CRAP! GP dash lite woes...
I just replaced all 5 glow plugs about 6 - 8 weeks ago. Everything's been working great UNTIL this past week! It's been a bit nippy here in SW Ohio. The car is always garaged in my attached garage so it never gets terribly cold in there. Anyway, when I go to start it up first thing in the morning I can not get the GP dash lite to glow! But the crazy things works fine the rest of the day!
What's up with that?

It could still be the glow plug relay or relay fuse. You also need to use the correct type of glow plugs and ream the carbon deposits from the glow plug ports before reinstalling.

Can someone explain how NOT reaming can cause the problem I'm now having? Thanks...

I don't think it is a reaming or not reaming problem. It sounds electrical to me. I would check your relay and fuse. If that doesn't help, check to see if the instrument cluster is grounding properly. If it's not grounded the GP light won't come on.
I just went through this. The light wouldn't come on, but the plugs where glowing. I found I had a bad ground to the instrument cluster and that fixed the problem. I had burned one of the circuits on the rpm, oil, and fuel gauge.

First of all, are the GP's Bosch or the cheap crappy autolights? If the autolights, you probably have a bad one (or two). The heat from starting the car "fixes" the GP for the rest of the day. (Or atleast several hours) One way to fix the problem is to start the car every few hours thoughout tht night, but that fix isn't very fun to live with,,, in the middle of winter in Ohio.

The car is always garaged so moisture shouldn't play a roll here? I bought BOSCH GP's for the car. I have a little spare time this evening so I may actually get to do some troubleshooting!
Where is the grounding for the instrument cluster? Do I need to pull the cluster? Thanks for the help

Update!
Well I think I have solved this 'mystery'!
I replaced the short fuel return line that has the plug in it b/c I noticed it was wet and the fuel had actually ran down into the area of the GP. So far, so good! It all dried out and seems to have cured the problem. KMFC! (keeping my fingers crossed!) PS: I went to the dealer to buy the plugged end piece of fuel return line but after hearing the price I decided to make one since I had plenty of new return line available. I was there to buy a valve cover oil filler cap. He had already quoted me $5.xx for it but when I added the return line end my invoice was going to be something like $13 or $16 ! Said "Thanks, but no thanks!"

Plugged end piece line...you mean they actually sell that line assembled as a part?
I just got some regular 1/8 fuel line, replumbed my returns, took a razor knife and shaved the old hose off of the little metal plug, and stuffed it into the new hose, its just an arrow shaped metal pin. Hasn't leaked a drop yet. |
