removed guides, starts fine, wont stay on

[427c]

Im a newby. I have a 95 240sx ka24(de) I did the infamous timing chain guide removal ( top and side guide). zipped it up and my car will start fine. But it wont stay on. I pulled 5 codes p0340, p0115, p1320, p0325, p0110. my scanner wont tell me what p1320 is for. I am certain the timing is good. It starts right up runs fine for 8 seconds then boggles and dies. I checked to make sure all sensors are connected and all my fuses in the engine compartment. Ive been going through it for 2 weeks now. Anybody have any ideas on what it could be? Any input would be greatly appreciated.
