Starting issues - what to check
My 2.5 NA has just this morning developed some issues turning over. When I turn the ignition key (after letting the glow plugs glow for at least 20 seconds) the engine makes a quick attempt at turning over with a small puff of black smoke, before giving up and then the starter motor just spins. All of the electrical connections appear to be in good shape, the battery is fully charged. Any suggestions on what else to check?
