I have a 91 Caprice that I just changed the alternator and had the battery checked. I was on the highway and tried to give it some gas and it just gave out. Started to coast to a stop, it wouldn't start up again. I've heard everything from dirty/clogged fuel injectors to worn out alternator. Anyone have any ideas.

Do below to determine if its fuel or spark issue

Disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, distributor pick-up coil, ignition control module, cam and crank sensors- Note: If it doesn't apply disregard it
