Hey guys,

i recently installed my new longblock and when i went to crank it the engine turned over fine but i had weak spark and would not start. There's good fuel pressure. I checked all the grounds and they are good so i tested the ignition coil and found that the primary resistance was good but secondary was bad, so i will be picking up a new one from advance in the morning. Hopefully this solves my problems so i can get my DD back on the road. If yall know of anything else to test/check please let me know.

thanks as always,

Kyle

I'm also having this problem too so let us know by tomorrow, try to mess around with the timing but no luck, buddy told me maybe something got to do with the choke that I don't know of yet. It have hard time starting when it haven't start for 6 hours or so but when its all warm up it fire at the first crank.

mine has yet to start period. have you checked your cold start injector to make sure its working properly? just an idea, i'll have more info tomorrow with the new coil..

Haven't check it yet but I have a spare one so tomorrow if I can replace it to see if it is the problem. I also try using those premium start-up but it also didn't help at all, and when I spray them in I can see them coming out from the tail pipe so it seem to be un-burn so I'm thinking it also could be the ignition coil. Also when I check the valve spec. on the exhaust side all of them have very tight spec., try with .0007 gap and it didn't even slide in so I think its off by alot, but all my intake valve are within spec. ( driver side head only ), so you think this may be the problem for my starting issue?

i dont know much about valves but if they're not functioning properly that could very well be it. your engine needs 4 things to run, timing, air, fuel and spark. it is just hunting down which of these it is..

well i found the problem. turns out when my dad offered to help me he accidently hurt progress. When he installed the distributor he did so 180* out of TDC so of course the engine isn't gonna start. After a quick process of elimination today i figured thats what was wrong. IT LIVES!

awesome, isn't it the best feeling to solve a problem without having to shell out any $$$?
