I installed a b16 SIR II in my 94 civic last night started it up and it ran perfect. I let it run for awhile, went home came back the next day to intall the last mount(that i didnt have the night before)and to take the A/C out. when i tried starting it it would crank but wouldnt turn over i checked all the ground wires i have spark fuel is fine everything i can think of is perfect but i cant get it to turn over. I think it might be somthing that im just overlooking. Please help.
