'88 Civic starting problem
 

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!
