tank86

so i had a catted x pipe installed, and while driving it would make a "popping" sound and then finally accelerate. well today it bogged, popped and popped some more, and then wouldnt accelerate at all. it just coasted and was riding at 3k rpms. i parked it turned it off, and got back in a few hrs later and it wouldnt start. what gives?


so today i swapped the spark plugs and 02 sensors. got back in and realized that my fuel pump was not cutting on (priming... whatev)... i dont know if the above are related but now i have a larger/more complex problem. i am assuming the fuel pump is bad. any way to tell?

Clean your MAF sensor

tank86

would that cause the fuel pump not to prime?

no...

turn the key on and check for pressure at the rail
