I recently bought a '90 crx si with a dohc zc swapped into it from previous owner. I have only had it since Aug, 13 2009 and have not driven it much at all. This morning i went to start it and it would not fire up (cranks fine). I had noticed early on when i had first bought the car that it would stumble upon start ups (when cold). What i mean by stumble is it would start, but feel/sound as if it was only running on 2 or 3 cylinders. After about 10 seconds, the stumble would go away and it would run just fine.. I thought i would check the spark plugs and wires for a starting point in troubleshooting the problem since i had imagined it was missing. I started by taking the plug wires off and it turned out they were so corroded they broke off at the ends. After taking the wires off i removed the spark plugs and noticed they were gapped way out of wack (.40, .35, .00, .45) I immediatly went to the parts store to pick up a new set of plugs and wires.

Having put on correctly gapped spark plugs and a fresh set of wires, i tried my luck once more to see if it would start.. no luck It cranks just fine and pops throughout the process..

Any advice and inputs welcome.

Thanks!!

 

***SIDE NOTE***

The car cranks at full potential and is NOT throwing out any codes or check engine light. It has both, spark and compression (Have not yet checked fuel, and NO.. It is not outa gas. lol).
