2002 buick rendevous won't start

I changed the fuel filter. I can hear the pump going and the filters getting gas to it. The car is turning over but it just isn’t starting I cannot think of what else it might be and it is stressing me out a ton. anyhelp or input would be appreciated.

The running fuel pump & fuel in the lines are certainly something. But it doesn’t tell you whether the fuel pressure is right or whether or not the injectors are firing.

Just do a basic check to narrow things down. First, use a spark tester or spare spark plug (or just pull a plug out) and check for spark.

If you have spark, shoot some starting fluid into the intake and see if that gets a hiccup out of it. If it does then you troubleshoot fuel.

You might also need to worry about the security system. Have you tried a different key?
