Answer 1
Cold start enrichment system needs to be looked into. On cold start up the computer in your car should richen up the injector pulse width and give a richer fuel mixture. A scan tool could be used to look at key engine sensors to see if the computer in your car see an acurate voew of what the ambient outside temperature and coolant temperature, you could see what the fuel trim and O2 sensors are reading to see if the mixture is rich enough to support combustion. Also look for a large vacuum leak that may be leaning out the mixture. There is a company that independent auto repair shops get their information from, this same information is available inexpensively for people that work on their own cars.. The information is year make and model specific, covering repair procedures, torque specifications, fluid capacities and specifications, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online -

Is there a troble code? if so start with that first. I did check the TSB on that car and there are issue with the idle air controll for hard to start or no start, but has I under stand from you after spraying starting fluid in the motor it runs a sec then stall that tells me the fuel pump is down,(not working) the best test is to find the bat wire to the fuel pump and see if you have 12 volts if you do then check the ground side shoule be no voltage if all is good replace the fuel pump, If there is no voltage or lost if ground then you will get into elec diag there is tooo much to explain, and the level of care is high not to burnt up the compute or other thing in the car, you should have a auto repair center fix this, We would be Happy to fix your car four you -
