Why does my Fuel pump stop pumping after 10 seconds
I need help with a fuel pump
cause i cant afford $300 part +
The pump will run and pump fuel
for about 10 seconds at which
time it will still run but but the fuel
will stop flowing and get a bunch
of air from INSIDE the pump and
sit at the exit tube .
Im testing it in a bucket of fuel
now but its acting the same way
as in the tank.
I see no way to get the pump out
of the plastic housing for the
I see no debri , filter is clean and it
starts off fine. Its just when it
gets to that 10 second point the
rpms raise a little, the flow will
slowly pulsate and the line starts
filling with bubbles.
Yes there is plenty of fuel in the
car and bucket. Any ideas???
Yep you need a new fuel pump assembly, there is most likely crud inside the pump housing that get pulled into the internal filter and then it drops off once the pump shuts down only to do it all over again next time.
I'm guessing from your other question, you're an attorney..... This is about the mechanical skill I'd expect from a lawyer.
Most likely the impeller (fan) inside the pump is worn out after 22 years. In the long run it's always cheaper and better to replace the fuel pump module assembly than just the pump. Since you were able to remove the pump assembly for testing, replace it with a new one. Rockauto.com has the whole module assembly for $77.79. Hope that helps! Jim
Thank you Bob. It looks like that might be my next step. Thank you too Jim. I was told they cost about $300. Now that the pump is in I get the ol, now this now that. So when I turn the key, the fuel pump doesnt even prime and the engine turns but still wont start. I get no reading on the code reader, BUT, the dash does say "no bus". This issue didnt exist before so what could have happened to cause this. And as for you Ed, I could do without some old a$$ trying to call me stupid when it comes to cars and although im not a mechanc, i do know the internet is FULL of forums for people trying to fix their cars and are given multiple different answers cause it isnt always cut and dry. So why dont you go do what you seem to REALLY enjoy and have mentioned in my other question, which is bend over and grab your ankles!
You're welcome, glad to help! The first thing I'd do is check your fuses. If the battery was not disconnected when you removed the fuel pump assembly it's very possible that a hot wire touched something metal and blew a fuse. I would also check your battery cable connections, especially the ground or negative connections that attach to the body. Also double check the connection and wiring going to the fuel pump. On an older model it's not uncommon for a bad connection to pop up when you have to move things around to make a repair. Hope that helps! Jim
