Boy IT's cold OUTSIDE

[JTM]

So my car starts hard basically, it needs a main fuel relay I've come to the conclusion. But I'm not getting one unless I absolutely need one. My car runs fine and starts every time. But today it didn't start. Well it did start once, and me being who I am I had to turn it off just to see if it would start again. And it didn't. Would the cold weather, like 20 degrees or colder affect the MFR issue. I think it would, but dunno. Thanks.

It's typically heat, not cold, that affects the main relay. I would look elsewhere first.

What could cause this problem?

[victork]

my four door has the same prob. keep me updated i wanna know wassup wit this issue also!

[Aeromech]

do you have a fuel leak?

I had a fuel leak....upper injector o-ring seals and my car was very hesitant to start.

just think...air/fuel/spark

limit these things out and you will find your problem. could be an ignitor or coil or distributor...caps can carbon track and cause hella problems.

I would think it is a spark issue for you though.

check the Voltage on your battery.

As someone has already said, MFR issues are typically hot weather related. When you say it doesn't want to start, does it turn over normally and not crank or does little to nothing happen when you turn the key?

The ignitor or main relay is most likely the issue. I had this happen to me 2 yrs ago, at 155K. But i live in AZ so that could have sped up the aging process a bit. But your problems are most likely related to those two things.

Your vehicle will be hard to start in the cold normally anyway. If you're already having issues with a faulty MFR, the cold won't aggravate that, but the combination of the two will make the vehicle very difficult to start. Think about it: hard starting condition + hard starting condition = really friggin' hard starting condition!
