Will,
Thanks alot for applying LOGIC to my problem!! I mean, who would use that
??!! Not me, that's for sure... ;-}
Yours is an interesting idea and easily checked. Wes I. outlines the steps
to test for fuel flow in his SPICA booklet which I've done in the past.
I've got a fuel pressure gauge setup to measure pressure between the
pressure sensor and the FI pump. And the inlet opening is only 1/8" in
diameter - easily clogged but would have to come from someplace in the fuel
circuit between the front filter and the pump...leaves just the filter
element or a piece of fuel line came off.
On the electrical side, I measured the voltage at the coil on the wire
(green-black) from the ignition switch. It should be 12v but I got readings
all over the dial from 12v to 7v. I'll test this one by putting on a jumper
wire from the battery to the coil and see if it stays running longer than 45
seconds or so.
Thanks,
Bruce
