Whats Wrong?

Thats the thing with fuel pumps, you can't run them with an empty tank . They are cooled by fuel flowing through them. Also, if you run them low, you can suck up a bunch of nasty stuff....not good. I know how it is though, filling a 30 gallon tank isn't cheap.

The shop is going to do a pressure test. They think it's the fuel pump damn it!! But my BB PCM showed up today so I wil have fun burning off my full tank first!!!

Does it make any difference if the tank is empty or full?

 

[roadrageror]

Not a huge difference. Now when I give it gas tho I can hear a relay behind the headlight switch ticking til I let off the gas.... I'm lost
On the bright side my girl bought a 08 dark grey trailblazer last night!!! Not a SS but found lots of stuff for it.. Problly gonna take it on holidays now..

well this is weird..its better now. lots of power right outta the drive way! ive probally only gone 40km in the last week or less with 94 octane(and the BB tune) but all the hesatation is gone. im not sure what to think but im happy thats for damn sure..it was BAD for about 10-12 days straight and yesterday it is normal again,i took it for a spin this morning and still good.all i did was the fuel filter and better gas. so i dont know but ill see if it happens again..in a few more days,but if its better im gettin the A/C recharged.(it was still bad for 5 days after the new fuel filter)

well i dont know whats going on NOW!!! today my girlfriend started to drive her TRAILBLAZER that she has had for only 10 days and its bogging down and feels like its doing the same thing?? her RPMs wont climb and she got check engine light and other lights like traction control and others...my Question now is could somebody be messin with our vehicles? maybe putting somthing in our gas tank?.. hers is at the dealership right now and supposed to get looked at tomorrow,this is getting weird. i looked at the gas caps to make sure there was nothing i could see like another liquid or sugar or somthing..guess ill see what the shop says about hers.

Have you made enemies with anyone lately? Buy some good locking gas caps. Check and make sure you still have catalytic converters. There is a rising market for stolen cats. The theives are after the exspensive metals inside them. Where I live, the scrapyard will give $60-$90 for a used one.

But of course, if you had a hole in your exhaust you would definately hear a difference.

that clicking relay would have me worried. i wouldn't be convinced your problem is gone quite yet...
but if it is, good for you!
