96 Accent shutting off upon starting up and high pressure line leak

I have a very curious problem with my 96 Accent. Odd times when I try
to start up my car, the car shuts off in mid start-up, then I have to
go pop the hood, rotate the negative terminal on the battery then the
car starts up again. Anyone have any ideas?

Next, I'm looking at doing a fuel line replacement once the weather
gets a bit warmer. Anyone have any advice from their experience? I
don't know exactly where the line is leaking (I've got to drop the
tank to see), but I do know that it's coming from the high pressure
line. If anyone has any suggestions or the such, if you could please
let me know what I'm in for.

 

Ummmmm... why not tighten up that terminal? Battery terminals must be tight
and clean of any corrosion. If you can rotate it, it's not tight enough.
If rotating it makes it start, then you either have corrosion under the
terminal or a bad battery lead.

Find the leak, replace the affected line(s) with appropriately sized brake
line using flare fittings. On the high pressure side you can't use
compression fittings, but on the vent and return you can. You'll want to
replace all of the lines from the tank forward until you get to good solid
factory lines. Usually, you'll find good metal in the area of the driver's
floor pan.
