No Start Condition - please help!
Just finished rebuilding my classic yesterday, and having no luck getting it to start. Cranks and hits evenly, but only runs on 2 cylinders

Cams confirmed to be timed correctly (10-12, +20 rollers) and verified by compression test.
New fuel filter installed
Fuel pump IS priming and making correct pressure
NO vacuum leaks
swapped ECUs with no improvement
swapped igniters with no improvement
fresh gas and octane booster in tank
all fluids nominal levels

The only thing I can assume is that it would be an injector - how can I test an injector? Any advice would be greatly appreciated - I want to drive my car since its been sitting for over a year.

Easiest way is to run +/- leads from the battery directly to the injectors one at a time. Touch ground first, then positive and listen for clicking of the pintle. This is just to verify that the injectors themselves do what they're supposed to when power is applied. IF they're good, you need to look elsewhere.

a easier wa to test the injectors to see if they are clicking is to pull the distributor, rotate it, and see if the injectors click and the fuel pump comes on, that way you can hear them firing indiviually

Problem solved - two injectors frozen open - replaced with spare set, and now all is well. Thanks for all your help!
