Okay, just helped a buddy swap a new engine core (block and head - D15B2, if memory serves) into an '88 Civic with dual-point PGM-FI. Kept the original intake and throttle body, all wiring appears to be back where it belongs. Engine was running before, but there was a big nasty crack down the block right behind the #4 cylinder.
We're getting spark and compression, but no fuel into the cylinders - plugs come out completely dry even after much cranking. Fuel pump is working, and there's lots of pressure both before and after the forward fuel filter. Haven't checked where the fuel line bolts to the throttle body, but I don't expect there's a problem there either.
I'm guessing something is preventing the injectors from working (again, this is the same intake and throttle body that was in the car and working previously). Didn't have any time to troubleshoot it tonight, so we're back at it tomorrow evening, so I thought I'd ask here for some pointers on where to check, what to test, how to determine where the problem may lie - any wires to check for signal or voltage, that sort of thing.
Thanks in advance!
