After I replaced my 885 head due to a prematurely snapped timing belt I can not start my car. everything is buttoned up belts are in place. there is fuel already tested for spark. the car cranks over but won't stay cranked. checked the fusible link and received no voltage. What is the best way to replace this link? There isn't a lot of slack and I don't want to cut the wire. Seems like such a stupid question but want to be sure need to get this car going so I can go to school and work tomorrow.

did you mix up the cam and crank position sensors, its easy to do as they both are the same and next to each otherShawn @ Bimmerbuddies

If the engine cranks, fires, then dies the cause is probably not the fusible link. It powers the DME and if bad the engine will not fire at all. Intake leaks, a fuel system problem, or a flaky CPS are more likely to be the cause in this case. You have to disturb the wiring of the CPS to change the timing belt (or the head) and it isn't known for an old CPS to give problems after that. In a like manner it is easy to introduce intake leaks when the head is re-installed.The car makes it possible, but the driver makes it happen.

If you want to help, great, but if you're not really certain, a misinformative post is less helpful than none at all.

Originally posted by travish325I dont see any unhelpful posts, car wont start is a pretty generic question. Theres lots of crap it can be. Being that the head was off and it ran before sounds like timing, leaks, valves ect all stated already.. Op says he has fuel and spark. How can there be bad answers when the question doesnt even make sense. Car cranks but wont stay cranked? Wtf does that mean?

Originally posted by travish325Crank sensor plug is next to the rpm sensor plug (or whatever the technical name is), that runs to the number 6 plug wire correct? Which gives you your tach signal?
Is that the cam sensor? I searched for hours trying to find something on a cam sensor on an m20 and found nothing. Where is it?The car makes it possible, but the driver makes it happen.

if you look down on the right front of the engine just next to the a/c compressor you will see a black plug held in by an allen key. that is your CPS. that wire runs behind the upper rad hose and behind the therm housing into the bracket with the injection timing plug sits.
remove that and replace it with a good one to eliminate the potential problem.sigpic
