I have a n '87 burban 4x4 with a 5.7L. I have replaced the plugs, wires, cap, rotor, and coil. The motor turns over just fine, and fuel is being deliviered via the TBI. I am lost! Does anyone have ani insight/ suggestions?

Welcome to AF, to be clear you have no spark, but the injectors spray, engine will not fire?

[Bryeguy]

Motor does crank, injectors spray, and no spark. You are correct.
