Problem:

Cranking the car will do nothing. Cycling the cranking (crank for a bit, off, crank for a bit) in quick succession will bring it to the next point in a couple of tries.

While cranking, car will sputter for 4-5 seconds, but will not start. After the 5 second, it just cranks (like it would if it was flooded). Turn the key off and then crank again, it will sputter for 4-5 seconds again. Will do this all day or until the battery dies. Deflooding procedure yielded nothing.

I've Checked Air: Vac Line Simplification, Full block off kit used.

- Map sensor is working as it should.
- No vacuum leaks
- Throttle body, cable and TPS have been adjusted.
- IAC is off/removed.

I've checked Fuel: Factory Spec Primaries, 1680cc Secondary Kit

- New Fuel filter
- Proper fuel pressure, no leaks (pressure holds after pump is shut off)
- Primary injectors were replaced by freshly rebuilt and tested injectors.
- Injector wiring was checked with NOID lights
- Myth about secondaries firing on startup and causing flooding condition debunked via FSM and NOID lights
- Injector plugs are in the right order
- Fuel lines are in the right order
- Duty cycle avg. 2.5-3% while cranking

I've checked Spark: Factory plugs, Magnacor wires, HKS Twinpower

- New plugs, cleaned after each starting attempt.
- Twin power providing wicked spark on all four plugs.
- CAS connectors plugged in, right order.
- Cranking timing is 1º and 7º while cranking?

Compression

- Motor was just rebuilt. I don't have numbers. Pulling the leading plug results in solid, even sounding pulses on both rotors. Front does sounds quieter, but still even and it could be muffled by the PS. I'll get a second set of hands and a cheap compression tester and see what I can see.



Sorry for the long read, just trying to be thorough.

The only thing I can find that doesn't work is the coolant temperature sensor (feeds the gauge and the display on the PFC commander). Broken wire (I'm assuming, as I already replaced the sensor) somewhere along the line. Still need to fix that. It reads 4.99 volts on the Commander, could that be causing an overly rich starting condition?

Going to try and pull start it tonight. Does anyone have any suggestions on what I may have missed in the meantime?
