I have my car for over 4 years. It worked perfect and never had a
problem until today.
I parked the car yesterday after short run and today morning I turned
the key on, but it didn't start. The starter works file and I have
ignition on sparks. The problem is mostly related to fuel. I also
checked all fuses.
when I turn the key I don't hear the fuel pump sound. I also opened the
fuel filter near the fuel tank and started. No fuel jump out. The tank
in full. For passing the air care test I added a strong fule system
cleaner that my brother believe may have affect on fuel pump not sure.
What do you think? Does fuel pump suddenly die? Is it enough evidence
for purchasing expensive fuel pump assembly.
Any help or suggestion would be highly appreciated.
If you have a set of prints for the wiring, check to see if the fuel pump is
getting any power. On my nephew's s-10, it was much easier. All I had to
do is splice the wiring harness under the truck where his dogs had chewed it
In the Toyota 4runners, there is a relay module mounted under the fuse box
that had become unplugged on a friend's truck. It happened to be where you
could kick it with your left foot as you get in and out of the vehicle.
The last thought I have is the collision safety switch. It could be that it
has gotten corroded or for some reason it has tripped. Your owner's manual
should show you where that is on the vehicle.
It sounds like a fuel pump, but first you should put a volt meter on the
grey wire going into the fuel pump and look for 12V. If you're getting 12V
on the grey wire (ignition on), then it's the fuel pump. If you don't have
12V on the grey wire when you turn the ignition on then you need to back
track through the wiring diagram to troubleshoot.
Thanks for your replies. My problem is I don't have access to fuel pump
wiring. I went under the car, there was no wire near the thank, just
two set of wire went to each tire break system. I opened fuse box and
checked both side of fuel pump fuse. there was 12 volt. I also opened
the back sets for possible access to fuel pump wiring or at least see
something related, no success. Does anybody know how can I access the
fuel pump and how the find the safety switch and check it
