Starting problem My wife drove it to the store and said it was fine. Then she tried to start it to come home and it just cranked over and never started. A friend of ours says its probably fuel filter/pump. We removed the fuel line after the pump and get an initial squirt of fuel as the key is turned to on. Then as we crank it over, no more fuel comes out at all? Can you help me please? Is it the pump or could it be anti-theft or start system issue? I don't know :(
