Ok folks I need some help. If some of you have read my other posts you know I have been battling a cold start issue for the past several weeks. Here is what the car is doing:
Won't start on cold days after sitting for a couple of hours. I have to turn the key on and off and crank the car three or four times unitl I hear the fuel pump kick on and pressurize the line at which point the car starts fine and runs fine no problems.
Here is what I have done:
1) Replaced fuel filter.
2) Replaced Coolant temp sensor (car defaults to warm start if bad).
3) On to the fuel pump...
I am now to the fuel pump:
I pulled the back seat up to find two fuel pumps? Is this correct? I checked both for Voltage and they are both at 12v's. When I turn the key only the passenger side makes any noise. Is this correct? or should both sides make some noise? Does anyone have a wiring diagram for the fuel system? Also I believe this is more a matter of pressure leakdown rather than fuel pump. There is a diaphragm in the fuel line before it hits the fuel rail (round metal part splitting the fuel line, not the connector). Has anyone ever heard of this going bad?
