Greetings,

I own a 1989 Volvo 244 with an automatic tranny. About a month ago the car began to be hard to start, misfiring and flooding out. Starting issue seems to have been resolved with new rpm sensor. While playing with the car while it was hard starting I found that the car would run without the #4 & #6 fuses (in-tank & Main fuel pump fuses). After the RPM sensor fix it still will run fine without the fuses in the fuse block. I believe that this may be contributing to a cold-start flooding issue. Has anyone run into this fuse weirdness before?

Thanks

 

On the US models fuse 6 wasn't used until the later years, it has the 25A fuse under the hood by the battery instead. Your car will run without the in-tank pump (fuse 4 removed) but the main pump will be doing all the work.
