Hi there. If this started right after these parts were replaced then it may be a defective crank sensor, but I would definitely look at the work that was done to replace the heater core. It is possible that something was disconnected or pinched when the work was done causing an electrical issue.

I usually install a scan tool to see if the computer is powering up and then test for power at the fuse box and from the ignition switch. It can be the crank sensor as that is a common failure on this vehicle. It concerns me the most that this occurred right after the heater core was installed as there are plenty of circuits that could have been affected during the install.

If you need to have this crank no start condition checked, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this problem.
