When I did my L28et swap earlier this year, I also had the problem of no spark.
It turned out that I had wired an incorrect switched power, "acc" instead of an "ign" , wire to the ign wire on the efi relay. Hope it'll help.
Which wiring did you follow? My ecu is sitting on my floor as well.
When I swapped the l28et into my 260z, I had the problem of no spark, the problem was due to powering the efi relay with an acc power instead of "on" power.
If you wire the relay with an acc power it will cut power while cranking.
As for the injectors, did you pull the dropping resistor with the harness?
The dropping resistor are in series with your injectors, without them the injectors won't fire.
Here is a link to a dipole one http://cgi.ebay.com/ebaymotors/MARINE-AM-FM-ANTENNA-Waterproof-Dipole-Hideaway-45-inch_W0QQitemZ330259236466QQihZ014QQcategoryZ26451QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
I've seen a couple of antennas for this purpose. One is a wire dipole antenna. The other is a power amplified one that could be found in any part store.
EvilC, in the picture of your parts, is that just the lense or the whole projector?
Just a heads up, the last time I tried to retrofit into some cheap 7" ebay housing, the glass doesn't come off easily and cracks, it could have just been me.
I'd check out the replicas in person before buying... the padding and feel of a replica, not from this particular vendor, was really bad compared to the real thing.
You could try playing around with setting up resistors in parallel, just gotta figure out the correct one with the formula.
I can't remember if the running lights stay on when the brake lights are applied.
