Hmmm. Sounds like the timing might be off or maybe you messed up the firing order, wires, etc. You sure they are all correct?

[e30newyork]

the timing is good and the firing order is good

[Car Addict]

Are u sure you hooked up the fuel lines correctly/sensors?

Flames out of the exhaust when cranking strongly suggests a cam or ignition timing issue. Recheck the cam timing using the mark on the crank hub, not the mark on the harmonic balancer. And have a second set of eyes verify the ignition wire connections. If those are both good you might have a bad harmonic balancer.

If those are both good you might have a bad harmonic balancer.

Or CPS.

I don't think the CPS will do this. A problem with the CPS is almost certainly going to result in no spark (and no injector firing).
