So my daughter and I set of for the holy grail this morning. New Pelican Parts came in yesterday and we are going to make this 85.5 944 run.

This car has not run in 8+ years but I have drained the 8 year old gasoline/varnish cleaned the fuel tank with lacquer thinner. Cleaned the rest of the fuel system with lacquer thinner. Replaced the fuel pump, the fuel filter, the distributor cap, the rotor, the plug wires, the plugs, the timing and the balance shaft belts, the throttle body mounting gasket, the air intake boot, and cleaned the throttle body.

I'm feeling good about a successful launch.

No Start.

Pull a spark plug - no spark.

Check the coil after getting the rickifricafraking cover off of it and its OK. I had my daughter crank while looking at the coil primaries with a VOM and no signal at all. Next I went to find the DME brain to see if it had bad connections. Haynes, of course, said it was under the dash to the left of the steering column, Clark's helps me out that, no it is under the carpet on the passengers side of the vehicle.

Pulled the carpet and I have a DME connector but no DME.


I sorta figure that is why I have no spark and why I had to jumper the DME relay to get the fuel pump to run.

So now the big question. Which DME do I need?

The car is a 1985.5 944, N/A, with an automatic - oh, and it is red.

From grousing around the internet I figure it to be a Porsche P/N 944.618.121.04 and a Bosch number 0 261 200 077.

Can anyone confirm that this is the correct part number for my daughter's car?

TIA,

...Lee

i *THINK* you can use any DME from an NA after 85.5, except the '89 or from an S or S2. you should be able to get one off of eBay relatively cheap.

Hi, you gave the correct numbers for your computer. 924S uses the same computer as well. Same computer for manual or automatic 944's

Early '85 has the DME under the dash. Late '85 and newer have the DME in the passenger's side footwell. IIRC any 85.5 n/a DME should work fine.

The good news is that it shouldn't be too hard of a part to locate.

eBay item Number 320112134300

P/N 944.618.121.04 from the photos. Not my own auction.

When I re-built the head on my S, my daughter helped me do it. I had her lapping valves. She also helped me get to some of the small bolts, that my hands have trouble with. She wants to trade me her Corolla for the 44.

This is just an aside, but when I chipped my 83 944 years back, I discovered that my DME was from a 1986 car. As far as I know, the AFM was correct for 1983, so it appears that these cars will run fine on any year's DME as long as it is correct for the model. I would, however, err on the safe side and get a 85.5+ DME.

I would concur with CJ, but I would also move the DME to a better location, like under the steering wheel. I never will understand why they moved them.

CJ - the late cars will NOT run well with mismatched DME/AFM combos... IIRC it is possible to run the car with the combo you had, but i've tried the other way and it's not great at all (late AFM with early DME).

you'll definitely need an 85.5-87 DME

I can get my DME and KLR out in 10 minutes from the floorboard location without having to contort myself to get under the steering wheel. It's much easier to get at in the floorboard location IMO.

As far as relocating it goes, you'd need to do some modifications to the wiring harness to make everything reach. I really don't recommend it.
