No spark
Cleaned and replaced the iac disconnected negative battery cable to let D1 relearn idle.
Replaced crank position sensor. The old one was loose, no shielding, missing its oring and the was no spacer to be found.
It seems to run fine but in the 10 miles of driving in stop and go traffic it has died twice. Is it still learning the idle positions or something else going on? Both were filthy. Thoughts?

Walt,
That post was really scattered. Here is the recap...
My 98 D1 wouldn’t start. Battery was good. I had good fuel pressure. It would turn over but not fire. I had no spark. Reached out to another forum on FB and they suggested to unplug CPS and see if it would start. I looked in the rave for the location, looked at the wrong diagram and inadvertently unplugged the IAC. It started, so now with my brain turned off, I ordered a new CPS. When it came 5 days later, low and behold it did not look like the stepper motor at all. I went back to the Rave and looked a little closer and found my mistakes and the fact that both parts can cause the engine not to start in similar ways. Multiple folks suggested to clean the IAC and reinstall so that is what I did.
First of all, getting to the crankshaft position sensor is a real bugger laying on your back and not removing the exhaust. Reading the Rave, the process is pretty straight forward... remove the two bolts holding the CPS shielding (no shielding on mine). Remove the screw holding the CPS in place (the screw was the but not tight, the CPS was wobbly in the hole). I am not sure what the spacer looks like that I was supposed to transfer to the new CPS, but the new CPS had an oring that the old one was missing. The old one just kinda flopped around in the hole. Everything was slathered in oil, inside and out (the whole sensor including the wire harness). The old CPS also looked a bit burnt and caked with sludge on the sensor tip.
So I guess the question is “ Is the o-ring the spacer referred to in the Rave?” “ Am I missing something that anyone sees?”

couple of thoughts.....
- how is the wiring to the CPS? It is often found to be burnt because it is close to the exhaust manifold/down pipe. That could be one source of the issue.
- the spacer for the CPS really needs to be correct...but I'd expect such a problem to be consistent, not intermittent as you describe. In other words, if it weren't correct, I wouldn't start at all. In any case I'd ring up the parts house where you bought it and try to find someone knowledgeable about that spacer/o-ring. The folks at Roversnorth, AtlanticBritish, and Rovhafarm have been good to me in sharing the knowledge I need to do the job correctly.
