NEED SERIOUS HELP

Ok so my car wont start.

i started this mornin by gettin a coffe and commin back between 6:30 to 9:00am took the dash appart and made a custom hosuing for my stereo and placed it in where the oem was. I drilled two holes right next to those two tabs in the back behind where the oem deck was. Then i placed two small scews in there with a plate i made to secure the back of the new deck. Went and painted my grandmothers house came back 20 min ago and wanted to take the car for a drive no go.

1 Its getting gas to the fule rails
2. there is blue aprk when i turn over the car all 3 coils good.
3 It is cranking
4.Battery is charged.
5.ANY SUGESTIONS?

what kind of tools do you have access to?
maybe use a noid light on the injectors if available - if they aren't going, check all sensor connections & fuses, wiggle all wires n stuff, check fuses in drivers side panel and under back seat, spit on it and call it betty, stuff like that

well i dont have noid light so check the injectors? Can i just pull each one to see if it spits? As for fuses i checked all them and i checked all the relays in the back. Maybe i drilled into something the place i hit was metal right behind the oem stereo theres two clips there that look like there holdin the vent to it? i barley went through the metal just enough to for the screw. Is there a wiring harness back there i might of drilled into? Myabe its the computer?

I can't remember exactly how it looks but I cut the whole back out of the plastic behind the head unit with a dremel and didn't come close to damaging any wiring but i could see a drill being a different story

you know where the orginal braket was right below it it bent back to the plastick you cut out there was two holes that went to metal with the back side of pish clips in them remeber you would of needed to cut the plastic there and down for your deck? I only went through not all the way for a screw.

ok update there is 42 wires right behind that little flange crshused between it and the vents. just finished repairing and complete reasemble 10 hours dam it was tough
