#1 cylinder not firing
Posted: Sat Jun 04, 2011 6:03 pm
hello, im back again!
i finally have the l28e powered 77 280z running but it has been sounding like its missing on a cylinder or two. upon further investigation i have found that #1 cylinder has not been firing. its really wierd because i have good spark and fuel injector is also good. i tested it before i replaced the one that i thought was frozen. if i have good spark and fuel then why dont i have combustion? the engine is rebuilt and has not even been broken in yet. i have not tested that cylinder for good compression (i dont have a compression tester) but on the compression stroke with the plug removed i get a big whoosh of air. i put an led to the pigtail and also can confirm that its getting a pulse. d'oh!?
