Just a follow-up..
I replaced the fuel pump with a Delphi unit from RA. Works great now.
Dropping the tank was not as hard as I thought it would be. The hardest part is removing the rubber fuel fill hose and vent hose as the tank is being lowered.
Also there is a rear brake line blocked by the tank ...

Try bypassing the fuel pump relay at the fuse/relay center under the RH dash. The wiring diagram is here: everything-electrical-and-electronic/topic48336.html

Thank you, this helped. The relay was clicking, proper power.
At the fuel pump connector by the tank, I got power at the grey wire for 2 ...

Hi,
My 1999 SSEi failed to start today after sitting a few weeks and it seems its the fuel pump. Spraying a bit of gas in the intake gets the car to start for a second or two, so ignition is working.
I removed the fuel filter and turned the key to run, and nothing comes out of the fuel line. I cant ...

Fluid level was good, but color is dark red.
Transmission shop technician took it for a road test and said the clutch material is probably worn out.
Rebuild & labor is $3000+ ($CAD or about $2200 USD)

Sigh... yet another issue on the 99 ssei :sad:
The transmission started doing this today:

"No Forward Cold, Neutrals at stops, Shudders on take off"

I remember when the car was a few years old it did this, and the solenoid valve(s) were ...

Howdy.

Did you ever find out what the issue was? Mine's doing the same thing and I've replaced every vacuum line and sensor in this sucker.

Thanks.

Haven't had too much time between all the rain here..

resistances in the wires and coils were pretty normal.

hi, since you have already done ...

Hi thanks for all the great info.

The stumbling problem started after I replaced the spark plugs (about 6 months after). But the wires were replaced after the problem, but did not solve the problem.
But I replaced the fuel filter just now... no difference.
I checked the coils.. all were about 6k ...

Hi.

My 99 SSEi is running poorly these days. It stumbles under load (climbing hills, accelerating).
Or if I rev past 3000 rpm when parked - very fast vroom, stumble, vroom, stumble.
I also got the P0442 code pop up recently (I've have not had any other codes for years)

The car has new spark plug ...

Ok, here are some photos and a video:

Watch Video of Trunk opening

I'm not sure what the gas shock specs are, I can try and look it up for you but ...

One thing I like about my 99 ssei were the nice glass headlight lenses. Well the other day I got a rock through my passenger side headlight lens. I'll be going to the salvage yard get another lens. What other models and years use the same lens? (eg: does pontiac transport use same headlight ...

I cant remove the bulb from the high-mount brake light socket in a 1999 ssei. Removed the socket from the trunk and detached the socket from the wiring, then I tried pushing in the bulb and turning it, but it wont budge.

Do I have to replace the whole socket/bulb as an assembly since the socket ...

I noticed after I replaced my shorted out evap solenoid with a new one, the radio now keeps the correct time, no matter how long the car has been parked!! weird.
Before it would lose about an hour a day. I think the shorted evap solenoid sucked power continuously.

Hi I thought I'd update this. Instead of welding or getting new torsion bar springs, I hooked up two gas shocks and works great. Lifts the trunk lid in the air when I hit the trunk button. The shocks are fairly well concealed. One end of each gas shock connects to the hole on the trunk lid arm where ...

Hi, one of my 99 ssei trunk spring torsion bars broke.
How expensive are these things at the dealer? or are there other brands?
If I go to the wrecker, what other models & years have the same one as the bonneville?

thanks

So I took the evap purge solenoid out and tested it. It was bad. The way I could tell was that I could blow a bit of air through it and when checking the resistance on the solenoid terminals it appeared to be shorted out. I put a new one in.

For that U-shaped tube, I got a piece of vacuum tube and ...

I keep getting this code when I start the car after it is parked on a hot day. Purchased a new fuel cap, cleaned the surfaces and cleared the code with the scan tool. Code came back.

Problem is I need to pass emissions test next month.

I want to check the evap canister, solenoid and the lines ...

My 99 ssei suspension is still the stock original. There's about 100k miles on them.
During cornering the car will sway and lean pretty badly.

I am going to replace the sway bar links again, since they look worn out and rattle.
If that doesnt fix it (and I dont think it will) how do I tell if its ...

I was following the great write-up about changing the accessory belt but that was for the non-supercharged engine.
There is one tricky piece of the puzzle when working with the supercharged engine, which I learned the hard way.
So I'm just posting this for reference to others (and myself when I have ...

It sounds like a ground buss issue,look here to see where to look http://pontiacbonnevilleclub.com/forum/viewtopic.php?f=19&t=30286
I have heard the headlight switch can also be a problem,mine was,but I have a 93 and some have said the newer switches like yours are better.I would check the ground ...

Hi, I have a 99 ssei with some electrical problems, mostly interior.

2 years ago my battery died and I replaced it with a Deka Intimidator AGM. Everything was working good except the radio kept losing its time.
Now the interior lights (not dash, just all reading lights and interior door lights) are ...
