OK... I don't know if I am holdig good fuel pressure right now. I am going to take a gauge over to work and throw it on to see what I am getting. I just have a bad feeling my regulator may be bleeding down very quickly. Why would it go bad so quickly?? I did have the fuel rails tipped in that direction and I was wondering if maybe some rust or other sediment has blocked it partially open.

On my way there in the Z right now to see if this is the problem.

God, I hope that'* it. You have a spare fuel rail, right? I actually posted some other ideas earlier, and they didn't post! Make sure you check the vacuum line that controls the Boost Solonoid. It'* prone to getting VERY brittle and cracking. Mine did this less than 2 weeks ago. Keep us posted, I'm really interested in this one!

OK. I just checked the fuel pressure and it is just fine. When I replaced the supercharger last night, I also replaced all soft lines and replace the one to the boost control solenoid with a brand new one (habit I picked up when I had my Typhoon) so there are no leaks anywhere.

Will this pulley have anything to do with the car not running right?? Common sense would tell me that with the larger pulley it is turning slower (obviously) which would also cause the engine to receive less intake air. Then again, when it died last night, my buddy saw a small puff of smoke from the back of the engine which I am guessing is just a leaky exhaust manifold. We swapped 2 coil packs with some a friend had and it seemed to start but run very badly like it was just way rich or weak on spark.

I am stumped on this one.

Ok, I'm stumped too. What year and model did this 'new' SC come out of? Tell me it'* an M62 from 92-95, not an M90 from 96 and up. The larger pulley is really perplexing. With the M62 and the RPMs it runs at, a small change in pulley diameter makes a HUGE difference in how it runs. You may have something there, but if it came out of an older Bonneville, I don't understand the pulley diameter, unless your original had the smaller pulley to begin with. I remember reading that your wife'* Bonneville is running the smaller one (and only one is available for the Bon) so you probably know what size that is!

The supercharger is BRAND NEW. It was never installed on the car. The guy bought it then wrecked the car and sold it to the salvage. It is the correct style as it has all the correct connections and is identical. The only thing I noticed different was the bolt pad to the rear of the throttle body was about 1" shorter necessitating the use of an equally shorter bolt.

I don't know. I am wondering if the car started up then actually flooded itself out due to insufficent airflow into the engine. I guess I can change the pulley out and see what happens but I just don't see how it could make it be like this.

My car is a 92.

You're kidding me! Why doesn't my manual spec that code???????

That'* why the damn car won't start! It'* VATS!

I'll be a sunovabitch. Thanks a TON, Jr.

You had a Typhoon, what happened to it?

According to the 93 manual, if you have Code 58 stored, the vehicle will still run. Once you clear it, though, it will not run anymore.

It can be caused by a loose ground or poor ignition or battery connection. The fuel enable signal from the PASS Key module is not getting to the PCM.

OK. I swapped to the pulley that was originally on the car. The car started but blew a bunch of what I think may have been antifreeze out of the exhaust. It eventually cleared out and the car idled. I let it sit and tried to restart and nothing. I have not cleared the codes and I am still seeing a code 58. I get no security light as if it is VATS. The other meaning for code 58 is no crank signal.... Is there a wiring harness somewhere that may be coming unplugged? I checked the one by the balancer and it is in tight.

Getting ready to go put a timing light on it to see if it is firing.

Anyone need a cheap Bonneville with a brand new supercharger??

My Typhoon got totaled. You can see it on my site under wrecks. 17,000 in damage, the trans broken in half, roof buckled, turbo broken off of engine, and more happened. http://www.aldersgarage.20m.com

The light does not stay on constantly on the VATS. It works properly. Besides, if it was just the VATS, why would it start at all? It is starting and running very rough sometimes, or not starting at all. If VATS activates, the car will start, die, then the security light will come on solid for about 5 minutes. I have 2 Z28s also and have had friends with Camaros have their VATS go caput. It is definitely not a VATS problem.

If you go to a generic code manual, code 58 can also be no crank signal.
