not too much.

yeah, I know, but I really don't want to, it is an option if I get into the mood to work on it again, figured this would be a good time to upgrade.  I may do that this weekend if I don't break down and get a new one...

have you tried to replace the ignition module with a known good one? I've had similar symptoms with vehicles I'v had in the past that a new ignition module cured.

My only knowm good one is in my DD, and I am definitely not pulling it apart.  With a new distributor, I would eliminate all issues with the distributor in one swing.

also I can't remember but did you say you checked the fuel pump relay?

Yep, checked it.  It is getting plenty of fuel.  It does now have a nice occasional miss to it now.

The reason I say that is the relay can overheat. Take a jumper wire to the fuel pump test lead and bring it B+. that bypasses the relay and runs current directly to the pump. See if it still dies with the jumper wire on there.

  I heard it through the grape vine !!!   Chris is driving the Burb ?
Could it BE !!!!   He has killed the gremlins !

[Captkaos]

Hmmm, that would be me, so you really heard from the grape right? 
I just drove it all over my neighborhood and stopped at every stop sign.  Stayed running the whole time.  I am getting a code 44, but I have an idea where that is coming from.

After swapping the cap rotor and coil, the Burb developed a miss.  I had time today to look at it and pulled the distributor to rebuild it.  Afer getting it out the magnetic pickup was falling apart.  No one had that piece so I got a new distributor.  After getting it in, it is running good again.  Yippie.

In retrospect, I suspect that there was a barage of problems with this.  Short of replacing the MAP sensor, temp sensor and TPS, everything is new.

Pics to follow.

Well this is great news! I s'pose it's too late to make that Maggie Valley thing?  . Now if we can just find you a window..

[Captkaos]

Yeah, just a little late on that trip.  The company I got the window from Friday better get me a new one for free since this one was bullseyed in the corner when I got it...

Next on the list is the rotting tailpipe....

[VileZambonie]

Cheese and Rice. So it was just a bad pick up coil... Well glad you got it straightened out!

[Captkaos]

The last part was the pickup (that is when the miss started), but I believe the bad injector was slowly dying, which was the cause.  I drove it some more today and still holding up fine.
