#139 of 370 Re: 2005 Grand Prix SE - Loose Accerator and Power Steering at Highway Speeds [prochie]
Dec 30, 2008 (9:35 am)
Here is an update of something similar to the symptoms I was receiving. I found a post from another forum that suggests there is a GM TSB 05-06-037 recommending a PCM firmware update (something I initially asked the dealer to look into but was instructed on how to use the cruise control instead) along with the high-resistance from the negative battery cable. Here is the complete posting. My issue is similarly different - that is my engine remains running it doesn't stall.
Owners of 2005 Buick
Allure and LaCrosse
models and 2004-05
Pontiac Grand Prix
models with the 3.8L
engine may experience
engine stall accompanied
by instrument gauges
dropping to zero. The
tachometer may continue
to operate normally at
this time. In addition,
the low fuel indicator
light may come on.
The condition is caused by intermittent high resistance between
the negative battery cable and the right side frame rail. To
repair, remove the cable, clean the surfaces of any corrosion
and apply a coating of dielectric grease. The TSB states that it
is EXTREMELY important that you use a torque wrench when
retightening this cable. The spec is 89-106 INCH lbs.
GM is also recommending a PCM software update. Consult TSB
05-06-037 for details on the software update.

I had a similar problem...I had been doing some work with valve cover gaskets and had to remove the ground wire from the coil pack to the engine block..when I rechecked everything..the ground wire was loose, not visibly but when reconnected and made sure to tighten the nut back down..it started..hope its that simple for you!

I have a 2002 Grand Prix as well. I had the fuel pressure regulator replaced and haven't had any problems since then. My car started this way and unfortunately it lead to it just turning off at random. To have the work completed was 234.00. I hope this helps and saves you money in the long run.

I have had that same exact problem, My car would start, stall then stop at random. I did a complete tune up, everything included. Just recently I replaced the Fuel Pressure Regulator, which is located right in front of the engine. I have not had any problems since it was replaced. My car doesn't stall, stop or turn off any more. It was a total 0f $234 for the parts and labor. Hope this helps.

there's a rev limiter that kicks in right over 4k RPM.
When not in park, you can rev higher (i.e. when driving)

I HAVE A 98 GRAND PRIX GT which has no hazard flash. so i went to the car to find a fix for the lights, and i found 1 fuse in the glove box it turns out to be for the hazards. I put in that fuse and the whole car shuts down. i tried to restart it with the fuse in but no luck. I took out the fuse and left the car to sit for an hour. i came back to restart it and BAM it easily started. I pulled out drive and drove fast up/down street engine sounded great. Pulled back in my drive turned it off, and restarted it 5 times while warm with no trouble. I might buy new relays/battery.

This was copied badly from gmserviceinfo.
Basically the gauges going crazy and stalling can be contributed to battery cables and/or pcm needing update. Good luck. I am going to try it.

Car wont start.
Starter acts fine.
Battery is fine.
Fuel Filter was replaced.
What is the most common cause of this issue?
