Question about 2006 Buick Rainier

1 Answer

Rainer starts but runs erratic then dies out. Step on gas pedal and sometimes it will rev up and sometimes not at all but it always dies out

Thought had water in fuel tank so added some heet Put in garage all day to warm up. Had problem before and this fixed it. But now it will start and then die out like it cannot get enough fuel. Could it be the fuel pump or fuel filter? Tomorrow will check on fuel pressure if it runs long enough.

Yes you will need to figure out if it is fuel or ignition to know how to proceed. You should have fuel pressure as soon as you turn the key on even if the engine does not start. And using starting fluid to boost fuel supply may help you figure it out.

SOURCE: 1999 Regal GS Super charged, Starts,runs 3-5 sec and dies

i gaurantee that it is the fuel pump ressistor up on the passenger side front behind head lamp assembly you will find the connector with two wires going to it. no need to remove old one install new one and connect wires to new one leave old in. dealer only part but not expensive. dont belive dealer when they try to talk you out of it. This is a kit to relocate a ressistor that has been installed in a poor location. I promise this will fix it. My wifes car did the same thing, took 20 minutes to fix and that is only because i am an electrician and am finicky about where to locate wires etc. the kit comes with installation instructions however they are a little vague. trust me. easy fix. my dealer tried to get me to leave car for repair and said it sounds like the theft detterent system. they were wrong and i was right. dont trust em

SOURCE: will start then dies

On the regals they have a ceramic resistor on the passanger side under the fender. It heats up and over time it tends to brake and the wire inside tends to rust away. The fuel pumps run in 2 different speeds. Had the same problem. Dealer only part yet the car would run and you would think it was the fuel pump. Turn the key it kicks on then start and dies out. Ceramic on the pass side would need replaced. It is white about 2-3 inches long or so held on with 2 bolts i do believe. Ill find a bulliten i found online to help me diagnos the problem. :) hopefully this helps someone out instead of spendin $$$ that ya cant afford with the recession eh?

SOURCE: Buick Regal dying

You have a problem in the fuel pump relay circuit for sure then. I'm betting the relay, but it could be that dropping resistor.

SOURCE: ran out of gas car wont start

first make sure theirs enough gas in the car now, about 5 gallons. next open the gas door, then the cap. next put your ear to the open fule filler neck. then have someone put the key in the "on" position so teh dash lights up and all, but dont start. this should trigger the pump to start, if you can hear a buzz then the pumps on and working, if not the pump is dead.if this is the case just be sure by checking the fuses to confirm. only way to get to the pump is drop the tank. also dropping the rear exhaust helps too.

Starts just fine but dies at idle. will keep running when stepp[ng on gas pedal


if the car runs fine at high revs, I suggest just turning the idle revs up 150ish, it could be a block cat converter, or restricted airflow making it die. but quick fix turn revs up 150rpm will do no harm and if it dies at higher revs, take it 2 the garage to see if they can find the thing.
