I have an series 2 with a Series 4 N/A motor in it.
The last nine months ive been fixing her up, rust, suspension and such.
About 6 months ago i moved her out of the garage and in to the shop, no problems she fired right up.

Now as she is ready to go out in all her pride and joy, the damn bitch wont start.

I've got:
Fuelpressure
New plugs with spark
fresh rebuild with 1500 miles on it and 110psi compression
lots of cranking power ---- But no bang.

If I use "startgas", You know the ether based spray ****, it will fire right up, go to 3000rpm for a second and then die out.

I have checked the plugs, they are dry and has no signs of ever having been in contact with fuel
Could my injectors have seized up just by sitting for six months?

Any suggestions are eppreciated.

You have fuel pressure, but I suspect no fuel past the injectors. The either spray suggests that you have spark and no fuel. The injectors are controlled by the ECU.
If you have pressure the pump is working. The ECU is under the passanger floor board.

fuses ok? I know standalones have an injector fuse but cannot remember about stockers.

There's fuel in the secondary rail so te primary has fuel too.
I've asked the same question in the first gen forum too, tried a bunch of things to no avail

Will check trailing signal wire to the ecu tomorrow.

Stock ECU with stock AFM?
There's a fuel-cut circuit in there - might be bad?

Yes N322 and matching AFM
I'll look for the fuel cut circuit. Thanks

Kim

trailing signal to the ecu is there too.
approximately 10Volts to the injectors during cranking, my papers says 12Volts.

Voltage will be lower while cranking.

For ***** and giggles, check your fuel injector solenoid resistor, if you have the earlier S4 setup. Also, see if the fuel injectors are actually getting a signal and go from there. Like it's been said, could be just power supply related, as in fuses, main, or circuit opening relay (if you brought them over into your first gen.

Badabump.

Woohoo...

Got the damn thing fired up today, turns out that it infact was lacking fuel(as in empty tank)
I must have mistaken the fuel/air mist spewing out of the hoses for just being fuel under pressure

Anyways the car had a quart of a tank of fuel when she went into hibernation last year, and now theres nothing in it. Seems like the, allways broke, guy I share my shop with is about to be kicked out. He's a ******* BMW tool anyways
Well, not everything sucks about this dumb issue, I got some of all that wiring mess cleaned up and ripped out.

After 6 months of just sitting, she fired right up to 3000 rpms then settled down and purr'd like a kitten

Video from my cellphone, sry.

Good to hear and get some feedback, as most people don't.

I hope you drained the last bit of fuel which tends to be all crap. I'd also change the fuel filter just to be safe.
