I need some advice on where to start with this issue. I drove my 87 GN a few days ago and it ran perfectly. No knock, nothing. Just Buick perfection. That night I went outside and heard a loud buzz click coming from the car. Turns out the power antennae was making noise. I have owned these cars...

Weird. I was driving my 87 GN down a smooth road at about 30 mph when the rear window just shattered. No sign of foul play. There's no rust and I have the extra bracing and bushings. Tires are brand new and I was thinking how smooth they ride when it happened. So apparently no one makes these...

I need some new bushings for my hrpartsnstuff lower control arms. Does anyone know if they are still in business? Their site looks old. If not does anyone know where I can get bushings that fit? Thanks

My 87 GN started showing fuel pressure dropping with the engine running so I put in a new pump. When I first start the car the pressure is low, just like the old pump. So I put in a new filter, didn't help. Put in a new hotwire kit, still didn't help. Rebuilt regulator, but still having issues...

I replaced my fuel filter over the weekend and noticed that the fuel line on the exit side of the filter had a really bad, worn looking, orange gasket on the end that connects to the filter. It was barely on there. I wasn't even sure it was an o ring gasket but I think it is. I went ahead...

Is anyone making wiper arms for our Buicks anymore? I need a new passenger side, but could not locate one at the usual parts stores. Guy at the counter said the black GN parts were no longer available. Did see one on ebay for big bucks, but not going that route yet. What are you guys doing now?

What happened to all the chrome/polished turbo shields? I tried to order from two places and apparently there is a shortage. Someone said the manufacturer quit making them. If so is anyone else making any?

My scanmaster readout has been going out after starting the car and driving around for about 5 minutes, sometimes less, sometimes more. When I shut off the car and then restart it the scanmaster starts working again. I've had it for about 11 years. I can't find any obvious problem with it. Wires...

I had two problems develop today while getting my kids from school. First was when I started my GN the Caspers audible knock detector came on and stayed on until I turned off the car. When I restarted the car the detector did not go off again. This happened for the first time last week. Same...

I just installed an alky system and found that there is very little room under the dash due to what I think is a stock factory "Goodwrench" security system. The box is black and about 6"x 4". There is also a slightly smaller control box mounted beside it. I want to clean up the area, but am a...

Well its 10 pm and I'm in the garage trying to hook up an alky kit I got from Razor. Heres my questions: I have an aftermarket gnx type gauge set, it has VDO gauges. I looked at the MAP that is installed on the passenger fender. It looks like the new 3 bar MAP I bought with the kit. The plug...

I've been trying to remove the crank sensor and bracket for a few hours and could use some help. I took off the 13 mm stud and 13mm bolt, and loosened the pinch bolt, but they are both still very attached to the engine. What am I missing? It appears that the bracket is possibly broken near the...

My 3 hose turbo wastegate actuator line has cracks all over it so I wanted to replace it. Unfortunately they seem to be discontinued. Whats every body doing these days to replace those? Do I need to find a new boost controller? I guess in a pinch I could just try and locate some new proper...

My 87 GN would not start a few days ago. Battery appeared to be dead and would not charge over 60%. It was 3 years old so I just purchased a new battery. I do not drive the car often and it can sit for months in the garage. After changing the battery, the engine still would not turn over...

I am in need of some assistance with a purchase I made. It was a Walbro 340fuel pump, hot wire kit, and ground kit. The problem, as I have already explained on the RACETRONIX tech forum, is that the fuel pump is defective. I need to exchange it. I feel like I am getting the cold shoulder...

Still trying to track down a no fuel problem with my 87 GN. What color is the wiring connector on the center relay on the passenger side of the engine? Mine is black. The most forward relay connector is grey. Is this correct? The center is the fuel pump relay(one with black connector)...

Hey gang I need some help. It's late and I just finished putting a Racetronix G77 plus fuel system on my 87 GN. It included a new 340m fuel pump, new hot wire kit, and new battery ground upgrade. I've been working on this slowly for a few weeks when I've had time (new baby and all)...

Hi everyone, been a while since I have been back on the board. I need some advice/help. I have an 87 GN. I purchased a walbro 340 pump and hot wire kit from racetronix about 6 months ago. While putting the pump in I noticed that the instruction sheet seemed... well... "odd". It was confusing...

Hello everyone. I need some help. I have noticed that the fuel pressure gauge on my 87 GN has been showing a lower and lower pressure for the last few weeks. When I first start up it has went from 38 to 27 now.:confused: This has been over a several weeks period. How do I diagnose what the...

Ok I found another problem while doing spring cleaning. My wastegate hoses and solenoid filter were FULL of oil. I need to replace them. Kirbans has the hoses. But it appears that the wastegate solenoids are now on the endangered list. I think they use to be relatively inexpensive. Anyone...
