Customer Question

I have a 89 gmc pickup truck that went under water in the flood. we drained the gas, oil, changed plugs, changed oil filter, fuel filter, and fuel injector but it still will not crank. It looks like gas is not coming through the fuel injector. What do you recommend? Could it have jumped time, could it be in the electronics, or what? Your help is appreciated.
