    I have a 1993 ford ranger v6 4x4. I'm having to pull my fuel relay to start it. Once it's started you have to plug the relay back in for it to stay running. I also have another problem. The truck runs great for about the first minute you drive it. After that it's like the motor has the choke on. Once I get in like 3rd or 4th gear and lug it out. It goes away. The problem returns if you sit at an idle for about 10 minuites. ( btw I'm new to the whole forum thing so please bear with me lol ) anything helps.

    I have no idea, but might have one once a few questions are answered. That's a might, this seems to be a very odd problem. Does the pump prime up when you turn the key from the off position to the on position? (Fuel pump runs a few seconds and quits) Or does it run continuously? If it runs continuously, your relay contacts may be stuck, or a wire coming off your relay is shorted to ground somewhere. If that doesn't help at all, check your fuel pressure regulator, if its too high at idle, either your return line is pinched, or fuel pressure regulator is stuck. Another possibility is ruptured fuel pressure regulator diaphram which would pump unmetered gas into the intake possibly making it too rich for starting.
