I just installed a b20 in my gsr and it wont start. When I try to start it it makes a popping noise and shoots a blue flame out of the manifold (where the egr hose would connect). I know I have spark and fuel pressure. I think my vacuum is good, it should atleast be enough to turn over. I also had this same exact problem when I installed a b18 in the car a couple months ago. I thought the timing was the issue so I switched motors. Now im having the same problem. Ive also checked my grounds a million times and added extra ground wire but still nothing. Any ideas?

It's wiring then, if you used the same engine harness, then junk it... Or I'd check CYP Circut in that harness, for some reason the dizzy if firing out of order...

BUT for good measures also Check and double check the timing, including the firing order on the plug wires, and the order on the injector wires..

Or the timing belt. It could be off a tooth.

Sounds like welds on your manifold blew

i dont see any cracks on the manifold. where specifically would i look for a blown weld? and how would that happen?

also the firing order has been 1-3-4-2 the whole time
