So for a while I've been having idling and starting issues. A few days ago it just decided it didn't wanna run. Turn it over, runs than dies, all within a second. Changed the plugs, no avail. Checked the fuel pressure, full pressure coming to the rail. Checked each cylinder, and theres spark going to each cylinder. I suspected the TFI module. I played around with the wiring, wiggled the harness, unplugged it, to no avail. My dad used this old school ignition box (i guess a way to test the distributor) He ran two leads to the battery, and then one wire goes to the coil terminal on the cap, bypassing the coil. supplied power to the distributor. Tried to start it, and no avail. So we concluded that it may be, indeed, the distributor.

We removed it and found that we can replace the pickup. So the plan is to replace the pickup and the TFI module. Upon trying to disassemble it, it seems that i have to literally break down the entire unit just to replace the pickup, which led me to think about replacing the entire distributor. Does anyone know if motorcraft still makes distributors, or who sells quality stock replacements? Would it be worth it to check out aftermarket replacements, such as the hot forged unit from 50 resto? I heard enough bad things about MSD distributors to stay away from them.


Thanks guys.

Stock replacement rebuilt is the way to go. About $100 at the parts store. There are multiple brands like the Richporter, but the general consensus is that they are all about the same.

The first timer can do it ,the cap needs to be removed note the position of the rotor, disconnect wiring to TFI module, take a sharpie and trace a line over the timing cover depicting the orientation of the TFI module on the distributor, take a sharpie and also mark the rotor position inside the distributor. Place rotor orientation Mark inside the distributor on new distributor, at this point you can remove the bolt holding down the distributor, you can now remove the distributor by lifting it straight up and replace it with the new one mimicking the old position exactly, both TFI position and rotor position. When you are sure everything is matched up correctly then you can bolt the distributor down and install the cap and plug in the plug to the TFI module. If done correctly no timing light is necessary, but is a good practice. I would refer to a repair manual also. Good luck to you!
 
My distributor failed and I replaced it with an MSD complete distributor. Been rolling ever since.

Someone posted on here some time ago that they went through a few MSDs in a row under warranty. They finally took apart the MSD and put a quality BWD pip in it and it went failure free for thousands of miles after that.
