Sweet!

@  dezldave961 : (07 May 2020 - 04:14 PM)

Got bored and started making build video...

@  dezldave961 : (04 May 2020 - 04:05 AM)

I need to hunt down the little black trim bar that's at the top edge of the GS rocker panel cover, for driver's side between rear door and wheel well.

@  ejguillot : (03 May 2020 - 02:42 AM)

I've been on there too. I hope this forum is kept open, there's too much info to allow it to be lost!

@  dezldave961 : (24 April 2020 - 10:25 PM)

I've been monitoring GrandPrixForums and 3800Pro (don't have FB)... also hopped on TurboBuick, but 99% GN chatter from boomers

@  ejguillot : (19 April 2020 - 02:33 PM)

Everyone at home, plenty of free time.

@  ejguillot : (19 April 2020 - 02:33 PM)

Nobody posting? Why not?

@  ejguillot : (27 March 2020 - 05:19 PM)

Congrats on the Comp G GTP!

@  crossout : (25 March 2020 - 05:49 PM)

Wow this thing has died off I just myself 05 Comp G 3 weeks ago way different than my 2000 regal gs that I had it rusted out to hell strunt towers. :D :D

@  dezldave961 : (20 March 2020 - 04:18 PM)

Pulled turbo engine, prepping MP112 setup... also doing some work-from-home stuff

@  tpivette : (19 March 2020 - 08:57 PM)

So far so good. Still working, fortunately.

@  ejguillot : (16 March 2020 - 03:46 PM)

how's everyone doing? With coronavirus and all that?

@  tpivette : (25 February 2020 - 02:35 AM)

Just got my GS back on the road. Wife is pressuring me to sell it... don't know if I want to or not

@  monte0 : (17 February 2020 - 05:04 AM)

Popped on to see how things are. Been a couple years...

@  ejguillot : (14 January 2020 - 10:36 PM)

Hope the new year is treating everyone well..

@  ejguillot : (16 December 2019 - 01:55 AM)

Hi all. Decade is coming to a close... I'm feeling a little old!

@  M_Dogg : (05 December 2019 - 11:20 PM)

Cheers!

@  ejguillot : (02 December 2019 - 01:13 AM)

Hi there. Some of us are working to keep these cars alive and running. Glad you had a good 15 year run.

@  opera_bob : (30 November 2019 - 08:39 AM)

Every time I see an Old Buick I have major respect for it. I know what kind of torque these cars make.

@  opera_bob : (30 November 2019 - 08:38 AM)

I sold my 2002 GS back in 2017. She was falling apart all over the place. So I sold her and bought a 2017 Focus RS in 2017.

Cars been running fine and starting normal after swapping fuel injectors. Lately however it hasn’t been starting. Thought it was the starter, swapped that out but it’s still doing the same thing.

I’m thinking it’s the ignition switch because the key inserts and turns fine, everything powers up when I go to start, there’s a click, and then nothing. If I wait a few minutes, some times a half hour, it starts just fine. Sometimes if I turn the key all way to the on position and then off 3-4 times, it’ll start up. Others, I have to wait

Does this sound like an ignition switch, a 2nd bad starter, or maybe an electrical issue killing my starters?

Thanks

Your battery has been tested to be good? All cables and connections are good, clean, and tight? To me your description sounds like a bad battery or bad connection.

I’ll have it tested and recheck connections but I tried jumping it once thinking that was it and it still wouldn’t start

If you have bad connections like OhMyGS said then it may not jump start. Did you get it checked out?

As said by OhMyGS and Fast86GN, you'll want to verify that the wiring and connections are working as expected. 

 

As these cars age, I find the wiring does need some attention and remediation to prevent problems (replacing the black harness sleeves is a common thing, after 20 years of heat soaking the plastic crumbles like old crackers).

Car was running fine for a while, issue popped back up. Had the battery tested, all is well. The connections are clean and corrosion free. I swapped a few relays in the fuse box, the 3604’s, from the cooling fan slots to the ignition main and crank. The car started. Then I shut the car off, and it wouldn’t start. I’m having trouble believing the new starter is bad

Just for shits and giggles, get yourself a piece of 8 or 10 gauge wire. Connect the new wire between the negative battery post and the dogbone mount on the engine. See if that helps; at least it's cheap and easy.

You think it’s a ground issue? I was also gonna take some jumper cables and connect the positive to the starter solenoid to see if it’ll crank

You can certainly do that.  It would be easier (and a better test) to connect the positive battery terminal to the solenoid terminal that engages the solenoid.

 

Regarding engine grounds, there is (or should be) a fairly substantial ground cable bolted from the negative battery terminal to the engine/trans bellhousing bolt nearest the starter.  There is also a smaller diameter ground cable from the negative terminal to the chassis (less than a foot run, ends more or less underneath the under hood fuse block).  The chassis connection for that cable on my Regal wasn't that good - I made and ran a cable from the negative terminal to the bolt on the chassis brace that runs over the battery.

 

Test the ground cable and positive cable (from battery to starter) this way (straight out of the FSM):

 

Measurements are engine off, all cables attached as normal.

Positive cable: With a meter, first measure the voltage between negative and positive terminals.  Then measure from negative terminal to the starter solenoid terminal that the positive cable attaches to.  The difference in the measurements should be less than 0.4 volts.

Ground cable: With a meter, first measure the voltage between negative and positive terminals.  Then measure from positive terminal to the engine block, then to a bare chassis point.  The difference in the measurements should be less than 0.4 volts.

 

Try that and let us know the result.

Everything you just said is incredibly useful, thank you. Will run through all of this soon and report back.

Finally got around to it; bolt for the ground wire off the negative terminal was rusted to hell, it snapped when trying to take it off. Got a self tapping screw, sanded next to the old bolt and attached the ground to the chassis, slapped some dielectric on it.

Seems to be starting now, but it still occasionally does the thing where it clicks once and then doesn’t turn over

The one that ended underneath the fuse block?  That's the one that I found lacking.  Definitely consider running an additional ground from the chassis to the negative battery post.

Yeah the short one beneath the fuse block. I’ll try running an additional ground

Been traveling for work a lot, haven’t driven the car much but when I do it’s been starting fine. Had to contend with the coolant elbows, there were leaking and I didn’t realize. Did a flush and swapped elbows.

I got a new ground wire all made up, just gotta slap it in there
