Hello all
Boy i got a good one here, this VW Van is in town for a
vacation, the engine will quit, some time run rich beford
it quit and sometime not,if you try to start it the fuel
pump will not come on, but sometime the fuel pump relay
will buzz and when it quit and click the fuel pump will
come on and it will start, but will quit any time, at one
time they was no fire out of the secondary at the coil and
also no fuel pump, the costumer replace the fuel pump
relay, but the same problem, the wiring harness is being
modified at the air flow meter, with the VW modification
wish i diconnect and buy pass to try, no help, when i
didn't have fire at the coil, we don't know if we had 12
volt at terminal 15, the van start right up and didn't do
it again. i have diconnect the frecancy valve but the same
thing happen, i had the engine idle set a little high to
make up to for it but no change, the engine load up
sometime and the RPM will got up and down, i have check all
the ground that i know or can find, today my Tech and the
costumer seem to hear like a spark noise or a rapid
clicking coming from the computer but i can not hear it
even with a statescope,but i can hear a engine miss a mile
away, they say that it go up and down with RPM, this Van is
being to many shop and the Man need to go Home,the O2
sensor was replace a year ago, i Have check all the basic,
connector to air flow and Temp sensor, ground Any help on
that one will be appriciate and i will post a fix, the last
one that i had that was close to that one was a bad ground,
but i have check them and the buzzy fuel pump relay really
get me, the costumer say that all he have to do sometime is
touch anything in the engine compartment and the bussy will
stop and it will start
Thank you in advance all
