End of my Rope

[TOVARH40]

Hi:
I'm trying to get back to life my dear 1999 Ford Ranger XLT V6 3.0, the original motor died at 318,000 miles. I managed to install a rebuild motor and transmission, All fluids are in but seems something is wrong, the motor turns but doesn't start, what are the steps you recommend I follow, Installing the Cam Sync started all this mess, I was never able to make the new motor run. Any help would be really appreciated
Thanks

Might be a good time for the 50-50 test. Squirt some fuel or starting fluid in the intake and see if it will fire on that. If it does = fuel problem. If not = no spark, troubleshoot ignition and timing.
