Hi I have a 1995 impreza L with the 2.2 motor and previously an auto tranny. I swapped in a 5spd from a 1997 legacy. I did the wiring myself wich include soldering the 11 and 12 pins together in the auto harness as well as remove the tcu and ignition interlock box. the motor will crank but wont fire, I have spark at all four plugs, as well as fuel as the plugs are wet and I can smell raw gas. Every once in a while it will catch fire at the throttle body as well as sputter and belch a white smoke from the exhaust, when I turn on the key i hear the pump cycle on and then off and then on then off then on,

does anyone have a jumping off point here

thanks

You screwed up the wiring somewhere. Did you make sure to plug in all the harnesses correctly and firmly? You may have spark, but it may not be at the right time.

he forgot to connect the battery.

-Almost sounds like you have the diagnostic connecters under the steering column plugged in if you hear relays cycling
-The car shouldn't stop running because you do a transmission sway, you may have missed or jumped the incorrect wire(s)

I will check on the diagnostic plugs

I did have the green plugged in. Unhooked now and still no start, next is test cam and crank triggers I guess

did you accidentally unplug something in the engine bay, like a sensor or something? its possible you messed with the wrong wires in the harness too. i've never done an auto->manual conversion though, so idk

 

[Silver600rr]

Original harness is intact. The only thing I messed with is the two 12 wire plugs that went to the auto

Did you short out the wires that used to connect to the auto shifter? I think one is the key lock, but I forget what the other was.

 

[Silver600rr]

Yeah they are shorted together to trick it into thinking its in nuetral.

Nothing related to the auto transmission would keep the car from starting up if it's already cranking. What you should do for longevity is wire those 2 wires to the clutch pedal switch or the neutral sensor on the transmission wiring so that it will only start in neutral as intended

I'm gonna say you screwed up something else unrelated in the process, but unfortunately it's hard to say what

Well just did a compression test and cyl#4 is dead no compression at all. I will check leakdown to determine rings or valves
