1G 4G63 N/T No Power, No Response, No CEL, No Answers.

So back in march we did a swap from the 1.8 to the 2.0 successfully. It's been running great for about 1000 miles, but my alternator died. At 800 (idle) RPM's, it was charging @ 12.35v, as you increase the RPM's, the voltage would increase as well. It was a used junk yard alternator, happy to replace it with a shiny new one. And with that repair, I lost ALL my horsies.

I cannot use 4th or 5th gear at all, not an option. Climbing hills must be done in first or second, depending on if I had a rolling start. Even at idle, if I hit the gas, the first response is to stutter and sound like its going to die, but usually recovers.

What I have done:

No CEL lights/codes.
Compression Test: All 4 cyl's @ 189psi.
Fuel: 93 octane.
Spark: Present
Fuel: Present
CAS: Checks out.
Base Timing: Looks okay, I'll admit that I didn't pull the drive pulley off but I have no timing belt cover, cams + oil pump + balancer shaft marks all line up.

I've pulled the vac lines from the FPR, no change.

I've pulled spark plug cables one at a time: Runs terribly rough, but does keep going.

I've changed the MAF with a known good spare - No change.

I've injected 10cc's of fuel into the intake: Same response as throttling up: Almost chokes to death.


Power Transistor: I did the test using the battery and light, and other battery: The light comes on but a bit slowly - I'm not shure of what to expect other than it coming on.

I have no ticking, no smoking, no smells, no leaks, no.... anything. No power either.

The only thing I have to go on right now is that PTU .... if the light comes on slow, does that mean its .... dying and just not there yet?

Its been done before, that could easily be the problem and that was going to be my recommendation, that or a damaged crank sensor during the job.
