After installing the new engine, it wouldn't and still wont start with the brn/blk timing wire connected. Actually it starts now but Pulsates and Pops. Up and down during idle. If i give it any gas it pops. Someone said it was the stator. Another said it was the prom, yet another said to get a new distributor and another said the was the ECM. I've replaced the ECM, ESC module, MAF power burnoff module. Had it silly scoped (sp)????
NOTE: '87305 TPI, ECM on GM HP 350 HO 330.
