fuel issue

[Peter J Larsen]

could not get my white Innocenti to fire - up. ( it turned over very well)
Checked the spark ok
undit the fueline to the carb and checked for fuel( dry)
turned ignition on no click from juelpump and no fuel showed up
tapped lightythe fuel-pump no fuel was pumped.
Any other ideas, other then ordering the new fuelpump/??
The pump is in the car. since april 2003
thanks for input.

Check for power to the pump.

Is it fused?

[mascher]

A fuse or a connection or both. If it was a fuse something else would have failed since the fuses are usually shared, still worth a look because it's easy.

If I recall correctly, the only connection other than the fuse block end and the fuel pump end, is tucked away above the wiper motor. This is the group of connections from the main loom to the rear loom.

The fuel pump wire is white in color, at the connection Kelley mentioned, on both my '63 & '69. Don

Remember it's an inno.....completly different wire harness. Peter if you cant find the problem...i'll find it when i get back.

[Peter J Larsen]

thanks for all the input.
Yes the inno harness lays out different.and this was rewired i think in germany too so....
The fuelpump is not secured by the fuses
I checked. The wire from the pump might
go direct to the ignition I will check and go under the car. and trace it.
Yes james when you are back sounds good
if i dont find it.

Start easy. Look for power at the output side of the fuel gauge.

[Dixminion]

A fuel guage has an "output side"? Is the "input side" a portion of ground from the tank sender? Are we looking for 12V (10V) on the side of the guage opposite the sender wire?

Did the Inno originally have a mechanical fuel pump? If an electric pump was added later an installer might power it via the ignition coil + terminal.

fuel issue

I checked the ground connection at the pump it is clean now.
and checked fuel goes into the pump.
I traced the wire from fuelpump to the engine bay comes out on the left
side where the fuse box is colour is grey and it goes to another
5 piece connector sort off. power is there too.
Still no gas to the car.
Thats all i can do. I wait when when james is back he perhaps can sort it out.
thks,. for all help.

[Peter J Larsen]

Inno is running now.
There is a fuse - inline- not in the fuse box. blown fuse, because fuelpump de-
fective points are toast, frozen.
thanks james.
Question i have already 2 defective fuelpums
a new fuelpump SU is 15o. $ is there any
way we can rebuilt those?? at what costs?

[mascher]

Burlen Fuel Systems sells electronic rebuild kits and point sets for most of their fuel pumps. Keep in mind too, that $150 isn't a lot of money for a fuel pump that often lasts for 20 to 30 years.

This one lasted 6 if I remember right.

fuelpump

yes, on my white inno it took 6 year to go out.
on my green inno only 4 years.
maybe I should look for an all italian fuelpump perhaps!!!!
