Hello. If the vehicle is not starting after the timing belt was replaced, then the compression needs to be checked as the timing may still be off. If the compression is fine, then the crank sensor may not be installed correctly or it may be defective. I usually install my scan tool to monitor its reading to see if it is working correctly. If it is, then further testing will need to be done as it may have another sensor failure or possibly a fuel system issue. If you need to have this no-start issue diagnosed, consider YourMechanic, as a certified mechanic can come to your home or office to have this resolved.
