[QUOTE="ytradio, post: 439165, member: 19779"] Part of the reason that I would attach a remote starter button under the hood is that it makes it easier to check for fire on the ignition system. If you have a faithful companion that can help, you will not need this, but I always am working alone. Even if the timing is too far off to run it will show whether or not it is firing. Start at the plugs first, if no spark there then move to the coil. You will just have to run back the ignition system until you have spark at the plugs. If it still doesn’t run then work on checking the plug wire firing order then setting the timing. It’s possible to have everything right and the distributor be out 180 degrees. If that ends up being the case, pull it and turn it around. [/QUOTE]
