I finished swapping a whole motor in my 92 Civic SDN. Now the only things I changed were the distributor (b7) and alternator(b7). So my cam timing was not touched. But I got the car cranked a couple times were it would idle between 1,500 and 2,000 rpms surgin up and down . When throttle was given nothing. After awhile i figured out I had the following plugs /sensors wrong (TPS, MAP ,Purge SOLENOID and the little white plug forgot what its called.) BUT BEFORE troubleshooting that i messed around with firing order. THen found out i had it right the first time. So i put the firing order back to the CORRECT placement and now my car wont crank. Motor spins but wont turn over.Sometimes ill get a sputter like its about to crank but no crank. and ill get a backfire from the exhaust.Help how do i get my car started? Starter fluid?

 

I also get a backfire every now and then from the intake manifold

 

up help please
