Hi folks, new to the forum and new to diesel truck ownership also. I have a 1990 F250 7.3 IDI, had it for about a year. Had a local mechanic replace the fuel lines recently due to cracking, and since then it's had a hard time starting when cold. It'll cough a bit of smoke right away, like it wants to catch, but then takes 20-30 seconds of cranking until it actually starts - at which point it runs a bit rough for a little bit longer. Before the fuel lines were replaced it started up just fine. Oh also there is a clicking sound after the 'wait to start' light goes off before I turn the key to start. Is it possible the mechanic didn't reconnect something needed for the initial feeding of fuel at startup? Or something else?
