i don't have msd i have a hei only, the fuel pressure Gage never drops below 5 psi, do i need a msd?

Also disconnect tach.

Change the HEI cap and rotor also, any HEI will work your
just testing to see if it runs fine, if it dose you can repair or
replace yours then, but that take the whole dist. out
loop completely.

No you don't need a msd if it ran before it'll run again (I don't need no stinking msd).

Need to look at that HEI module. I had one in a car I was trying to sell. It ran me through the ringer. I bought and tried 3 different modules before I bought an MSD replacement, and that fixed it. If you know somebody with a distributor machine you might want to take it there and have it checked out for yourself. I've heard GM had different part numbers for modules, and the ones that came in the HP cars were the ones to use.

Todd's right. You can actually have it tested at your local Auto Zone store. That's if you're lucky enough to find someone there that knows how to do it. But, "they do" have the machine.

Make sure your secondaries are opening too. Don't ask me how I know about that. Hahaha
