C4 won't start

'93 car was idle for two years. Supposedly had new opti.I changed the fuel pump the car started right away a little rough but ran.I did this for several days now car won't start but turns over. During this the engine wants to turn in reverse after about 20 secondds of cranking and some backfire through the intake. Also, when the engine ran there seemed to be a miss on the passengers bank. When the car was put in drive engine was extremely rough acted like running on 4 cyls.

Additionally, the only codes I get are c12 although once has h311,h33,h35,h37. I imagine with the battery out all the previous codes have been erased.

Can anyone help to determine the starting problem? thx chip
