im stumped!

after installing CP 9:1 pistons, eagle rods, acl rings, new head gasket, 92 integra head...my car wont start. (check my sig for all the specs) I turn the key and i hear my fuel pump prime, turn a little more and it cranks but wont fire up.

i have compression 150-150-150-150 (remember i have low compression pistons)
i have spark
i have fuel to the rail

is it possible to have NOT ENOUGH spark? could u have spark and still not fire up? ive checked everything...im puzzled?! im in the process of getitng a fuel pressure gauge but until then what would be the culprit? the only thing i havent checked are my fuses but which ones would i check?

After cranking for a little while, pull the spark plugs & see if they're wet with fuel. Just 'cause you have fuel in the rail doesn't mean the injectors are firing...

I agree. You may have fuel in your rail, but the injectors might not be working for some reason. Did you make any changes to your fuel system, maybe injectors because you are going F/I?

i suspected that but the likely chance of all the injectors going bad at the same time? i will check though.

anybody else?

Get the fuel pressure gauge. Someone recently had a problem like yours, turns out there wasn't enough fuel pressure, the pump was shot.
Also check the firing order of the plugs/wires, if it is incorrect, it will not start.
