Well just finished putting my motor back together, replaced my 853 heads with stock 243 head removed my tv2 cam spec 232/234 .595/.598 112 lsa 26* timing and put the stock cam back in and replaced my bbk intake with a fast 78/78 setup but now it wont start now. Can it be cause it still has the tune from my other setup? I know it wont run good without a tune, but would that be the reason it dont turn on?

 

It ought to at least fart and die.

Fuel pressure = ?
Injector coil activity = ?
Spark = ?

 

can it be a gound?is there a gound on the ds block?
