I changed the fuse for the fuel pump on my 84 volvo 244 GL and now it won't start! I can't find the reset switch or button, and I have to go to work in the morning. Please help?

 

Did you move the fuse around while trying to start it?

 

Yes I tried adjusting the fuse to make sure it was in properly.

 

I know one time she didn't start and I just spun the fuse around and made contact and started right up. Why did you change the fuse? Is it the right amperage?

 

Does the pump make a whirring noise before you start the car?

 

There are two fuel pump fuses also, so I imagine you replaced fuse number 7 correct? Anyways, I would just remove the negative battery cable to reset the system, not sure about that reset button you are looking for.

 

I hear no whirring nouse, I replaced the 5 and 7 fuses with the correct amperage for no reason. The other fuses just looked a little old and so I wanted to replace them with brand new ones, and suddenly the car wont start up. My 1992 740 had a fuel pump reset button in the trunk right behind where I put fuel in at a gas station. I looked in the same spot on this one, and it's not there. I'll try disconnecting the battery now, but in my experience when the fuel pump needs to be reset, nothing but that button will turn it on again.

 

If you hear no pump noise, or a click from the dash, I would say your fuel pump relay might be the culprit.

 

I read that the fuel pump relay is under the glove box on the passenger side. I looked under there, see some wires and a box, not sure what exactly is the relay but everything seems to be in order.

 

FP Relays look like this thing 1981-1985 Volvo 240 Turbo Fuel Pump Relay
(this may or may not be the exact one)

 

Thanks for the link. So are you guys thinking I may have blown the relay by putting a new fuse in somehow?? Or that I need to just take it out and put it back in to reset the fuel pump?

Is there no fuel pump reset button on these cars? This would be the first one I've ever owned without this button.

 

No, it should have just worked. No pump noise to me indicates you are not getting power to the pump by either a bad relay, or a really corroded fuse holder.

 

Well I missed one day of work but got my car towed to a mechanic for free (thanks AAA) and then the mechanic fixed it.. for free. They didn't say what the problem was, but if they fixed it in 5 minutes free of charge, it must have been something stupid and simple. I'll probably visit them again to ask what the problem was because I'm very curious.

 

Many of the problems on this forum turn out to be some simple wire that was disconnected, or that they forgot to plug back in, which is good and why you should never just start buying parts blindly. These little bumps along the road are all part of the fun so you will be better prepared next time and not miss a day of work .

 

Having been a Volvo 244 GLT owner for 28 years (just sold the car), I'm pretty sure the root of the problem as well as the solution to the problem lies within the fuse-box. The fuse-box on a 240 is a "weak point" of these fine cars - the fuses are prone to corrosion and mechanical fatigue
The fuel pump draws quite a bit of power. Bad contact at the fuse will create an arc and quite often escalates into a surprisingly effective isolation layer...that persists even if you rotate the fuse in place.
Disconnecting the battery and then cleaning all the fuse-holders with fine emery-cloth, sand paper or steel-wool (make sure no strands of steel short-circuit the fuse-box) and a dash of electric cleaning fluid + a set of new fuses will be a good idea.
But as always - messing with something that works may lead to it not working anymore...
