Driving it today it was a little less hesitant..i was wonering if it was the fuel system additive working through.

Luckily for you changing a fuel pump on a 2000+ is easy. There'* a access door in the trunk, no need to drop the fuel tank.

lol..your right i have changed the fuel level level switch in past for this car and it was pretty much easy...I had 92 Bonneville and it was hell to change fuel pump!

It'* not that bad in the old body style. Mine'* been out so many times I use velcro to hold the tank in.

back at mechanic'* the worker told me it was at at 51 and 55 reving engine on drive not 35..he tried it again and it reads with key on 50..with engine running idle 45...with me reving engine on drive with brake on it goes to 51..is this good? the alldata is saying it should between 48-55

That'* not to bad. Better then 35. Are you still having problems?

yes.. but not as much

I would say run that tank of gas down and fill with a good quality gas. You may just have some water in the tank.

Yes that'* my next step..just run until it may clean itself just added seafoam..ironically i wanted it to be the fuel pump so it could be over, wich raises a question: with my past 92 SSEI i just hade to change the pump not the whole assembly about 90$ i priced the fuel pump for the 2000 it was a little over 300$ for whole unit..when i asked if they have just the pump i was told not avialable..so would you happen to know if the pump is sold seperatley?

Have you taken a look at www.rockauto.com might find better prices. Another option is a salvage yard.
