I needed a new pigtail connector for my ignition coil on my 95 M6 Z28. so a got a new one spliced the wires and reconnected everything. No the car will not fire i know i connected them correctly. Also the abs box in the front right of the engine compartment makes a noise like a coin dropping into it on the inside of it when i just turn the key forward not when i try to start it. i dont know why it is doing that. The car was firing up yesterday and i could drive it normaly but when i tried to get on it the car just sputtered and back fired. I have a brand new starter, altenator, ignition module, ignition coil (msd), wires, plugs, opti, opti connector, map sensor, distributor and waterpump. I have no idea what the deal is. Please someone help me!!! im running out of things to replace.
