944 - No Starty

This video details troubleshooting a no start symptom. I lost power at 5500 rpms, "oh no" watch for the fix!

[@christopherkast8045]

Great video on this issue and fortunately have not had this problem on my 87 N/A. Just one thing about reinstalling the sensor bracket, How did you adjust so the TDC sensor had the proper spacing above the flywheel ?

[@curtisr57]

Thank you so much for posting this video! While there's no shortage of instructions online for replacing the sensors, this is the only bracket exchange help I've found. And, now it's off to the passenger side of the car to get at those 6mm bolts! Who knew?! I certainly never thought to try that. +1

Thanks man! No problem at all. You got it bro, a little patience and you'll be back rolling in no time!

is this a later car? i’ve heard in the later cars you have to literally break the bracket in order to get it out. i’m suffering the same fate as you and i would really like to just remove the bracket but if i can’t i’d rather keep the bracket in place and not lose the gap. thanks man!

Hey man thanks for the helpful video! Where have you been? Been watching ya for years.

[@artmchugh5644]

you can get some more room to operate just by removing your oil fill cap 😊😊😊😊😊😊😊another thing to tighten or remove the bracket bolts ,get a very short 6mm Allen SOCKET and 1/4 inch ratchet!!!

[@TE2REI]

You doesn't mention the distance between the sensor and the wheel after removing or installing the sensor gasket ;-)

[@eriktml]

no way! im driving my w211 rn because my 944 wont start haha. great minds think alike lol

[@fcimports9823]

Lololololol. That's awesome!

[@slow9445]

lots of people gap the sensors is it really that important?

[@devorahacts]

Sorry, you kept saying in the beginning, "this coil". Which coil? And where did you take the Reference sensors out from? Ar they near the front? Thanks.

[@fcimports9823]

devorahacts the coil is the ignition coil located at the front of the engine near the manual override for the headlights. It sends electricity to the distributor that goes to each spark plug. The reference sensors are located toward the firewall at the back of the engine. They tell the ECU (brain) that the starter is turning the engine so provide electricity to the ignition coil. If you look through my videos I have a whiteboard animation explaining the process. Thanks!

[@timcomeau420]

@@fcimports9823 The reference sensor doesn't tell the DME anything about the starter. It tells the DME where the crank is at so it can fire the coil at the right time. The coil already has electricity to it. The signal is to GROUND the coil so it fires to the distributor rotor.

[@shaquandavis1884]

Great video! I'm going to try removing my reference sensors and checking for dents

[@fcimports9823]

Yeah man, you can always check first. Just remember on the re-install to make sure you have the proper clearance. I'd just mark it because there is a little play in the screw holes

[@timcomeau420]

There's only 1 reference sensor, the second is the SPEED sensor.

[@corymoll9572]

did you say this broke at 5700rpm???? crazy high revs...I get worried pushing 1984 944 above 45000rpm

[@liamflynn6929]

You don't even reach the powerband

[@edwinlopez1896]

What is it if mine doesn't start but starts when you push it and dump the clutch I turn the key over but makes only one loud click

[@timcomeau420]

Could be your starter, your cables to the starter, or your ground wires. The fact that you hear a clicking sound tells me your ignition switch is prob ok.

[@marcolopez8110]

Were you buy those sensors

[@77magnuss]

You can get them at Pelican Parts, 944 online, Paragon Products...

[@marcolopez8110]

Tanks I try tomorrow I hope estar

[@frederickontour1478]

This is great! thank you!

[@fcimports9823]

Frederick OnTour no problem glad to help

[@alansimmons4071]

Great video, what about the spacing of the sensors when you put them in. The gap spacing to the gears on the flywheel, did you have to measure that or did you just put them in

[@lizard944]

Yeah, they should be spaced or you run the risk of them being chewed up by the flywheel cogs or misfiring if the gap is too wide. The manual says to take an old sensor and glue a 0.8mm washer to the bottom of the sensor to act as a feeler gauge to set the gap. You can use your new sensor as the gap tool but you'll want to use an easily removable glue so as to not damage the sensor end.The washer should be a little smaller than the diameter of the sensor so it will fit through the bracket hole. Bolt the bracket on loosely with the homemade gap tool installed on it then press it downward till the sensor (washer) contacts the flywheel then tighten down the bracket bolts. Then unbolt and remove the washered sensor gap tool and replace it with the new sensor. This should produce a sensor gap of 0.8mm from the flywheel .

[@timcomeau420]

Lizard 944 has the gap measurement correct, but the gap is to the starter ring, not the flywheel. The ref sensor is above the flywheel trigger. The speed sensor is over the starter ring.
