Hey I replaced the ignition coil, along with the rotor button and now my truck won't start, it just pops when you roll it over. I know I turned the rotor when putting it on and I think it made it jump time or something. Other than idk everything is hooked so I'm lost and have nothing to drive ugh please help guys!!

Re: No start after Ign Coil and Rotor Button change!!

Unless you unbloted distributor, and rotated it, you did jepordize timing one bit. Make sure you snag wire on coil lossing ground or 12V or arching out popping fuse under dash. What kind of coil did you put on? Even MSD is having coils made in China, so its maybe faulty. Reinstall the old one and see if you get it started. You can easily check for spark by pushing a spark plug onto distributor cap side plug wire with other side on new coil. Have someone turn engine over and see if you got spark jumping, should be quite visable. Now, irony has a odd way of showing its face. So after your tune up you may have lost the ignition module underneath rotor button. it happens bud, and are very prone to goin out.

What do you mean by you turned the rotor when you were putting it on?

Shouldn't matter - just verify that the rotor is indexed properly on the shaft itself.

Did you turn the distributor itself?

Hey didn't turn the distributor, it's solid. When I was putting the button on, I wiggled it around to get it on and it turned a hair. I just got one from advance auto, its the coil that goes on the bottom of the distributor. I didn't use any die-electric grease though. All fuses are fine I just can't figure it out.

Sounds like you installed an ignition module. Pull it, put dielectric grease on it, reinstall it, and verify that the plug to the pick-up coil and the weatherpack connectors are tight and secure. Verify that the rotor is installed properly on dist. shaft (it's slotted to match).

Yes that's what I installed. I noticed the old one had grease but the new one didn't. Could that be why its doing this? My boss told me to look at the pickup coil connector, he said they get brittle and could warp, so it's plugged in but not getting the adequate power right? I'm am almost positive it's on there correct, I mean it can only go in one way where it's slotted? I very much appreciate all the help so far guys! Hopefully I can get this thing running today so I won't have to catch a ride to work. Cheers!!!

Re: No start after Ign Coil and Rotor Button change!!

The grease is there to help conduct heat away from the ignition module, keeping it cooler, prolonging it's life and performance. The rotor is slotted at the "bottom" of the cavity and therefore, can fit onto the dist shaft in any direction. However, it will only fully seat when keyed properly. Check the connections, put some grease on the ign module (parts stores have the grease separately or you can use cpu grease from a PC shop), and verify all is installed properly.

Could the pickup coil have went bad from it being the only stock part in the ignition.

My call is if you think you have it together correctly, put the old ignition module back in. What caused you to change in the first place?

Re: No start after Ign Coil and Rotor Button change!!

The reason I changed it was for a tune up. From what I've read they can cause long start up times, inconsistent shift point and lack of power. I mean it was a tune up part from what I understand so I figured a new one wouldn't hurt. I was actually told by a member to change that when I go to do my tune up. Plug wires aren't cris crossed. But I'm here with the truck now about to pop off distributor cap and try a couple things. Anything else I should look at while I'm here? Thanks guys I cannot stress how much I appreciate all your help!!! :)

Here's how desperate I am, my phone number is 740-645-6096. I can send pics that way. I have the cap off, just put the new ignition module back on with grease, checked the three pigtails that go to it. The small two wire pigtail from in guessing the pickup coil, one of the pins on the inside when it would plug to the male end of the ign mod, was gapped a little bigger than the other so I prayed on it with a small screwdriver to close up the gap. I labeled my plug wires, and where they connect on the distributor. I am going to put the cap back on now followed by the wires, and hope she will fire up. I'll post back to let you guys know. Oh also, I was looking at the rotor button, and shaft it sits on. Well there was broken plastic from the previous rotor button, so I don't think the button could have properly been seated. Anywho new one is in, and seated, so yeah fingers crossed lol!!!

I'm just the opposite. I have three 4.3's here with over 200K miles that have their original module, but the pick up coil has been replaced because it went bad. 3 of 3. Bad coil, original module. Your results may vary.

Re: No start after Ign Coil and Rotor Button change!!

Hey guys I got her!!! The tab on the inside the old rotor button had broken into the shaft. So that wouldn't let it get seated properly. I put dielectric grease on the bottom of the ignition module, and on the two terminals that connect to the pick-up coil to the ignition module. Also there's a pigtail connector under ignition module, three wire connector I think. Well I saw it and unplugged it because it was like soaked in oil. Pulled it off, cleaned it, dielectric greased it and re-connected it. Them I put the cap back on, followed by the plug wires. I also marked the numbers on the distributor cap, and levels to the plug wires to the corresponding cylinders. Thanks guys I really appreciate all your time and help! Now I gotta get these tail-lights working.

See, that's why I'm not a betting man.
