A car problem...

[MSTRS:Me]

After the last successful start, I thought a trip to the shop for a diagnostic hook-up would be a good thing. Famous last words...
This time, at frequent intervals, the engine died while driving. It'd never done that before. Maybe it is the CAS? Eventually, half a k short of the mechanics, in frustration I walked down and got him to come and tow the car the rest of the way. Got there, talked about what was going on, started the car and...it did and it kept going. Never missed a beat. Bastard thing!!
Left the car with him. He reported back that the computer showed no faults or error codes. Everything that was suspected as being the reason was tested and passed. Finally he checked the DFI module. Hello...it is apparently 'out of spec'. Whatever that means. He's put a secondhand replacement in and now we can but use the car to see if that has resolved the problem/s.
Fingers crossed.

Update. There have been no further issues with the car, so the problem had to have been the DFI all along.

my vp,never used to start first time since the day i got it,
many looked for the problem to no avail.
fuel pump[ died on me,fitted new one and a filter,
suddenly she starts first time,
the problem was a near blocked filter.
7 mechanic's and more than a few $ spent.

my theories..
if holdens are like their ford counterparts then they transponder key unit have rolling codes, which means every time you use the key the code in BOTH the vehicle and key change. You need to use all of the keys programmed to the vehicle at least once every couple hundred cycles of the key otherwise your spare key 'falls out of the system' which can cause all sorts of problems

another possiblity is that this sensor was not plugged in properly and neither was the vehicles computer - australian assembly is extremely poor.
if the comp was getting a reading out of operating range for that sensor it may have thought the engine was overheating hence the fan and the no start.
when you removed the sensor, the comp had no input and therefore substituted it for a default one. once it got replugged it had a clear reading and behaved normally.
or... just unplugging the comp for 24 clear some random fault.

orr... its a piece of shit holden (as are frords), all aussie cars are crap, sell it and buy a reliable toyota or a nissan and spend the money you save on your bike(s)

...because I just know that there are those of you itching to know

The car gave further starting problems. So we replaced the CAS. The old one seemed ok, but was covered in metal filings. No sign of where they'd come from tho. Again, the car performed fine. For a week.
So, off to Holden for a computer fault code diagnosis. Clear of all faults.
Hmmmm? Lucked upon an auto electrician who is a Holden fan...he checked (was the only one to do so) the inner surface of the + clamp on the battery. Corroded to buggery. New clamp, and a decent connector for the low tension lead to the ECM.
It's been nearly 6 months now - no further problem.

Moral of the story? When you have electric/electronic problems, check the simplest things first, starting at the battery connections.

A bit like us really....
Corroded on the inside - rustic on the outer!
Will have to start pouring the alchohol over myself instead!!

Not only the simplest but, in this case anyway, the cheapest! All those dollars gone down the gurgler

Used to have a vs... every now and then it would turn over but not start... maybe 1 in a hundred times of starting it, it just wouldn go....always at the most inconvenient time!!!! took it into the shop as it was under warranty... they put the diognostics on it...and said there was nothin wrong with it but i refused to take it away untill it got fixed. So it sat there for three days and on the 3rd day as the mechanic went to put it in the shed for the night....the bloody thing wouldn't start (yay) there was a fault with the immobiliser unit!
