Hi guys, I'm new to these forum's and dont really have a 318ti, I actualy have a 1995 320i with EWSII. So sorry if I'm being rude jumping in your forum to ask for help, But I would really appreciate the help with my engine swap trouble. I got my hands on a auto 1993 m50b25 non EWS engine with 211,000kms as my auto 1995 EWSII m50b20 with 165,000kms was completely dieing

it had the works that needed replaceing but was still running, so I decided that the engine was just not worth fixing and I would swap it out. Alrighty the problem's are... Now the new engine is in and everything has been connected, the mechanic turned it on and WhOOPie! it started first time!. Then he turned it off...and it never started again. And now everytime we try to turn it on, it will crank but there is no spark and then it floods the engine. We tested everything and everthing is fine(We havent swaped the ecu yet to check if that is the cause thou) The engine swap consisted of the m50b25 engine/the m50b25 wireing harness from the non ews engine/a 413 Red lable DME(ecu) and the O2 sensor needed replacing from siemiens to bosch for the 2.5 engine. Everything else from the 320i has remained the same like...tranmission/gearbox/exhaust(the manifold is from the m50b25 thou) and everything else etc that came with the 320i Note* both cars did not have ASC all the pump's and everything is new in the engine as I had it rebuilt. I hope this is enough information to deduce my problem and if you could help me out with how to fix this. Thank you for taking the time to read this.
