sometimes car starts then dies right away
 

Sometimes my bonneville will die right after start up unless i give it some gas and at times i need to give it gas to even get it to start. why is it doing this

Is your check engine light illuminated?

If so..please use the procedure in Techinfo to pull the codes and post them here.

If not.. is the gas level low or any consistent behavior when it does it besides when you first start it.

dies
 

Yes pull the codes, check for vac leaks and fuel pressure at the rail.

Let the car sit shut off for at least 3 hours, then pull the vacuum line off the fuel pressure regulator. If fuel dumps, drips, or poors out of the vacuum line or the regulator then the regulator is faulty and you will need a new one.

ill try a couple of those things this weekend. thanx by the way my gauge cluster doesnt work and the only codes i get are for an o2 sensor and for qdm b. and how do i check fuel preasure?
