What do you mean by saying 'chicklets'?
thanks

Mallory Ignition Coil MAA-29219
Malory Resistor MAA-700 (but any standard resister ballast would work, including the one you already have)

sergey it looks like you're getting into it at least so that's good. In the future it may help to try to do some searching around on terms you may be unfamiliar with, as you'll usually be able to find your own answer faster than if you just post another question and wait for us all to answer.

Sergey - I fixed this in Josh's truck doing the double chicklet trick. Google the Mallory coil you have and see if it has a 12v out put. If it does it's not right for the truck. You can either work around it using 2 chicklets or replace it.

First and foremost, you do NOT need the relocation kit or the amplifier module so cancel that order.

Second, I would recommend not bypassing the filter (little black box). If the problem persisted without it in, then it is working fine and it can save your optical sensor in the distributor.

Third, what coil is that? Is that the Mallory 30451? If so, you don't use a ballast resistor with that coil.

The double chicklet may, however, be a good idea.

The ballast resistor gets hot a lot (it is a ceramic resistor, the white thing). This is typically just used with the Mallory and the canister style coils.

Read through this and pair your system accordingly. It's fairly straight forward. It seems you have a few redundancies. Did you buy this truck with this Mallory set-up?

Morning

As someone else mentioned/asked, can someone shine some more light on what chicklet are and where to put them?!

I have the Mallory distributor and the ecoil as well. My truck had similar symptoms and maybe that's what I'm missing?!?! Fingers crossed b

Guys
I replaced the ignition coil and removed ballast resistor from my mallory setup
no luck - it ran for a 20 seconds and then shuts off

Does the ECU do a voltage divider? It feels like just putting two in serie is kind of random. I think I would have gone with a voltage divider outside the ECU circuit.
Just that means we can check for (9V) voltage at the ECU side right? So he should confirm seeing 12V.
Can he also use a 9V battery to at least confirm that with 9V is ECU is just plain happy (I.e. Disconnect the coil side and replace by a 9V battery input).

That's what I am thinking indeed. And 9V battery is easy to get!

remove the in-line black box filter I'd mentioned earlier just to check. Also what have you done about the chicklet? Anything? Confirm all of your 3 wires coming from the distributor are properly connected inside of the Mallory plugs they provide, as they're notoriously flimsy. I'll send you a PM I'll be out in NJ this weekend.

Check the unilite optic module in distributor-- it is easily damaged by voltage spikes. Rule that out/in first.
