i have a 2000 civic si....
engine: b18c1 block
b16a2 head
b16 tranny...
it will not start...no noise except from starter....it has been dead for 1 week already...it's been breaking down since the rebuild....i know that its eletrical problem.....but dont know where...because sometimes the AC just comes on by itself......the timing is always jumpiing even though i set it perfectly w/ timing gun....it's been working but V-TEC sometimes stop working n sometimes WORK and kick in very hard n loud.....but sometimes choke in gear and shut off automaticially......WHEN the engine starts its normal with no idle and smoke....its very queit like a new motor.....but now it wont start cause the other day i put the battery in the wrong way cause it was dark and my brother took my battery and left me a different one.....so i think i burn something but i checked all the fuses and all the relay including the main relay and bought a new one....changed ecu and changed all the sensor.....CAN U GUYS HELP ME OUT ....I NEED IT FIX ASAP......THANKS
