Hi John;

Congratulations on the first start.
Excuse my lack of attentiveness, are you running a carb + electronic FI /EC2 setup?

For the FI setup:
The first easy thing to check is the resistance of the injectors  - probably 4 or 14 ohms depending on the type (if working).
If these are used, high pressure rx7 FI's that have been sitting, they are most likely gummed up.
You can send them out for ultrasonic cleaning at roughly $25 per or do it yourself.

Sorry, no pics handy.  Lynn?
You can do a backyard injector cleanup / flow bench with micro clamps, 3' of clear hose with a fuel funnel,
gas, injector cleaner and high pressure air source.  A little duct tape or jig goes a long way for the 3rd
and 4th hand you need.  You will also want a clear jar or graduated container to inject the fuel into.

A 9V battery lead connected to a spare injector connector can actually drive most working injectors.
A battery charger is much better for the most gummed up ones.

1.  clamp the clear tubing to the fixed injector (probably best to inject into a sealed clear jar), (can't remember the tubing size)
2.  fill the tubing with gas
3.  clamp the other end of the tubing to an air source (say 50 psi)
4.  apply the air source to the tubing to push the fuel towards the injector (they should not leak)
5.  pulse the injector connector power source to open the injector.

You can run gas/injector cleaner through the injectors a few times until you get a good spray pattern and they do not leak.
Most? shops ultrasonically clean the injectors sitting in solution - I'm not sure how good that is for the plastic housings.

I have also heard it that you should not run the injectors dry doing this. (heat, sticking open?)

A fire extinguisher and friend aren't a bad idea.

backflushing the injector also helps with the really stuck ones - and also cleans the small screens.

Cheers
