Wait a tick! Was cleaning up and I picked up stuff from in front of the car and I noticed the afm flapper door was in the up position... Bingo! Put in spare afm and Vrroom! The afm spring is unhooked or broken, the would explain the sudden death and the injectors acting weird. Ill post a video in the am. Thanks again everybody hopefully this will save some poor slob 3 days of barking up the wrong tree(s).

"you aren't really thinking things through. " What's good for the goose is good for the gander.

Nite folks, ill hit it again after work tomorrow. Thanks for all the advise.

Well, it sounds like youve never "grasped at straws" that's all the fuel damper thing was, a straw. Sometime getting distracted helps u figure out what the main problem is. Btw, stock ecu is non-sequential, all injectors fire at once. If you read the manual........

Your point seems pretty clear. "don't think that you understand the basics of fuel injection, or your not applying the principles to your problem. You should read read the Engine Fuel chapter in the FSM." That's ok man I still love u

Wait a tick.. somthing is amiss in AFM LAND........

Why would I be offended? I've been wrenching 25 years now, that's means I have enough experience and humility to admit when I'm stumped and I am. Stumped. I've delt with arm chair/walk up mechanics since Reagan was in office. I'm not gonna get worked up cause one MORE guy told me I don't understand basic fuel delivery principle. keep em comin NZ, its kinda entertaining.

Good points pharaoh, the cold start has been gone 4 years now. And yes newzed, my first stop was the usual culprits, relays, fuses, blockages and yes even the manual. If I come to the site I've exhausted all other options, spare ecu, pump, fpr, etc but I understand that u have to ask NZ because some guys view the hybrid z resource as "first stop" for me I come here when my car has been sitting a few days. I'm gonna chase a short in the fuel injector wiring for a bit. That would make sense with the way it just suddenly died. However that theory doesnt explain why it dies when pressure hits the system when I turn the pump on. (it will run normal on starter fluid)

Wish it was that simple but thanks for the advice.

Fuel damper. Wait a tick, the stock fuel damper is still in place. Ill remove that next and see what happens. I can't really think of anything else except the fuel pick up in the tank.

It will run for a bit with the injectors removed, it is a bit of a fire hazard, apparently.

okay now it's starting to get aggravating. replace the fuel pump.removed clean the fuel rail, new fuel hoses, Replace the ECU, replace the fuel pressure regulator, replace the fuel injector relay, and the fuel filter,. Try to start it and its doing the same thinG. it starts on starter fluid but again as soon as I turn the pumps on it dies out.this doesn't make any sense in starting to drive me crazy.

Possible, just pulled the rail exposing the injector tips while cranking. Weak spray at first the with a couple blips of the pump, then good spray patterns from all 6

Verified injectors, varified fuel pressure, varified spark.

I got A mystery on my hands. without warning my Z stalled and died. Everything checks out fuel, spark, compression. It will run with starting fluid. But as soon as I turn the pumps on it dies. But it seems to be almost electrical because it dies when the pump is turned on. Verified working injectors, verified fuel pressure, verified spark,. what would cause a motor to die when the fuel pump pressure hits the system?

more to come, just bought a welder and some other goodies.....
