First of all i hate being a parts changer. Been dealing with this issue. Drive for 40 minutes, quits running, no spark code 306 today, towed home to shop,
i've replaced dist. pick up-crank sensor-cap-rotor-coil-checked and cleaned all grounds-has msd wires-replaced all fuses and Asd. relay all that's left is ECM.
this truck is perfect, no rust, stored in air cond. shop, 39,000 original miles, 10,000 on 408. Any ideas.?? Replaced parts because had new parts on shelf.
Thanks.
