no injector pulse
Have power to injectors, have spark, checked ground back to ECU, all wiring is correct, tried another good ECU, and still no pulse.
What should I check? Crank angle sensor? Tach signal?

Get a NOID light from a local parts store (NAPA is the only one I know of that stocks them). Plug in the NOID light and unplug the rest of the injectors and the disconnect the 2 wire plug on the distributor. Then crank it a couple of times to see if you actually have power and ground. Remember that the ECU grounds the injector out to cause it to pluse. If it still doesn't work then replace the injector.

I had this problem once, The injector circuit on my ECU was fried. Had to get a new ECU.

Re: (devnull)
Just an FYI for those of you that search this in the future, the problem was the Boomslang OBD0 to OBD1 harness. I have seen lots of people post problems about this harness and EVERY time Boomslang gets in the thread and says that nothing is wrong with their distributor wiring in the harness.
Well I am here to tell you that there is. It actually fried this kids ECU and cost 3 days of troubleshooting. So when Boomslang comes on here and says there is nothing wrong with the harness...that is complete BS. It is exactly what I have read in the other threads.
Hey Boomslang, when are you guys going to fix the problem instead of bullshitting everyone and trying to save face?

i had a problem with similar harness. it wasn't the harness that was bad though it was the two of the sensors in the distributor that were crossed up due to incorrect wiring diagrams in the manual that came with the harness. Also caused me a whole day of time and money

Re: (johnnylaw)
UP...
I am having this exact same problem, without a boomslang harness.
Any help from anyone would be GREATLY appreciated.
OEM injectors, NEW distributor, NEW plugs, NEW starter. ECU confirmed to work and idle a friends car, used the same basemap on mine with no luck.
Please, any input? I have used an oscilloscope to try and catch the pulses but all I got was a voltage drop
