2004 Ford Freestar Engine

If your saying, after the vehicle warms up, the starter motor won't even crank, I'd have to check starter motor wiring circuits and have the starter tested.

If it cranks good, but, won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure, if possible. Also, check for fuel injector pulse.

With intermittent issues, have to test when problem is ongoing. Are there any applicable trouble codes. Some of the national brand auto stores will check codes for free, if there are any.

No code after it warms up it won't do anything it's like it's dead

Check the starter wiring circuits. Note the diagram. The red wire is hot all the time. The other wire goes hot with key in the crank position and relay energized. Use a test light.

Also, check voltage circuits at the starter relay, underhood fuse box. Terminal 30 is hot all the time. Terminal 87 goes hot with key in the crank position and wired through the neutral switch. The pcm grounds the relay.
