Does the new pump run? if yes then is there spark at the plugs? also did you replace the fuel filter?
Make sure connections are on tight.
have you replaced and or tested both coils? are you getting no spark on the intake and the exaust sides?
most likely it is your fuel pump the same thing happened to my 1999 mercuy sable
i had similar problem with 99 wrangler and if its the relay its located in the fuse box.
Yes the alero does have abs it was and still is standard in GM passenger cars. Now that we cleared that up the light is on because there is a problem with the abs unit usually this is caused by someone not familier with newer cars changeing brakes and simply prying open the calipers without opening the bleeders. If this has been done the abs unit is destroyed and needs replaced. Also there is a rotation scenser at each wheel and on or all could be damaged such as the wires have been cut in some way or the scenser is bad.
my Oldsmobile alero did the same thing. It turned out to be as simple as a blown bulb in my tail light.
my 1999 alero speedomter started going crazy too and they replaced the wheel speed sensor and it still does it must be a short in the wire.
fan clutch?
Had ther same problem, ignition switch fixed it.
Make sure connections are on tight.
Could be thermostat not opening causing a back pressure
Check the fuse
You probably have a bad battery. You probably have a bad battery.
does that year have carb or tb?
Had a 93 Silverado that did the same thing. Had the electronic module replaced and all was well.
i would check if you have power to the motor from the switch
Dead starter?
