Make sure battery has a full charge and connections all good. I don't know what testing you have done? Key on, do you have primary voltage at ignition coil, pink wire, fuse protected, you can use test light to check for voltage. You can also check voltage at pink wire going to ignition module, it also is fuse protected. Engine cranking do you have proper fuel pressure and fuel injector pulse? Any applicable trouble codes?
