A thick paper clip should work just fine. Let it cool down with the key off before you grab it to yank out so that you don't burn your fingers. The paper clip will heat up a bit.

I Jumped it with the paper clip, it started smoking... So I got to thinking, what if the issue was corrosion and buildup in the outlet, so I tried putting the Relay back... And it worked! Now, the vehicle is running, so I've got to find another issue to pick on

Perhaps the Head Liner

Hi
this relay repair info is very useful useful for repairing fuel pump relay, i have the same problem with my 93' 850. it dies after running for 15~20 minutes and have to wait for 30 min to restart again. it wasn't like that before i put it away for winter. i will try pulling out the fuel pump relay and replacing caps.

i have couple other problems would be great if you can share some experience.
1) central lock actuator burnt, i changed all actuators and then have the same problem in about a month. i found somewhere it is the central lock relay, would it be some repairable, a bad cap or resister.. the relay would cost over $100- which is not a good option to try. any suggestion would be appreciated

2) smell of fuel in cabin, i saw some bulletin about a recall of the fuel tank gasket, but my mechanic showed me possibly to do with a leaky oily injector. there will be fuel smell if i turn off the fan and set air recirculation on. what would be more common problem ?

many thanks in advance

where is it located on a 2000 V70, I´ve opened the hood, the fuse box, but it is not there!!
help me please!

It's under the fuse box that is located under the hood on the driver's side. Remove the torx screws and you will see it.

Good morning,I have a blown Diode in my main Engine Relay 2/32 in the main fuse box,has any one ever repaired one of these?I need to find details of the Diode Strength(dont know the right term)and the direction it fits in the circuit.any ideas? Thanks

1998 V70 Classic 2.5 20V Auto, Normaly aspirated.

I also have a blown diode on my Fuel Pump Control Relay. Has anyone had any success replacing any of the diodes? The blown diode on mine is the orange one in the center.

I had replaced mine with a KAE relay, it works better now (not stalling), but I am still having periodic starting problems (tapping on the relays usually does the trick). The KAE relay looks quite a bit different inside (i.e. cheaper), ya'll think it is just because it is a lower grade product? I had replaced the Fuel Ignition Relay (Main Relay) with a KAE part, and after 4 starts, the car refused to start. Put the old relay back in, and it started up fine (after tapping the FPC Relay). It definitely seems that the KAE Main Relay isn't good.

The write up was written properly. My concern with upgrading the voltage of the capacitors is the same concern that I have with using higher amperage fuses that suggested by Manufacturer. Has anybody had any issues down the road from modding the fuel relay? Other than my concern, I would definately consider doing this to my FP relay immediately as to avoid having the standard problem that usually stems from these relays.

I found this post over a year ago when my 850 stalled at home and clearly wasn't getting fuel as I attempted to start the car. I pulled the relay, tapped it a few times, put the relay back in the car and it started right up. I ordered a new relay (driving on the old one for 4 more days) and have never looked back. If you think your fuel pump has failed, check your relay! Thanks for the posts.

Shiloh, a capacitor is not a fuse; it is not designed to fail. The voltage rating does not specify its behavior, but only the maximum voltage under which it can be counted on to display its rated capacitance. You just have to be sure the rated voltage is above the voltage it will actually see.
