No tach bounce so your most likely culprit is the speed and reference sensors and not the dme, you can check them with a multi meter set on 20k ohms they should read around 600-1200 ohms using the center and left pin. Kinda a pain to get to but you can get the parts of pelican parts
Thanks for this but I need the follow-up videos! I just bought a 1987 944 base for a $1000. It's been sitting in a carport since 2006. I had to have a key made and am ready to start replacing fluids. It appeared that you did not initially replace the fuel pump. Is that correct?
Hard wire your fuel pump to test .once you do have a working pump pull out DME relay and prime fuel system 30 &87b hard wire that way your system will be full then put relay back in and she will run
Changing the oil etc is all well and good, but rubber timing belts do not like sitting and the rubber deteriorates with time. Trying to start a car like this without checking the condition of its two timing belts is pretty risky.
Make sure the ECU is firing the injectors and spark plugs (or is it just a distributor?). No idea how to test that, though. Might also check fuel pressure.
It's a distributor, there's only one ignition coil. But yes, I suspect that lack of spark is the issue. I'll cover that in the next vid once I do a little more troubleshooting.
I have no record of it being changed, pretty sure it's over 6 years old. That's part of why I haven't been messing with it too much lately, don't want to risk the belt snapping. I'm considering pulling out the engine and just doing everything at once- timing/balance belt, water pump, clutch, all the engine gaskets, cam chain guides, oil cooler seal, etc.
Cool. Easy fix, just a bit time consuming if you're doing it for the first time. Also, be sure to inspect the tensioner pads for the 16v head. Good luck and have fun!
Great job Danny. I was really hoping it was gonna fire up. Looking forward to the next update. What are your plans for the 944S? You gonna drive it or flip it?
Matt Br80 I was hoping it would fire up, but things can't all be that easy, haha. If this was reality TV I'd just skip to the part where I triumphantly fire it up. I'm gonna do some more stuff to it in the next episode to see if I can get it running. I don't intend to flip it, I want to fix it and enjoy it.
I didn't really spend much money at all, don't worry about it. I ended up losing interest in the car and selling it to a local 944 enthusiast for more than I had into the car since 944S prices had appreciated by then. He ended up swapping the whole engine wiring harness because rats had eaten it all up. If I had this car today I probably would've figured it out, but back then I barely knew what I was doing. Funnily enough, I did a full timing belt service on a friend's 944 S2 pretty recently, so I did get to experience a running driving 944 in (arguably) its best form with the NA 3.0L.
