Question about 1999 Pontiac Bonneville
Takes several attempts to start at a sputter then dies and has a metal sound when it happens. New battery and alternator and also plugs and wires. fuel filter also replaced but did not appear to be issue
Who does all your vehicle work?
You don't replace parts until they fail,
or are very old, like a battery & plug wires
last for 15 years.
That is called preventative maintenance
You don't do all that in an effort to diagnose a
current problem. You find out what is wrong by
proper testing & have to be aware of past maintenance
items & previous work done in the past year or so.
Other than the battery, there is no reason to suspect what
other work was done.
You have a fail to start or difficult to start condition.
You immediately check fuel pressure & the ability to
hold pressure & volume delivery over 15 sec
On a 1999 the fuel pump is probably worn out
If fuel is ok,you check for spark,it may be there but weak
There are other things that can be checked out as well, ,depending on what the car is or isn't trying to do

thers a oil psi senser that wont let the fuel pump run at low psi when the car worms the psi gos down ,the fuel rely only runs the pump for about five sec as a primer then the oil psi senser takes over thirs a plug righi behind the oil fliter for the senser ,un plug it and put ajumper wire across it as a test ,you may need a oil pump

Probably need the computer reset. All these cars now days are set up for the dealer to screw you. The fix yourself is about history

HEY!! I had same problem and i didnt know i solved it til i put in a brand new battery! I think the battery was getting old, and the extra amps told the 'computer' that the car wasnt running and it just died at start up sometimes. the new battery must have kept the computer from 'glitching off' when we started it. and all is great now!

Possibly a weak fuel pump, idle air control valve, vacuum leaks, or loose or damaged wiring in the ignition system. Check for vacuum leaks first. That's the only one that won't cost anything. Make sure all intake bolts are tight, and all hoses are connected properly and in good condition.
