A friend of mine has an 89(I think, but that era anyways) accord with a 4 cylinder, that is not producing a spark. I have never dealt with these before. The wire connections were solid and the wires looked good, but when I tried to produce a spark by grounding out the plug against a motor mount and cranking it over, nothin. IT cranks just fine, and there is plenty of fuel, just no spark. I couldnt locate a coil to check the connections there, and under the distributor cap was more plastic. Any ideas on what I could check here? Again, I know engine theory pretty well, but never dealt with these. Thanks a lot.
