Update on Brumby . Has been taken to autosparky diagnosis : ignition module in dizzy and rev sensor both were faulty. He has replaced both , it is now running but feels like on 3 cylinders so now at mechanic to find what this problem is.....

I am satisfied once I get new rev unit car will run . Car is driven By daughter so not to comfortable about trying to bypass sensor after understanding a bit more what it does . Thanks all for suggestions .

Have power at coil ,fuel pump runs with direct power have tried aerostart in carby definitely no spark .Have rung 10 wreckers in WA including 3 so called subi specialist results no brumbies or l series in stock . So now resigned to wait for it to arrive from Japan. Local mech has advised sensor fail...

Not to sure how this works but no fuel pump not even 2 second prime on key on and no spark when cranking .

I can get the fuel pump to run with a jumper across the plug on the sensor and yes reconnected coil very carefully when changed and double checked. From smell emanating from rev unit subi dealer said it cactus .

Part number is written on top of box 22631AA100 [ATTACH]2688[/ATTACH]

Its a little 50mm by 50mm black box that hides on firewall above the fuse box under the dash. Correct about nil stock , At least 2 weeks to come from Japan.

have located and removed revolution unit . It has strong electrical burning smell coming from it. Waiting now to hear from local dealer on if I can get a replacement unit ..

Have tried aerostart definately no spark . have not tried to bypass or direct power fuel pump yet . will give a go go tomorow. I have notice low brake fluid warning has appeared on dash even though it is full. now concerned a dodgy earth point somewhere.

Fuses checked ,fusible links checked and ignition switch checked . from wiring diagram the engine revolution sensor or unit is common for no fuel pump or spark occuring.not to sure how to check it though.

I have a 92 Brumby that cranks ok but wont start. It has no spark and I cant hear the fuel pump start when the key is turned. Have replaced the coil as was leaking oil but this made no difference. So I believe the engine revolution unit has failed. Has anyone bypassed or repaired one of these ??
