I am pretty sure the fuel pump is fine, cant check again cause I just drained the tank, but I did hear a noise coming from there when I put the key it last.
I think I am incorrectly assuming a noise should come from the bay (no key in car), here is why
I remember once trying to start my car and didnt connect the battery well enough and all the power shut down due to not enough power to crank I guess, I went to the engine bay and tightened the battery terminals, and clearly remember hearing a distinct loud noise from near the injectors or something (my friend even made a comment). I do not remember if I had the key in the car or took it out, so now I am not sure if there IS suppose to be that noise or that noise only happens when you put the battery in while the key is in the 1st or 2nd position? Hopefully this means everything is fine with ECM. Ill get some gas and use that link to trouble shoot and report back. Thanks for the help Jim!
Also when I put key in 2nd position, only the "Service Engine Soon" oil and volts light light up, is this a sign of ECM?
EDIT just saw your post Derrick, no the Check Engine light does not turn on, I just put gas in it, I hear the fuel pump, I dont hear injectors priming, yes the orange wire is in and the fuses are fine. (maybe it does, see edit 3, in that case it does turn on)
EDIT 2: So no check engine, no injector priming, I assume its the ECM BUT the "Service Engine Soon" or SES light does come on, I think this mean something wrong with cam sensor.Going to go see if any auto parts stores rent a noid light to see if injectors are getting anything.
TL;DR
SES light on, no check engine light, no injector priming noise, fuel pump good. spark plugs sparking. Fuses ok.
EDIT 3: Sorry about beeing a newbie, is the SES light considered the check engine light? or are they two separate lights? I dont see where the check engine light is suppose to be.. my other car has both so I just assumed the buick did also
TL;DR
SES light on, no check engine light (or maybe yes if it is the same thing as service engine soon light), no injector priming noise, fuel pump good. spark plugs sparking. Fuses ok.
EDIT 4; Sorry about all the edits, but I pressed in the schrader valve and only air came out (I just dropped tank, cleaned it and changed fuel filter, I guess I have air in the line) going to compress the valve and prime the fuel pump till fuel comes out. Hopefully this is the problem, but I still didnt hear the injectors priming so probably not.
