1999 Subaru Legacy 30th anniversary edition
5 speed MT
ej22
Car starts, runs for a few seconds, then dies, will not idle. With proper TPS adjustments car runs without MAF connected, but dies as soon as it's plugged in. Car ran perfectly healthy until I replaced coolant temp sensor, tried putting old sensor back in, did not help. Tried pumping gas while starting car, caused motor to sputter,buck and die.
Whats new:
MAF (has been replaced three times over the course of two weeks)
TPS
PCV valve
Hoses that connect to the PCV from the torque box
Battery
Thermostat
Coolant temp sensor
What's been tested:
Fuel pressure within spec
gets spark
gets fuel
All sensors have been back tasted and are receiving and putting out the proper amount of electricity.
Smoke tested for vacuum leaks (there were none)
I have absolutely no idea what could be wrong, after the extensive amounts of diagnosis I'm at a standstill. Any suggestions would be appreciated.
