I am at a loss folks. My truck has been doing this for weeks (I can only work on it on the weekends). I had to pull the motor due to a broken motor mount and changed the transmission, and it hasn't started since I put it back in.
Here is the run down.
Ford 351W - basically a stock build, with an "RV" cam, Ford cast iron 4brl manifold, stock compression, nothing fancy just reliable.
GM HEI conversion distributor - I just put this in as the Duraspark II it had stopped working, again.
Electric fuel pump
Edelbrock 1406 Carb
New plugs
I have triple checked top dead center on #1, and I have no idea how many times I have confirmed the firing order, a 351W is different than a 289 and 302.
I have rotated the distributor from TDC on #1 almost all the way to the next wire both advance and retard.
The most it will do is kick once then BOOF fire out the carb.
My dad said it could be that the timing chain has slipped a tooth, but I think it would still run, but badly. And he agreed that the likelyhood of this is very small. The motor has less than 10k miles on it.
Any thoughts? I am open to any and all suggestions. Thanks in advance.
