89 Camaro multi port injection 2.8L

Hello, I have a 89 Camaro and I can’t get it to stay running for ****. It cranks, starts for a second then dies, I have a new fuel filter, new fuel pump, new fuel injectors, cleaned the fuel rail.. the car already has the vats bypass with the relay, I don’t know 100% if it has the right fuel pressure but after changing everything idk how it couldn’t I tried the screw driver test it sprays gas so hard it hits the hood. I’m super lost just need some help to see what I need to do next

One possibility, although possibly remote, is that the ignition switch is only supplying power to the col when in the cranking position, and does not provide power in the run position. A jumper would be one way to eliminate that possibility.

im now to put a new distributor in because I believe the coil was bad in it. I do have a fuse that blows under the dash I haven’t been able to find the short yet. The fuel pump is hood up to a jump box rn to power it.
