Hello, did you do any basic testing before replacing anything? When the vehicle refuses to start, have a helper crank it while you check for spark at the plugs. If that checks out, use a gage and check fuel pressure. Can you check for troublecodes?

In addition to JDL213, has the check engine light come on? Also, like he said, if there is no spark, there could be a problem with the ignition module.
