Re: 99 dodge intrepid fuel pump low voltage

I cant figure out why a shop wouldnt check voltage and amperage during
a fuel pump diagnosis. Did you pay them to replace the pump or to
diagnose the problem? If they were paid to diagnose the problem then
you shouldnt have to pay parts and labor on the pump.
Anyhow...
So, you've got 8.5 volts @ the pump.
The next thing to check is the voltage input and output at the relay.
You should have battery voltage to the relay with the key on.If you
have battery voltage out of the relay *when cranking*, there is a bad
wire or connector between the relay and the pump. I see this quite
often.
Good luck,

Hello,
I have a 1999 Dodge Intrepid that has a 2.7 engine that quit running.
I could not hear the fuel pump cycling when you turn the key on and
the car would not start. I played with the key off and on for several
times and then the pump would cycle and I tried to start it and it
started ok and ran fine. I test drove the car for 10 mins. and then
shut off the car and it would not cycle again or start so I assumed
the fuel pump went out. I tried switching the fuel pump relay with
another relay of the same part number but still no cycle. I had the
car towed to a repair shop and they checked the fuel pump wiring with
a test light and it had power at the connection so they proceeded to
install the new fuel pump but still the same problem. After they found
out the new pump did not work, they checked the voltage and found out
there was only 8.5 volts going to the pump. They said they checked all
the grounds before they discovered the low voltage. Is there any
sensors that would cause the voltage to be reduced? The car over
heated a week before because it was stuck in traffic and the outside
temp was close to 100 degree's that day but shut it down as soon and
the hot like came on. The car also has a remote control starter on it
and they are going to check that part out tomorrow but I don't want to
pay for all the wasted labor hours if there is a common problem with
this year and model. Any help would be greatly appreciated. Email is

Thank you

On other thing that just hit me was that the relay is not cycling now.
Is there two separate power lines running to the pump? I think they
told me that one of the lines had a full 12 volts but the other only
had 8.5. How is the pump getting 8.5 volts if the relay is not
cycling?
