Yep, you want to open everything up anyway for a good look see.....
1) Free Owners Manual download: https://tinyurl.com/fmsz7hk9
2) Don't store your FJ with E10 fuel https://tinyurl.com/3cjrfct5
3) Replace your old stock rubber brake lines.
4) Important items for the '84-87 FJ's:
Safety wire: https://tinyurl.com/99zp8ufh

Finally. Traced the problem. Broken wire at the igniter/cdi. A few drops of solder and shrinkwrap later, hey presto all working.
Decided to replace the pump already so as soon as the replacement arrives I should be back in business.
Many thanks for the help, especially to Pat Conlon.
If at first you don\'t succeed, maybe parachute jumping isn\'t for you!

Ok, my mistake, sorry.... I have a '84 and '92/93 and the TCI/DCI's were in the same area, so I assumed (incorrectly) that your '90 would follow suit....

Looks like it's under the fairing on the right side..... :Facepalm:

No sweat - that's helpful. Now for a few more bits of plastic to come off!

Found it - and a broken wire! Now fixed. Many thanks for the help.
New pump already ordered so I'll fit that next week when it gets here, and away we go!
