A lot of cranking will run down the battery. Make sure the battery has a full charge, you can't test anything without a full charge. Intermittent problems are a pain to locate. You have to test when the problem is ongoing. When the problem occurs, have a helper crank it while you visually check for spark at the plugs, if spark everywhere, use a gage and check fuel pressure. You may also need to use a noid lite and check for injector pulse. An intermittent rpm signal is one possibility. There many possibilities?
