the old engine has this DR6200 sensor down near the crankshaft pully, but the new engine doesnt have it, and the old one will not fit in the spot, the hole on the new engine is egg shaped while the sensor is round entirely


is this the reason why my car wont start? I fixed the low battery and the connection to the starter, but it just cranks and cranks without anything else now, even with starter fluid,


another thing, I have two coils, one with two plugs on it, and the other with one of those plugs blocked out and somehow I have only one igniter between the two, this new engine is supposed to be the EXACT same, 1995 Chevy S10 Blazer 4X4 auto 4.3

someone make sense of all this PLEASE, I have put so many hours into this swap and I just want it to start

 

any answers on this?

 

There were a few different configurations for '95. Not all of them used a CKP sensor.

Basically, you need the proper timing cover and need to ensure that the reluctor ring on the crank is the same as what was on your old motor.

Sucks, but it would have paid to compare everything while both engines were out and side by side.
