That’s a good point 67Dart273. I need to make sure wires are away from coil, plug wires, etc., especially that pink wire now that I think of it. As far as the fuel pump, yes theres a relay within the harness that I assume controls it but I’m not certain.

Thanks DionR. No, haven’t replaced the sensor yet. I never thought the ECM, hmmm could be. I wonder if a guy can test them?

So, I remove my Quickfuel 880cfm and Mopar electronic distributor and coil from my 69 Barracuda with mild 440 and install the Sniper 4140 EFI and Hyperspark Ignition (Distributor, Coil, Ignition Box, harness) system. Of course, there is no easy switched power so run the pink wire through the...

Excellent, much appreciated. Now, do you see any issues with using the relay with the "diode" in it, the way its wired in the picture? Or, should i just go with regular ol' relay? Thanks.

Appreciate the reply KitCarlson. Forgive my ignorance, but in the pic are these IGN1 and IGN2?

Well, I did as Holley said and grabbed a 5 pin relay with diode built in. I wired it as they said but of course coming from the starter solenoid the screen and fuel pump turned on but cut out immediately during cranking and wouldn't start. I saw another post on a different thread where one said...

I just installed the Sniper 4150 and Hyperspark Ignition in my 69 Barracuda with 440. All went well except for the dreaded 12volt switched source that is required. I have 6 fuses in the fuse box and none that have 12 volts while on and cranking, and off when the key is off. If I use my third arm...

Thanks 67Dart273 for your quick reply, as well as your suggestion KitCarlson. I did just that and started going over major connection points, starting with the battery, then bulkhead connector. Then got thinking about that rattling alternator, so checked it and sure enough........a wire, i think...

Hello. Running original wiring in restored 69 Cuda. Have the usual issues as with any other Mopar I've owned ie: dim lights, slow signal lights with headlights on, voltage shows low at idle, etc, etc. But.....the other day out for a cruise and all of a sudden my voltage gauge tach's hard to the...

Hello. No I wasn't able to get rid of it. Will have to try again in the spring as the ol' dog is parked for the winter now. Frustrating as hell though, but if one thing has been gained is my knowledge of that carb and knowing my way around it. I haven't fired it up in the dark and looked for...

Well....I tried 77's in the primary, left the 84's in the secondaries and found it really lean. Plugs where pretty white. So, went with one size smaller than stock with 79's in prim and 85's in secondary. Found this rich, strong fuel smell, and didn't get rid of my surging issue. I put the 78's...

Yes, I suppose it is two separate conditions. When cruising at say 40mph and step on it, it surges and jerks like its missing, or too rich/lean. The second scenario is at a constant highway speed (70mph) I can feel it surging/hesitating, just not running smoothly. Like its too rich/lean or...

After a few cruises, lowering my primary floats a bit, ensuring my timing is on with 38 Total/17-18 at idle, and setting the idle mix at all for corners and a fuel/air mix of 11hg, it seems the surging is happening under hard excelleration mid way through the powerband and not so much now under...

Nevermind, I see I'm in the Fuel And Air Forum. Thought I was clogging up the Electrical and ignition forum with my carb issue, lol.

Went for a rip last night with the 79's in the primary's, and found that it cleaned up quite a bit, So I went back to the 78's that I had issue with the first go around and fully expected it to be hard starting and backfire through the exhaust again. It didn't and fired right up, idled fine and...
