engine starts to fire and stops dead in its tracks?? firing order?

89supra1990 · 01-14-2011, 10:18 PM

89 supra turbo, 7mgte, i swore i had the firing order right but it sure seems like its not. the engine cranks fine starts to fire and then acts like it fires a cylinder half stroke or something and stops dead in its tracks.

i have the firing order set as....1-5-3-6-2-4 (front to back) and the coils 1-6-3-4-2-5 (left to right)

can anyone help me out? Thanks!

well i saw a post on firing orders were a guy had his set as 1-6-3-4-2-5 and everyone said that it was impossible for the engine to run that way, i set mine as the norm 1-5-3-6-2-4 and it ran but missed terribly, then i set it as 1-6-3-4-2-5 just for giggles and it purred like a kitten compared to what it did, may not be right still but it defiantly ran, but now im not getting any spark at all from two of the three coils..any thoughts on that? or are they just bad most likely ?
