no fuel to injectors/not firing [m20]

[otto325e]

So far we have confirmed we have spark, fuel pressure, and engines cranks. The car will start for a moment when the cold start injector kicks in(eta) then it dies. The only thing we can think of now is the main relay but still nothing. Any ideas?

Check the connector under the intake manifold for corrosion.

I hard wired the 6 wires... just used butt joints to splice them into the main harness

My guess, since the engine briefly fires while the cold start valve is open, is a lack of fuel pressure, intake leak, or no firing pulses to the injectors. A noid light will tell if the injectors are firing. You can measure the rail fuel pressure. And a smoke test will tell if there are intake leaks. Do the diagnostics and you should be able to find the problem.

This is an ETA and thus it doesn't have a C191 connector under the intake. The injector wires are part of the engine harness.
