NEW $2000 HOLLEY SNIPER LEFT ME STRANDED

My New Holley Sniper system has crapped out after only a few months. What went wrong? Troubleshooting it only leads to a failure on the Holley system itself.

I went through the Sniper nightmare 5 years ago. Took 3 units before I got one that worked. I ended up going back to my carb. You can read my lengthy review on Summit's website.

Anyway I jumped back into the EFI mess last summer and installed a Terminator in my Dodge 440. Has worked much better than the Sniper. Few months ago it started to randomly miss/backfire during cruise. Finally found out the Dual Sync distributor was the culprit. It was losing sync intermittently. Put the MSD pro billet distributor back on and no more miss/backfire.

Although I am sending the Dual Sync back since its under warranty I honestly doubt I'll put in back in. Having control over the timing is nice and all but it seems unnecessary in my application and not worth the worry of it acting up again. Plus the motor starts right up instead of the 2 second sync delay with the other distributor.

Power probe is dangerous if you are unsure of how much power a wire or circuit is supposed to get. Say something ecu might only get 5V, but you put 12v to it, that messes up the circuit. I don’t use the power probe on anything no with an ecu. I just use a multimeter.

Oh boy now Iam second guessing this Holley swap on a customers truck. I subscribed to catch the follow up video on this. Thanks for posting

All my V8 engines have tow hooks attachments point welded to the bumper (could be bolted on) just for this reason. I stopped paying for tow trucks a long time ago. Esp my daily which doesn’t seem to fit and AAA won’t tow.

Believe I'd put the carb back on at this point. Just think, for another couple thousand bucks you could Cummins swap it and get 20mpgs lol

See if it runs with you hei at least you could drive it till they back in stock with what you need

It seems alot of people on you tube have bad luck with this setup. I see sniper kits used for sale more and more.

I totally understand what a headche... absolutely not plug and play I wish Holley would do something maybe reach out and take care of people with awesome cars cars so that it will run noemal

Where there is a will there is a way. First thing I don't know that it's fair to say that the $2, 000 system failed when you bought a second-hand CDI box LOL. But how about buy a new CDI box if all the numbers are still correct send the old one back as the new one and ask for your money back. It seems as though it's dishonest but it is a loophole in their return system. If nothing else you can possibly negotiate Holly credit it looks like you would use that eventually also.

You think the terminator efi is better?

[vidalmiller]

Also do yourself a favor and shrink wrap or zip tie Injector plugs they are cheap and clip sometimes come off

[nicklang]

Why not stick with the HEI setup in the first place.

CDI boxes unfortunately have a reputation for reliability issues.

I have my sniper setup controlling my factory HEI distributor. Easy.

[WTFSTOUT]

wiring looks bad...like bad install....sniper is questionable but at least do a good install
