Dear 91 legend fans and experts,
I have read all the threads about this common problem but I am still puzzled by my baby's behavior. I narrowed down my problem to be correlated with the fuel pump whenever the car doesn't start. But what drives me nuts is that sometimes it starts and sometimes it doesn't. This happened when it is cold (45-55 F). It happened at the start of the day, the middle of the day and at the end of the day. What drives me even crazier is that when I jump it, it starts. I just bought a brand new battery from the dealer as I initially thought it to be the problem. I have desoldered and soldered my main relay. It is starting fine now but I am afraid of it not starting on me again. Moreover, whenever she refuses to start, I still hear one click by the main relay (even before the soldering) but cannot hear the fuel pump.
My questions are:
1- why does the car start when jumped if the problem is fuel-pump related?
2- Can the malfunctioning of the fuel pump be a sign it is going bad?
3- I am wondering if my soldering was even necessary as the main relay used to click when the car didn't start, was it? Does clicking mean that the relay is fine? Or can it be clicking while not delivering the required voltage to the pump?
4- If she does it again and doesn't start, what should my next step be? (new fuel pump
Thanks kindly for all the help in advance and may this forum thrive and be blessed forever.
