After installing aftermarket tach the truck will not start

Hey I’m new to the website and I’m not 100% sure if this is the right place to post this but in my 1986 k10 I wanted to add a aftermarket tach so I installed it and hooked it up to the tach port in the hei but it will not start. I have unplugged the tach from the hei and the truck runs. I relooked over the instructions and looked all over trying to find out why it’s doing what it is but, I haven’t found anything about the problem I’m facing. Any ideas?

Did you wire the tach correctly?

I believe so I’m going to double check again but I just hadn’t been able to find anyone talking about a no start issue after installing one

Wiring can do weird crap if not hooked up correctly. Or in proper working order.

What brand tach?

It’s a equus tach I might mess with the ground and see if that does anything I’m just confused with it preventing it from starting
