car not starting after removing dash

my car has been having trouble starting because of a weak batter and leaky injectors. the day before i installed a kill switch, tested it and worked, started the car at least 3 times and killed the car with it, all good. so the next day i decide to replaced my ac condensor fan behind the glove box and the heater core as well so i removed the dash i tyed starting it without the dash or steering wheel on just bare and it didnt start so i put it back together thinking there was a harrnes on the dash that required the car to start but it still didnt start, i tryed deflooding, jumping and installed a new battery still no go. it cranks but cant turn over, i just installed new starter and sparkplugs so i should be able to rule those 2 out. i dont understand why its not starting i didnt do anything but remove the dash, it worked fine the day before.

Did you use oil when deflooding?

Prob some loose wire or connector not being put back together. You did turn the kill switch back on right?

Plug The RELAY back in,that is Under the DASH.it is a Black Relay that goes to a Five pin White Female Connector.
I will BET you 50 Bucks,that you have NO FUEL.
check that by Taking the Rubber line OFF the primary Inlet Hose.(that is the Rubber line that Goes From the Filter the Engine).Roll over engine,NO fuel Right???
I'll also Bet that your Plugs are Bone dry..
NOW,put that Relay back on,GET A RAG,put over the Fuel line.Crank..HALF A SECOND!(it WILL SPRAY FUEL SO BE CAREFUL!)
There ya go.Put the line back on.Start it up!
Trust me,I just Fixed a Buddy's car.he did EXACTLY the same thing.

The ENGINE fuse powers that relay (and fuel pump) and also powers the Main Relay which in turn powers the coils/ECU.

The ENGINE fuse gets powered from the ignition switch if the key is to ON or better.
