cutting in and out
at intermittent times, my 86 just loses (fire) for a second or two and then regains it. it doesn't miss when quitting or refiring,, it does it at all rpms,,
any thoughts ? also,, where is the fuel pump on a 86 injected rx-7 ?

I'd be looking at the basics, like bad sparkplugs or spark plug wires first. When was the last time they were replaced? If you don't know on either, you should replace them anyway.
the fuel pump is located in the gas tank as most Fuel injected cars built in the last 15 years.

Its very common to have the pick up filter in the fuel tank get clogged and have the engine cut out, but only while turning. That is why I was asking.

it happens at all rpm's,, under acceleration or just cruising down the road,,, doesn't seem to be related to turning,,, and i can also say that none of the gauges react in anyway,, the engine just loses fire for a few seconds then runs strong again.

There are three coils, the leading and two trailing coils.
The tach signal is summed off the firing of the two trailing coils.
If the trailing coils go out, or were not firing then you wouldn't have a tach signal for the gauges, power steering, cruise, etc. The engine would still run, just slighty rougher (some people wouldn't even notice).

so,, it could be the leadig coil,, but this is complete cut-out,, i mean it shuts off for a second or two and then regains fire.
so,,, a bad ground sounds more likely,, u don't think a fuel pump would cause this ?
