Stranded on the Telegraph Track. 100 series cruiser.

yea Davoe it is a standard NA 1hz (98 GXL) with aftermarket turbo fitted. This was the first time I have been let down by electronics in nearly 30 years of cape trips. Mostly in 60 series but also a variety of other vehicles. Only had this one for 10 months and apart from this problem was very happy with vehicle. But it was a serious problem and we were lucky help turned up. I will not be satisfied until the problem is sorted. An auto elec up here said all I can do now is to keep driving around and wait until it stops again and phone him and he will come and sort out where the short is there and then.
Not a very ideal solution!

Sounds very much like a broken wire to the fuel cut off solenoid.
Apart from the glow plug timer there are no electronic gizmo's on the na 1hz.
Unless it was fitted with an aftermarket immobiliser.

My 99 1hz has a mechanical fuel pump that sucks directly from the fuel tanks...however there is a solenoid that seperates the two tanks, I have known this to give trouble in some vehicles...I thought if it happened to me, I should be able to plumb it to bypass the solenoid until it was fixed or carry a spare...Phil

Phil, that's exactly what my 1hz has and that is why I could not understand the reference to the electric fuel pump. As mentioned in the previous posts, the only possibilities electrically would be the Solenoid that controls the two tanks, if in fact the vehicle has dual tanks, the fuel cut off Solenoid or the immobiliser which I understand some 100 Series have. There is nothing else in the 1hz that is electric and that is why I have a 1hz.

Dick(Int) there is a solonoid on the mech fuel pump that shuts off the fuel to the pump - this is how they shutoff by key. fairly common problem for this system to crap itself

I agree with everybody else, the only electrics are the fuel shut off solenoid or the dual tank solenoid, like others this is why I like the 1hz, very simple system,I certainly didn't buy it for the power.

Davoe, I know you spend a lot of time with the 1Hz so tell us, how frequently does this solenoid fail. So far I have never had a problem but would like to know in advance what to expect. Is it held open by power so that any loss of power cuts off the fuel? What is the recovery plan if it fails and you are stranded. The old mechanical cut off cable had a lot of advantages.

mostly mine vehicles so you dont really care what the cause is you just take it to the w shop.
it doesnt seem the solonoid fails but rather the power wire most likely due to corrosian and vibration.
Fix i guess is to run power straight from the battery to the solonoid which should get you out of trouble. On newer 1hz the fuel pump has extra gizmos atached to it so you would need to get someone to point out whih is the solonoid wire

Davoe that is how we fixed the problem. Cut into the two power lines that go into the fuel pump solenoid, joined them and ran a wire straight to the battery as it kept blowing an ignition fuse located in the front passenger kick panel.
They couldn't find the short in Bamaga and repaired the wires. When we set off home an hour out of Bamaga a fuse blew again. This time we knew straight away about the location of the fuse panel inside the kick panel and I replaced the fuse with a 20amp. It got me all the way home without having to hot wire like we did the first time.

I just wish there was a simple way of finding the short.

How ya goin Trevor,
That fualt was found to be computer issue, donor computer was sourced and away it went.
