ba10 to ax15 swap problem-engine wont stay running-stops abruptly

i am doing a ba10 to ax15 swap. when i turned the key for the first time, it would only crank once or twice. i figured that the battery was dead from sitting for awhile, so i bought a new one. after i put the new one in- i got it to crank over enough to start it, but that was after about two minutes of intermittent attempts. right after i got it to start, it would immediately die. i got it to start again and tried to rev it up a couple of times, but the second i let my foot off the gas it would die again. the strangest part is that it isnt shutting off like an engine normally would - in a smooth manner. its an abrupt stop, as if something is binding up. this happens whether i have the clutch in or not. the ax15 came out of a 93. i bought a new internal slave and master for the 93 and bled the system properly. any ideas?

I would probably pull all the spark plugs out & try turning the engine over manually, with a ratchet & socket on the crank pulley. If it's really difficult to do (with the plugs out) I would think that something is binding up, as you mentioned.

There is no situation that cannot be improved with a small but well-placed explosive.
