Just quick update:
Disconnected ignition switch , bypassed 30-15 ignition on 30-50 cranking. Engine starts and runs while 30 and 50 connected then it dies when released. The same result as before so at least now I know that ignition switch is ok
Also rechecked all fuses. All good.
There is a weird switch (not factory)with permanent 12V with one wire going to radio (probably memory) and from the switch to windscreen washer motor to the front. need to track what is going on there.
Was there any immobilizer in 924? I have something on the key ring which goes into the plug beside the ignition. The previous owner said they removed/bypassed that but when I looked on that bypass it was that wire with permanent 12 into radio.0 -
some had immobilizers but if yours has 1 it wouldn't start atallJust quick update:

Thx for tips
I will look into it tomorrow. I believe all the fuses are fine on both ends but will recheck that tomorrow.
DME relay seems to work fine, I did check it out of the car and also re soldered 3 or 4 joints.
The plan for tomorrow is to install fuel pressure gauge and test the pressure when cranking and also after 60 min.
Possibly checking injectors for blockage/spray pattern. (the old filter was fully blocked when I bought it)
Amount of fuel pumped in 30 sec.
All hoses again
Is there any sensor which is required for engine to run?
K jetronic seems to be pretty simple system, so that might be next step.0 -
Yes the Kjetronic is very easy,but if it starts then stops it has to be the ignition switch failing that it might be the distributer they tend to play up,what year is it !Thx for tips

It runs with the starter engaged? And then cuts out when you release the key? Its the Ballast Resistor fitted to the live supply to the Ignition Coil thats at fault, either fit a new one or bypass it and fit a 12v coil0 -

Yes exactly. So should I look for new coil?
To find out probably need to fit other one and try to start.
Is there a way to measure coil or ballast resistor?
Thanks for tip mate
I'll bypass it tomorrow/today from battery to positive on coil and try to start. If it runs fine time to source new ballast resistor. seems to be fun part to find 0 -

It is running thx for all the help
I did bypass the coil from the battery. First it was quite a struggle but after cleaning spark plugs and letting it dry from fuel it started no problem
It is running little to high 1200-1300rpm but I know vacuum hoses are not in the best shape (loose) and pretty much all connectors need to be stripped and cleaned.
The mistake I made was the measurement on the coil. I didn't realize that it had ground on both ends. With power probe it was clear that it gets positive voltage while cranking and no voltage (ground) when in run 2th key position.
The question now is going to be locating that ballast resistor ( I looked everywhere... almost) and buying/refitting new one.
Also the car is 1981 but the wiring diagram seems to be for ones made 79-80. So I was checking wrong ones all that time.0 -

After a few years break from owning a 924, I finally sold my Honda and bought myself this baby:
The car was used very little for the last decade or so and does need a lot of time and love to sort out all the minor imperfections, but it is a good base, so I am happy overall.0 -

ThanksWow, that looks in great shape! Congratulations!
I think it was a yellow 924 that lived near me as a kid that always made me want one. What year is it and what kind of stuff needs to be done? I hope your planning on driving it because I'd love to see it on the road..
The bodywork is in great condition and I would say more less as good as it gets on a car, never mind a 31 year old car.
She is a 1984 model, standard 2-litre engine. The suspension is OK, but the tracking needs to be adjusted to make it perfect. No other issues discovered there. The brakes work fine, however both of the front callipers are sticky and I am going to work on them this evening to see what's what (just bough a bucket of Red Grease for the job).
Another bits that need attention after my quick inspection after the purchase:
- Injector seals (ordered, should be delivered today, but no sign of yer man, so they will arrive on Monday most likely),
- A new set of ignition leads - ordered,
- New distributor cap and rotor arm - ordered,
- Air filter purchased, will put in this weekend,
- The alternator cooling hose - ordered,
- The fuel injection breading pipe cap - ordered,
- The bonnet opening lever set - ordered,
- New gearbox oil will have to be selected, ordered and changed,
- Wheels need to be balanced,
- I may replace the spark plugs in near future,
- I will possibly check the engine valve clearance soon,
- A new engine breather pipe - ordered (the old one is cracked),
- The ignition leads holders (2 nr) - ordered,
- New oil pressure sender - ordered,
- Speedometer in km only - ordered,
- New expansion tank rubber mounts - ordered,
- I am sure I will throw that radio away and put something that suits the car (the automatic aerial works, which is nice),
- The backlight bulbs on some instruments need to be replaced,
And... possibly a good few more bits and bobs, as I am constantly going through the car when I find a spare minute or two.
Interestingly, I found in the booth of the car:
- a new fuel pump,
- a new set of Bosch fuel injectors,
- some various genuine clips for the interior,
- an old cam belt (and alternator belt) in a Porsche box, so I assume the belts were recently replaced.
All in all, a nice project and although I wasn't too happy as I discovered so many faults with the car, but they are nothing major and I will get it all sorted in a matter of weeks.
Sure, the car is going to be driven. No point in just looking at it

Wow thays an easy enough list. ..Apart from maybe the front calipers.0 -
Eh, no... I though they are bad, but just got the callipers removed and checked through with a bottle of beer. New piston rubber boots are needed and another hour or two with more beer and it will be all sortedWow thays an easy enough list. ..Apart from maybe the front calipers.. 0 -
Thanks. I am just back after getting more work done to the car - have completed the valve clearance adjustment, so another small step aheadShe looks lovely! One mod I was thinking of doing that I see your doing is the Speedometer in km only. Where did you get one of these and how tricky a swap is it?.
I got the speedometer locally from a scrapped car (don't have it yet, waiting for the delivery), but I guess you can get them on ebay easily. It is not just the 924 speedometer I do not like, but any speedo with miles and km, they just look very messy with double scale and I prefer to count in km anyway.
The swap operation of the speedometer is an easy task and I believe shouldn't take more than 15 minutes. The speedo seats in with a rubber seal and needs to pushed out. There are two screws holding the cluster located at the top of the cluster looking up from behind the wheel.0 -
Yeah, that set will do, but you can remove and replace the speedometer only.I was looking at this
http://www.ebay.co.uk/itm/Porsche-944-924-speedo-kph-rev-counter-clocks-vdo-/191613090252?pt=LH_DefaultDomain_3&hash=item2c9d07b9cc
The sheer volume of cables at the back would worry me but if you can swap out individual instruments I may do it. I also hate dual scale speedo's
There are only a couple of bulbs / control lights to be swapped and the cable from the front wheel that drives the speedo.0 -

Thanks. The driver seat actually has a small tear, but nothing major. I can live with it for now.Great looking car it is quite rare to see dash and seats in such a good nick
I got most of the second hand bits from a breaker that has a few of these cars. But any consumables are easily available in good shops. For example the Engine Head Cover Gasket (half a circle shape seal - 2 nr required on both sides) I bought new from Micksgarage at a cost of €0.86, the air filter was only €8.46. Also got the driver side Bosch wiper blade for €6.51. Micks also have the Bosch injectors (that I found in the boot of my car), so it is not too bad. Parts are rather reasonably priced.May I ask, where u getting all parts? Like injector seals etc? I found that to get proper parts is a bit uphill battle
I remember with my previous 924 I owned a few years ago that I got a lot of spares from eBay (most of them I found in Germany).0 -

A couple of years i got injector seals from porsche ireland.
Cost less that €20 delivered for 4.0 -

I just decided to remove one of the brake callipers again, cleaned it up properly, greased, and put back together on the old seals. At least the car is now drivable.
I also made a few final touches to the valve clearance adjustment in the engine.
Now time for a test drive.
