Tried starting the GTA yesterday morning. Fires right off when first turning key, then nothing. Engine will turn over as long as I turn the ignition key with no start after that. Come back 10 minutes later, turn key and fires off then nothing again. Hooked up battery charger after running battery down and it did this all day long.

Things I checked;

Fuel releases at Schrader valve on rail. Also hear fuel pump engage when key is turned on

12 volts on coil wire post with ignition switch on.

Out of ideas here. Any suggestions will be appreciated.
