Don't spend anymore money on parts that may not need replaced. If the check engine light is on, scan it and post the code numbers here.

If there is a part to replace is your Automatic Shut Down relay. You may replace that. Then perform this daignostic.

NO START OR HARD START

Ensure battery is fully charged.
Check spark plugs.
Perform spark test.
Check for sufficient fuel and fuel contamination.
Check fuses.
Ensure ignition timing and fuel pressure are correct.
Check fuel injectors.
Check crank and cam sensors.
Ensure timing belt or chain has not jumped.
Ensure ignition coil resistance is correct.
Ensure rotor, distributor and plug wires are okay.
Check coolant temperature sensor and connector.
Check TP sensor and connector.
Check airflow sensor.
Check anti-theft system (if applicable).
Check for contaminated fuel.
Check for vacuum leaks.
Ensure fuel pressure is correct.

ASD relay is inside the Power Distribution Center (Fuse/Relay Box) under the hood.

All right. So far so good.

You did mention that you had the check engine light on. Please post the code NUMBER(S), not description.

I understand that. While most consumers will readily hand out their hard-earned cash, as a tech, I prefer to follow the proper diagnostic procedure for codes.
