How do u time a 1996 s10 4.3 vortec - 1999 Chevrolet Blazer

https://www.gmtruckclub.com/threads/96-chevy-5-7-fuel-pressure-issue.1479391/

This thread has a few ideas on what to look for.

In general, a 2001 4.3 Vortec engine should be compatible with a 1996 Chevy vehicle that originally had a 4.3 Vortec engine. However, there may be some differences in wiring and sensors that would need to be addressed during the installation process.
It is recommended that you consult with a certified mechanic or an automotive specialist who can assess the compatibility of the two engines and provide guidance on any modifications or adjustments that may be needed to ensure a successful engine swap. They can also help you with any necessary adjustments to the transmission, exhaust system, and other components that may be affected by the engine swap.

hope this helps this is for the 4.3L vortec

Thats a tough one, the computer problems are huge on swapping the v8 in.. If it was me I would use an older motor that's not running a computer..or a crate motor ...

Yes it will bolt up but NO it won't run . The 96 has a crank sensor hole in the timing cover the 92 does not . The timing covers are not interchangeable (different bolt pattern ) . You would have to change complete wiring harness including computer all the way to the OBD diagnostic port . It will work but a LOT of work .

Untill recently GM didn't change much of anything as far as bolt paterns You could bolt up a 350 from 20 years ago to your transmission and motor mounts. But that is not really what your wanting to do. The question is do you have a "vortec" or is it TBI. The vortec motor says vortec all over it (they were pretty proud of it I guess) The earlier TBI motor, at first glace look just like the old carburetor versions until you take of the air cleaner and find a throttle body instead of a carburetor. The two are not interchangeable as to the electronics, they are way diffract.

mine did the same thing i tried the fuse first and it didnt fix it and it was the relay but try the fuse first

I AM LOOKING AT TIMING ISSUES OR INTAKE MANIFOLD LEAK.OR EGR VALVE STUCK OPEN.
