99 grand marquis , when hot will not start have to let it cool down. In the am when its really cold no start. Battery is new, Checked voltage at alternater it is putting out OK.
Could it be the crank sensor?? Help!

Have you checked for any codes?

I would focus on the Crankshaft Position Sensor and the ECT Sensor.

Thanks TGM, She took it in and they could not pull any codes. I will check it out the sensors!

Okay, She didn't tell me everything. It's a 2003 grand marquis v8. Won't start when cold or hot. It also sometimes sputters and you have to keep on the gas to keep it running,
Fuel filter ? Fuel pump? Etc?cps??

Also check engine light comes on and battery
She took it and found no codes
