92 240 with stalling issues

LususNaturel · Post by **LususNaturel** » 14 Jun 2005, 11:09

Hi all. I am posting for a friend. He has a 92 240 DL sedan thats stalling alot.

It doesnt do it everyday but it does at least once every other day. When it dies it takes a few minutes of turning over to start it but it always starts.

He says he has replaced the Suction Pump Filter Sock (whatever that is) the fuel lines from filter to engine, and the fuel filter itself (6 times I am told)

I am wondering what else it could be that is causing this. I have already recommended he check his fuses. Im not all that familiar with Volvos so i figured I ask the experts. Any help would be appreciated.

Thanks in advance,

I have some questions about your fiend's car. You say that he has replace the filter sock in the gas tank (at least once) and the main fuel filter (six times).

First of all, was the filter sock in the tank damaged at all before he replaced it? Did it have any holes in it? If so, he should have replaced both the in-tank fuel pump and the main fuel pump at the same time. You see, the filter sock in the tank is the only protection provided for the two fuel pumps. Any dirt sucked through a holey filter sock will cause irrepairable damage to both fuel pumps. The main fuel filter only protects the fuel system components under the hood and not the fuel pumps.

Did your friend check the in-tank fuel pump fuse in the fuse block? This is fuse number 11 in my 1986 740 GLE. A blown fuse will indicate a bad in-tank pump. Oh by the way, these cars will continue to run, even if the in-tank fuel pump stops working!

A dirty main fuel pump will run and stop intermittantly, causing the problems you have described. I suggest you search this forum for key word "kmaniac" to view my posts on this subject.

Great! Thanks for the info. I will ask him.

Just talked to him and he said the sock was in good condition just a bit dirty. He is going to go ahead and check the fuses and relays like you mentioned.

Thanks again for all the help.
