could be anything from the air flow meter, to the CAS, to the igniter pack, coils, or spark plugs. if your saying that your fuel pump is priming up then the ecu may be ok. have you had the car running before it went into storage? checked all fuses? the ones in the car and in the engine bay. there are also two green relays behind where the ecu is located, if they aren't switching you wont get power to your injectors and coils.
