KA24E Pistons 1 & 2 will not combust

[noiz3]

hi, i have a KA24E and the pistons wont combust. i have checked the fuel injectors(replaced all o-rings and what not), i checked comprsion and the sparkplugs and sparkplug wires, also i check the distributor and everything around it on in it. i have no idea what is going on, my dad builds cars he has no idea what is going on.

please tell me what this problem is

your pistons may be seized up.remove the spark plugs and turn the crank shaft pully and see if the pistons move.If they do move make sure your getting spark from your coil. Remove the coil wire from the center of your distributor and pull the rubber back and touch the end to a ground and see if it sparks.

My 3rd and 4th wouldnt fire on my KAE i replaced the coil, new spark plugs and wires, timed the distributor and new injectors and she runs strong now.
