swaps done, engines in..

i've got gas, spark, and compression.. engine sounds like it's trying so so so hard, but it just wont fire..

i'm unsure about the small vac line connections to the throttle body.. one is on the back of the intake manifold and the other is on the throttle body.. not sure which goes to which one..

but it should still turn over, right ??

any ideas, things to check, things to double check ?

thanks

 

double and triple check your ground connections. 99.9999% of the time its a loose ground.

As for vacuumlines, honestly, it doesnt matter where you hook them to, as long as they have vacuum. you can run every vacuum line off one one port with a bunch of T's on it if you wanted to.

 

example ?

you mean like the ground between the resistor box and where it's mounted ?

 

if your engine is the issue, double check your engine grounds.
