my 91 accord wont crank will turn over but gets no fire or fuel?

do you have injector pulse?

Those cars have a habit of burning up their main/fuel pump relays. Usually they start when they are cold but not always. Other causes of no fuel/spark are crankshaft sensor failure, PCM failure(rare).

Do you have a multi-meter (voltmeter) to test for power at fuse box (to and from each circuit)? Ignition switch tested good? As already mentioned the 'main' relay under the dash on drivers side is a possibility , test for voltage to it. Also , maybe check all grounds that were disconnected during head repairs , in case one or more has poor contact.
