If the engines fires and then dies off, I have two suggestions.
1. Check the ground at the thermostat. If it is not secured well, the engine tends to die off after strarting.
2. Check the main relay, it runs the fuel pump and is controlled by the Ignition switch, starter and ECM. If the circuit board of the relay looks like has poor or cracked contact, resolder them.
Check for power output on terminal No 7, Yellow/Green wire, for 2 seconds when ignition switch is turned on and will be continous while cranking.
