Hi all,
I'm having a problem with my UC torana hatchback. It has a black 202 EFI from VK (stock).
So the story goes, I got the Torana as a daily driver after selling my VZ SSZ crewman (I work FIFO) don't do too many km's so wanted to get around in style.
Mucking around with this and that over the last 5 months one thing that was not right was the dizzy.
It was at 6 deg advanced at idle (should be 12 for EFI) if you moved it up it would ping (got up to 8 on 98 octane) according to the numbers on the dizzy it was out of a 2.85, went to repco and got a EFI dizzy, it was chinese, worked fine except the advance curve was the same as the one I had (not so happy) so I regrafted the one that came in the car, by filling in the stoppers and got 12 deg at idle and 38 deg all in at 3200 or so rpm. So while I was there I found that the coil was a regulated 9v and it had 12v going to it so I found a 12v coil and changed it over, went for a drive it went good but cut out under full noise then came straight back on, then off, and on then off.
I ran a wire from the battery to the coil and away we went, got home and played with some plugs under the dash and it was working again, no big-e but this is when it all went pear shaped!. The next day seemed fine but that night went to go to the shop and it was cranking over but wouldn't start, took the wife's car and thought have a look tomorrow.
Thinking the dizzy, so went looking and had spark and fuel. I have put a pressure gauge on the fuel line and that was fine. After dizzies in and modules in and out and new coil and module. Reading in here looked at the 12v supply, the new red 12v had been crimped on to the pink resisted wire at the ignition switch with one of those dodgy spade things that had melted. I cut that out and the pink wire from the ignition switch and soldered the new red straight from the ignition switch to the coil.
So the car will start most of the time, run for a while then as it warms up shuts off. Sometimes it will start straight up but sooner or later it won't start, this is over 30 minutes.
Had an electrician look and after looking at everything he was leaning to the module, ran it until it cut out, changed the module and it ran for a while, (electrician left) but still cutting out.
Went looking through all the wiring for an intermittent fault but nothing. So reconditioned bosch dizzy, another computer leads and plugs look good (gap 1.5) am happy with the tacho-relay air meter looks good and the car was running well before this happened. looked at all the efi wiring diagrams cant see anything obvious to me.
It is not missing it just cuts out but still has spark (take the lead off and crank it still sparking) and fuel (when it cuts out the pressure gauge is still up and the tacho relay drops out after the motor cuts out)
I live in Perth Wanneroo area, don't mind coughing up the money to fix it but need to find someone who knows these motors.
Please help the wife is going to cut my things off soon after telling her it was a good idea to have this as a second car!
Thanks Chris
