OK.. found what I fixed and fixed it properly... bit embarrassed and mad at myself for missing it actually.

I had the car running on gas while I was under the dash bolting the modules back up... (I don't know why I had it running either, but it turns out to be a good thing anyway)

When I pulled the unit down to test it, the first thing I did was get the multimeter out and test for positive and earth and the unit had both.. after much much much searching I put it back together and while I am bolting the module back up, the car stops.. and I can hear a relay clicking on and off repeatedly as I wiggle the module.. tracing it I discover the blade terminal on the fuse block has a dodgy crimp terminal on it... replaced that and the problem went away.

it just happened that when I was testing it with the multimeter, it was pulled tight and was conducting fine, but when loose and under no pressure, it was a broken joint.

replaced and all is good.

embarrassed that it turned out to be something simple, annoyed that I stripped out the whole system for a day to find it when it turns out I could have fixed it just reaching under the dash without undoing anything.. still, a lesson learned and a fair bit about gas systems too.

Just thought I'd show you what I've been working on.

Wife is having another baby.. that makes 3 and we can't fit three kid seats across the back seat of our Hilux so had to find something wider.

A bit of looking around found a 95 EF station wagon, on gas, 109,000km with a blown head gasket and some rust and no rego. Cost was 300.

pulled out the mig, welded up rust, tidied up paintwork and cut and polish, fixed gas as of today, put my old EA ghia's blades on it.

Image

Tidied up very nicely if I do say so myself.

The underfloor gas tank was one of the big selling points as it takes up no cabin room.

Image

This is the engine bay obviously, and you can see the converter which is the only part of the gas system I've had to replace as the old one was manky and corroded.

Image

Cleans up very nicely for a $300 dollar car, and the interior is very tidy too, though as it's just a GLI it isn't very flash. (yet.... the wife has already put her hands up for some power windows.)

Once this is over the pits, I can finially do the engine swap in my car as I've now picked up a heavy duty clutch for the T5 for $200 on ebay.. and that is that is what I've been waiting on.

welcome to what mechanics go through every day, at least you don't have to try and charge someone for all the time you spent and then fixed it with a 20c part

yeah, I used to fit 5 insurance car alarms every day and fix a heap more.... I've had this happen in the past but I thought I was wiser now. :-)

sadly it appears not.

Been a few days since I have had a read of this, glad to read that the issue was found & resolved.

I've resolved a few similar issues with my LPG system in my Eb Ghia. Install fails on part of the installer. I guess this is the fun of the "car game" isn't it?

I have a few more issues to resolve when I get the car back from the panel beaters.

That wagon looks like it cleans up pretty good for the money, good luck on getting it road worthy!

Cheers

Thanks mate,

The car came out like new, I've been stoked by it. Now that the gas is sorted she goes over the pits this week sometime. The lpg tank is off getting re-stamped. I'm glad i am in IT now, i do not miss jamming my butt under dashboards to troubleshoot alarms.

Cool. I'm glad I'm almost out of I.T now... I do some consulting for myself, that's it. Bugger the stress & long hours with lots of unpaid overtime that I was doing!

Cheers

Sounds like you have managed to find one of the few good I.T tech gigs out there!

Is the car still running good after this much time?

Cheers

car runs a treat... though now both my lpg tanks are in getting stamped.. pick them up on friday.

Got them to make a professional version of the copper pipe between the valve and the converter, mine worked and didn't leak, but I didn't trust it.

car should go over the pits early next week.

It was a dodgy blade terminal.. Once I found and replaced that, it has been flawless.

Car went over the pits first time, has done about 20,000km since then as my wifes daily. Runs like a dream.. best 300 bucks I have ever spent. :-)
