Checked these 3 Relays and they were fine, but I replaced them regardless.

(I have reset the codes just to be safe, but it comes right back after you try to start).
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I did a full engine rebuild on an 01' Boxster S 6sp this winter. Took my time, $8k worth of parts from Pelican, should last a lifetime from here...
Now reassembled, but engine will not start (arghh).
1) First checked fuel pressure, zero. Appears DME not telling fuel pump to kick-in. Fuel pump works as I can hardwire it and get 60psi. Even after creating "manual bypassed" fuel pressure, car will not start. Thus no spark.?
2) Heard issues of relay issues with DME, Fuel Pump, & Ignition specifically. Checked these 3 Relays and they were fine, but I replaced them regardless.
3) DME giving error code P0336 "Camshaft Position Sensor A Circuit Range/Performance". So I replaced the CPS. The logical culprit. But to no avail. Still getting same code and no start. (I have reset the codes just to be safe, but it comes right back after you try to start).
All of this might suggest a wiring problem. But, no electrical issues before the rebuild, no damage to the wiring during rebuild or reassembly. Triple checked every connection in the engine and its all buttoned up tight electrically. This is a low mileage nice-weather only car only so no corrosion in the system.
Cars electrical system seemed perfect before the rebuild.
Im at a loss.... ideas, anyone?

JFP, I feel like a owe you a beer or three for the guidance.
- CPS is new. Both old an new exhibit the same problem.
- I pulled the 3 wire harness lines from CPE to DME. All checked out fine for continuity. Also resistance across the 2 lines with the CPE installed is at spec (~0.9 kOhm).
- Must be a DME? DME was working fine when I started disassembly. Battery disconnected throughout the build. Never touched the electrical. How often do DMEs fail??
Head scratcher...
Wanted to close out this thread with a resolution in hopes it helps someone else.
The crank position sensor and the cam position sensor share the same connection type. One is black, one is grey. Given the layout of the wiring loom you can, as I have found, connect the crank position sensor wire to the cam position sensor, and vice versa.
Problem solved. Although somewhat embarrassed to make the simple and amateur mistake!
