    Last dizzy I swapped out I used a new one from AutoZone. Worked fine for me. Make sure to lube the o-rings with oil when inserting the new one to help things slide in. The dizzy I took out was very crusty and did not want to turn smoothly. Everything i have now is all sensors and no dizzy.

      I've rebuilt them but if you don't have a press to get the gear on and off, its not really a DIY-friendly task.

      have a close look at the coil connector though. Have seen the wires in those break right at the plug and do this. easier than messing with the distributor.

        Yeah I think it’s the pickup coil and I might just get the pickup coil only cause the car is pretty low mileage. But I think I’ll still do the whole thing just to ensure that if something else was the problem in the dizzy then I’d be fine.

          And if possible, could you show me the exact one you bought? If you can’t recall then it’s fine.

            to do the pickup you have to remove the gear. Its got a pin, then it has to press off. Shaft slides out, 2 screws and the pickup comes out. The extra fun part is getting it back together, the gear has to go on exactly lined up with the hole for the pin otherwise it will not go back together. I've tried getting them apart by heating the gear or just using a hammer and a pipe to drive it on, it doesn't work. At best it got stuck somewhere, at worst it bent the shaft or damaged the gear. Takes 2 minutes with a press but otherwise forget it.

              Yeah I don’t have a press and I’ve had my fair share of tedious tasks on this car… just ordered a whole distributor to save me the trouble. So when I put the new one in just dip the shaft in some 5W-30?

                just need some on the O ring, it'll oil itself with oil splash off the timing chain.

                  Just get the dizzy your engine requires. I also got the "new" one and not a reman one. Looks like the new one for roller cam 302 (5.0L) is https://www.autozone.com/external-en...d17/224372_0_0

                  That should be the one I used as well.

                  If you have a 351... use this one: https://www.autozone.com/external-en...d05/193734_0_0

                    New one just came in and I’m about to install it in a bit, and I have a 302. Didn’t get mine from autozone but I got the same one you linked.

                      New distributor just came in and still no spark. Kinda lost from this point, anyone got any advice? ICM been replaced along with the entire distributor, ignition coil, and ECM.

                        Is the smaller ground wire off the neg battery terminal connected and good? That is a main ground for the ECM. That sucks, good luck.

                          You mean the one located by the ignition coil? I can’t really recall I’m not home at the moment.

                            I would check EVERY ground wire on the car - even if they "look" good. Take off, clean and reinstall.

                              did you check to see if you have +12v at the coil, both key-on AND cranking? There are two power feeds for it and its very possible to have one but not the other.


                              contrary to popular belief, the ignition system in these cars is not reliant on the ECM. The ECM provides timing advance, but it will not cause a no spark condition, and you can crank the car with no ECM installed and get spark. Bad grounds are not going to cause any of this. Can cause other stupid problems, but not this.

                                Yeah I just started doing that today and I’ll get back to it later. I was kinda lost yesterday but I think I just got pissed off.
