I wondered if there had been any new news.



Well, the car is still on jack stands for reason mentioned. I do have 2 issues;
1- When the car starts it idles pretty high but seems to tame when it warms up. I forget if this is normal for a V6? I know my tach is waaaay off. It sounds like it settles to about 900 after about 3 minutes.
2- All of a sudden I lost the highest fan speed on everything climate controlled. Just gone. Nothing.
Thats where at. A big mega storm aimed at us for a couple days so I cant work on it.

Ok so Update:
Its been 2 weeks about since the new fuel pump has been installed. Car has been started several times and reaches a high idle in the very 2000s RPMS. After about 3 minutes it seems to settle at 1000. (Thats my guess as the tach calibration is off).

Well now since the weather is colder (40sF) its taking 3-4 attempts to start the car. Today the car started on 4th attempt, ran to high idle, faltered to a unstable lower idle and died. Four tries yeilded the same result. Starts, high idle, erratic idle and dies in all of about 20 seconds.

WTF?

Im back to the beginning!!!!

Have someone watch the pressure guage when you start it and try to keep it running.

Update Nov. 11th.
We've replaced the fuel PUMP AGAIN with an AC DELCO. Car starts right up and idles lower and smoother. Drove it little and seems to finally run well. I hope this is the winner. Tired of dropping the tank. Thanks to all that helped.

So my car had the exact same symptoms after I installed new/cleaned injectors.
The issue was I had forgot to connect the vacuum tubes to the MAP sensor. One is directly under the MAP sensor and the other goes into the side of the upper intake plenum so check them.

Third fuel pump fixed the problem. Thanks.
