Need help with TBI

[mudlover88]

I have a 88 K5, 350 TBI that has laid down with a no start issue. Have new plugs, wires, tps, map, esc, egr, egr sol, o2, new dist, coil, and yes new fuel filter. I have swapped the ecu, and the fuel pump relay. I have fuel at the TB, and spark at the coil. WTF am I missing?

Any blown fuses?

fuel pump? it could not be getting enough fuel, does it seem like it wants to fire? how does it act?

No blown fuses and looks like it's getting plenty of fuel. It cranks just fine but wont fire.

pull the injector connectors off and see if it starts and starting fluid, go from there, could be a timing issue or compression
