But wait before you spend all the time tryin the figure the problem, try this I had the same prob look under the hood just in front of the battery it is a fuse box that holds the fuel pump/injectors fuse on the side of the box is the panel that tells you were the fuses are locate that fuse and see if its blowed it should have f/p injr on it, if its not blowed then the above reply maybe the cause

That's the fuse box. There's dozens of things that can cause the injectors to not spray fuel. First you have to determine if you also have no spark. Don't get hung up on the first thing you find missing. Loss of fuel AND loss of spark cause about 95 percent of crank / no-start problems. To add to the confusion, that loss of spark and fuel will also result in the pump not running during cranking, but you'll still have normal fuel pressure because the pump still will run for one second each time the ignition switch is turned on.

This post is eight years old and the person never even bothered to list the engine size, mileage, or other requested details. You need to start a new question, and please include that information, as well as any clues, history, or observations that can help in the diagnosis. When you piggyback on another question, this is a private conversation between two or three people, and none of the other experts will see your addition or have a chance to reply. That does you a disservice.
