I Have To Drive The Ford Today
Yesterday when I went to start my truck it wouldn't. It sounds like it only is firing on one cylinder. It has gas to the carburetor, and I have switched carbs. I think it has something to do with ignition. It has HEI. When modules have gone bad before, they won't fire at all. Could the coil be bad? Any other ideas?

Re: I Have To Drive The Ford Today
Mine did the same thing when I forgot to run a new 12 volt dedicated wire to the hei and get rid of the restricted wire. Put in a new 283 and forgot to run the wire, it lasted about 600 miles then it was on, no more run. Ran a new wire and runs like a sewing machine.

Re: I Have To Drive The Ford Today
Modules will do a partial fire.

Re: I Have To Drive The Ford Today
I guess anything is possible but I've never had a module partially fire.
It's easy enough to check if all the wires are firing with a spare plug and clamp grounded to the engine. Or, a timing light clamped to the wire while cranking. Also check for pin hole in rotor, loose crimps or loose electrical connections. |

Re: I Have To Drive The Ford Today
Alright guys, he didn't have to say he drove the F@rd. He could have just posted the problem. The way I understand it seems that he's disappointed in having to drive the F@rd.
Now it's time to help him with his problem. It's a legitimate post and he want's some answers. |

I tried running a wire directly from the battery to the dizzy (still dead). I will go inspect the cap/rotor and swap modules. |

Re: I Have To Drive The Ford Today
I have a Delco HEI in mine and the modules fail often. All of the failures occur after I shut the engine down. It's such a common occurrence, I know if I crank the engine for more than 10 seconds, it means the module is dead. I have tried every brand of module out there and none seem to be any better than others. I always keep a spare module in the truck.
A few months back I installed a PerTronix D2070 Race Module. It only draws 7.5 amps and it has actually lasted at least 3x longer than any other. |

Re: I Have To Drive The Ford Today
Just swapped in the module. Runs like a top. I only have about 1,500 miles on it. I used lots of dielectric grease too. I wonder if we can buy USA ones?

Re: I Have To Drive The Ford Today
Most of the time if it is eating modules , it means something is not up to snuff.. marginal wires , cap rotor , something is taxing the system and the module is the first thing to go ....

I'm also quite sure nothing is amiss with my wiring. |

Where can I buy heatsink grease? My wiring is up to par. The cap and rotor are new too. |

Re: I Have To Drive The Ford Today
Dielectric = non-conductive. The stuff included acts as a sealer and meant to be applied sparingly. Which is why they give you such a small amount.
Heat sink grease (aka-thermal grease) can be had many places. There a Radio Shack near you? http://www.radioshack.com/product/in...ductId=2102858 And I own a Fox Body Mustang by the way. In addition to what's in my sig. ![]()

Re: I Have To Drive The Ford Today
Make sure the ground strap between the coil and the middle pin of the connector coming up from the module is there.
The coil is strong enough to arc the inch and change from it's body to the connector pin without that ground strap, but that will kill coils and modules. The missing ground strap and missing heat sink grease are the two main killers. |
