Check fuel pressure and for sparks

Hi Allen,it's simple to do,don't have to remove dash,here's a link to removing the blower motor and nest.

You would unplug the injectors and check for voltage on one side of the plug and a ground pulse from the computer on the other. All 6 injectors should have battery voltage with the key on, and then the computer grounds the injectors when they are supposed to open.

i would check the fuse.

Start with the fuse box located under your hood. Open it and check the headlight fuse or fuses. If they are good, change the headlight relays.

use belt spray solution

sounds like an air leak. check all rubber hoses including the one to the booster . Check that any plastic fittings haven't cracked
