1997 V70 XC Hard Cold Start

I am sorry, I misphrased my sentence.

It should read:
- If you jump the 15-87 and car runs, fuel relay is bad.
- If you jump the 15-87 and car does not run, fuel pump (or wiring to fuel pump) is bad.

Sorry for the confusion!

Re Fuel Pump RELAY, you have 2 options:

1. New relay from dealer is about $50 or so.

2. Repair the relay using cheap capacitors ($2-3 from Radio Shack).
Search for the DIY by "Ozark Lee".

I did read that very cool stuff, I will be doing the radio shack upgrade on a few relays

I am next changing the starter relay. The way I found to make it start in the meantime was to get a small code reader/eraser and use it when it does not start. After reading and erasing codes, it starts right away, no matter the cold weather. I'll keep you posted about the starter relay. I'll change it this week.

It sounds like having the key in the On position for a couple of minutes for the code reader/eraser may have done something to enable starting. I'll try that.

My 1999 XC's symptoms are as described by others. When it does eventually start, there's an audible buzzing (fuel relay?) until the engine warms up a bit.
