Customer Question

I'm having problems with my 1996 Volvo 960.
I parked it the other day and then it stopped turning on.
I need to figure out why the fuel pump isn't receiving power.

Starter fluid kicked it on for a couple seconds and then it quit.
I replaced the fuel filter (which didn't seem to have much pressure on the lines)
I then replaced the fuel pump and the fuel pump relay.
I noticed that there wasn't any power getting to the fuel pump
I checked the power going into the socket for the fuel pump relay, and there is no power.
There is also only power to 2 out of the 18 fuses in the engine bay when key is turned once.

Check fuse 11B/5 for power when cranking the engine. Remove the fuel pump relay and check for power on terminals 1 and 2 while cranking. Check for a good ground on terminal 4. With 2 jumper wires, jump power from terminal 1 to terminals 3 and 5. Attempt to start the vehicle. If the vehicle now starts, replace the relay.

Customer: replied 1 year ago.
I checked for power on the fuse while cranking. None.
I checked for power on the relay while cranking (with the relay out). None.
There is just no juice coming through at all.
How do I check for a ground?
Customer: replied 1 year ago.
I did try to jump the relay, but nothing happened.
I did the same with the fuel pump fuse. Nothing as well.
Expert:  C. Walker, Jr. replied 1 year ago.

Replace the fuse.

Customer: replied 1 year ago.
The fuse has already been replaced and I checked the power coming through without the fuse as well and there is no power. No power coming through the fuse or the socket when cranking either.
Expert:  C. Walker, Jr. replied 1 year ago.

There is a relay 2/32 that powers the 11B/5 its a good indication the relay is bad. Find the relay should have power on the white wires coming into the relay.

Customer: replied 1 year ago.
I believe I found the relay.
It's very close to the battery.
I see the set of green and red wires running out,
but I do not see the white wires.
Expert:  C. Walker, Jr. replied 1 year ago.

That is a different relay. Looks like the one in the upper right hand of that diagram. Its in the fuse box check the diagram

Customer: replied 1 year ago.
I just checked the 2/32. That is the Fuel System Relay, C right?
I used a light tester and it showed power coming out of 1 and 2 of the socket.
Expert:  C. Walker, Jr. replied 1 year ago.

Awesome swap out the relay

Customer: replied 1 year ago.
I swapped it out, then tried to start the car, but it's still the same.
Customer: replied 1 year ago.
Does the 2/32 C relay control power for the Fuel Pump Relay inside the car? 11C 2/23.
Expert:  C. Walker, Jr. replied 1 year ago.

This is where you get power to the fuse 11 b 6 so if there is no power that means this relay is not working or the wire from the relay to the fuse is bad.

Customer: replied 1 year ago.
Well I swapped a relay I know works into 2/32 C
So you want me to check the wires going into the bottom of the fuse box?
Expert:  C. Walker, Jr. replied 1 year ago.

If you are not getting any power at that fuse but it will only get power when you are trying to crank the engine and that relay is active.

Customer: replied 1 year ago.
The fuse does not receive power when the engine is cranking.
2/32 C has power, but the fuse does not. I'll try and check the wires. Any tips for checking the wires? and where to look exactly?
Expert:  C. Walker, Jr. replied 1 year ago.

Try running a new wire from the relay to the fuse..

Customer: replied 1 year ago.
you want me to try and jump it from the Relay to the fuse? I don't fully understand
Expert:  C. Walker, Jr. replied 1 year ago.

the relay powers the green red wire going to the fuse. So you run a wire from the terminal that gets hot when relay is engaged to the fuse.

Customer: replied 1 year ago.
do I run the wire to the fuse from 1 or 2 of the Relay socket?
Customer: replied 1 year ago.
I'm running a wire from 2/32 C to 11B 6 is what you're saying
Expert:  C. Walker, Jr. replied 1 year ago.

Ye from the green red wire on that relay to the 11b 6 fuse.

Customer: replied 1 year ago.
If that was supposed to start the car, it didn't work
Expert:  C. Walker, Jr. replied 1 year ago.

If that fuse gets power it should turn on the fuel pump. Did you hear the fuel pump turn on ?

Customer: replied 1 year ago.
What else should I do?
Customer: replied 1 year ago.
Well let me double check that.
Customer: replied 1 year ago.
With the wire bridging between those 2, I had someone turn it on while I had my head in the trunk listening and I couldn't hear it.
Expert:  C. Walker, Jr. replied 1 year ago.

Follow the battery cable until you find the main fuses 11A on the diagram I think one is blown. We have to have a back fuse here somewhere for sure.

Customer: replied 1 year ago.
How exactly do I know if those fuses on 11A are blown/bad? They're a bit bigger than the ones I'm used to dealing with.
Expert:  C. Walker, Jr. replied 1 year ago.

You can use a volt meter and check power on both sides.

Customer: replied 1 year ago.
There's power
Expert:  C. Walker, Jr. replied 1 year ago.

I am at a loss here. I am going to open this up to the other experts. Stand by.

Why did it charge me since it was closed and not resolved?
