Fitech RPM Noise Code

Do your spark plug wires have RFI or emi suppression built into them?

I have these https://www.summitracing.com/parts/...MIy_yO-sKr6wIVZRh9Ch2bwA9qEAQYByABEgKE-PD_BwE

Going to read about this more. Thank you!

Hey mduenas, do you still have the Pertronix HP 510 installed? If so, connect the tach wire to the grey wire coming off the box.

I had it wired like that. No change unfortunately.

I can’t believe it! I got the truck to crank and sputter. No rpm noise code. BUT it won’t stay running. Just shuts off immediately. No codes. Didn’t change timing. I did however change my ignition module in my distributor. Put my old pertronix back in that it worked with before with a new module inside. I have spark but won’t run. Any ideas?

I hope you've sorted this out by now. I was having similar issues earlier this year and instead of the engine shutting off I developed a horrible misfire (I was using the timing control settings). I tried everything, replaced the coil, replaced injectors, replaced the magnetic pickup in the distributor, replaced the o2 sensor, wrapped everything in foil and nothing helped. It ended up being my spark plug wires and coil wire. I started my engine at night, in the dark and you could see electricity arcing from all of the ignition wires onto the efi unit, heater lines, anything metal, it was crazy. I relocated my coil closer to the distributor and replaced all of my spark plug wires the next day and the problem was gone instantly. Id highly recommend replacing your wires, mine ran great for two years before this problem developed what seemed to be overnight.
