Hi name is***** will be glad to help. Check all fuses and relays, Verify the check engine light cycles with the key on indicating the ECM is communicating with the engine. If not verify ECM power and ground or for a faulty ECM. Also check for engine speed signal from the speed sensor and harness. If the ECM is not seeing RPM wjile cranking the engine will not start or run. Are you getting any fault codes? Let me know
