mexi-beetle intermittent starter problems

I have a 2003 mexi that intermittently won't start. I turn the key and
the fuel pump starts, but no click of the soleniod or turn from the
starter. Eventually this goes away and it works for a couple weeks,
then problems again. Any ideas?

First check the push-on connector at the solenoid
for looseness/corrosion.

The fuel pump gets a signal from the "Start" position,
so I'm thinking the Ign sw is OK.

Post back if you don't find anything and we'll
see about more detective steps.

Verified no voltage on the solenoid wire when key is turned. Could it
be a bad relay or something?

Good test!!

I'm not familiar with the wiring scheme in the Mexi;
earlier FI cars fed the solenoid direct from Ign sw
and used the "Double Relay" to control the fuel pump.
Maybe they swapped around?

Follow that solenoid wire (under back seat) and see
where it leads.

Mexi beetles should have a modern ECU and a conventional relay for
fuel pump.
