Run of Good Luck Comes to an end...

I've had a good run of no problems with the Spider...it's been 3 years since my last real mechanical issue. That all came to an end on Saturday.

Was on my way home from church, turned a corner and she just died. Pulled onto the shoulder and turned the key. Cranks...but what don't my ears hear, but the familiar hum of the fuel pump (remember she's F/I). Checked the combined relay, and it clicks with the key. So looks like either a wiring problem between it and the airflow meter or the pump died. Hope it's the pump...got one on the shelf to replace it, and that's a whole lot easier than finding a wiring issue.
 
Hi Guy, It's good to see you're still kickin'. Don't forget the "nerf" switch AKA inertia switch. I can't remember if it grounds or opens a circuit, but it can shut you down, without actually being tripped. Don't panic, 35 year old stuff can screw up, but not be fatal. It might just be a corroded connector thing. Good Luck
 
Fairly easy problems to fix. :yesnod:

Thank the Triumph gods that it isn't serious, fix it, and <span style="text-decoration: underline">drive!</span> :driving:
 
Update...the plot thickens. No power at the pump. Had a spare combined relay so swapped that. Still no power. Pulled the inertia switch. That tested OK. Checked the wires to it. The center one has power when the starter is working. So...looks like it's a wiring issue between the inertia switch and the pump, as the wiring diagram shows the switch is the first thing "upstream" from the pump.

Just a thought, before you go hunting through the wiring: have you tried actually putting a load on the wire & inertia switch? Sometimes a connection can be marginal enough that it will pass enough current to drive a voltmeter or test lamp; but not enough to run something like a motor-driven pump.

I happened to notice a "telephone toner" type tester in HF the other day. Haven't tried one on a car (mine went AWOL years ago) but it should help for chasing down an open wire.

The little box with the clip leads generates a tone that can be heard through the speaker gizmo any time it's tip is within 1/2" or so of a wire connected to the tone generator. So you hook the generator to one end of the wire and then go tracing along the harness looking for where the tone disappears.
