I have a 93 ford thunderbird 5.0 and i have to crank it for a few seconds to start it at all times but when its very cold it dies sometimes and the second time i crank it it fires right up and fuel pump is making noise at all times as well other than that it runs perfectly no hesitation and plenty of power also idles smooth is this the start of a major problem replies appreciated thank you.

I would check pressure in the fuel rail. Perhaps the fuel pressure regulator is bleeding off. Also perhaps the rail is not being primed when you turn the key to "ON", before you crank. This would be a relay problem.

Thank you, but do you mean the fuel pump relay or a diffren't one also what about the fuel pump noise its working but is very annoying and i don't know how to test the fuel pressure ty again.

Listen very carefully for the noise when you turn the key to the on position do not start the engine if you hear the noise then its probably the pump.It will run for a few seconds when you turn the key on if not I think you may have a vacuum hose leak.

Yes you need a gauge and a T fitting to test pressure in the fuel rail. Also there is a fuel pressure regulator that might be leaking. What I'm driving at is that at night the fuel pressure may bleed off in your system so that the fuel pump has to prime the entire system before the car can start.

OK but I have to crank it for a few seconds every time i start it not just in the morning, and what relay did you mean is there more than one for the fuel system thanks for your help.

I couldn't say without looking at the workshop manual for your particular car, sorry. Strangely enough, there is remarkably little standardization among automakers. But it would be good to check the fuel rail pressure before you go barking up the wrong tree.
