D16Y8 Engine Swap

[civic lx]

I have just completed my swap. I converted my 91 Civic LX to OBD1 with a Boomslag Harness/P28 computer. Everything looks fine but I can not get the engine to fire up correctly. I've charged the battery, double checked the wire conversion, installed a new fuel filter, and checked the fire at the cap and plugs. The moter will fire up but it is running ruff, and if you try to give it any gas it will just die. If you cycle the key 2-3 time to make the pump pressure up it will fire up shooth and then rev up about 500 RPM and than die.
My thought is that my fuel pump can no longer keep up with four injectors, compared to the Primary/Sec. of my old engine. Plus will changing the filter I cycled the ign. switch the remove the air, and could only get a low volume flow from the filter. Thanks if you can help!

Are you running obd-1 electronics? i.e. dizzy, intake sensors, o2 sensors?

No I am using mostly all OBD2. Dizzzy has been converted to work with the new harness, ( installed OBD2 plug onto my harness) Basicly I installed the complete motor, converted over the wireing as in the Boomslang instructions.

You need to have all obd sensors match. My guess is you're confusing the ecu. Also, there are a few similar wires that may be wrongly connected at the IM.

Yeah man, all your obd sensors have to match the ecu, like turtle said. You know, you can run the y8 perfectly on obd-0 electronics, if your not looking too much into tuning. The A6 dizzy bolts up perfectly to the y8 head as does the A6 IM, might want to look into that.
