Ok, I'll try to keep this short. Me and a buddy bought this '88 Turbo Targa two weeks ago in a no-start condition. We believe it has sat for 20 years from 1995-2015, was driven from 2015-2018, and sat from March 2018 to now. The previous owner showed videos of it running; the car has 66,000 miles. We have no spark, but the car cranks strong and steady.

What we've tried:
  • Changed battery
  • Testing spark plug wires per OEM spec (GOOD)
  • Testing coil packs per OEM spec (GOOD)
  • Replacing spark plugs with OEM spec plugs (GROSS, REPLACED)
  • Swapping igniter with another known good unit with no improvement (GOOD)
  • Pulling fuel tank and fuel pump to confirm pump was in working condition (GOOD)
  • Checked Compression (150 PSI 1-6)
  • Jumped Diag port to read codes if applicable (NO CODES; "HEALTHY" BLINKING CEL)
  • Checked all fuses related to EFI, ECU, etc. (GOOD AND ORIGINAL)
  • Checked all grounds on intake manifold, for coil packs, etc. (GOOD)
We have now pulled the Camshaft Position Sensor (CPS) to check that the unit is in decent shape, reset timing to make sure it's 100% correct, and rehab it if needed. However, the usual problems with the brittle wires on the sensor do not seem to have manifested themselves in this unit (see pics). We wanted to ask you fine people if there were any resources you could point us to for checking to see if the CPS is in good condition. We confirmed G1 & G2 to ground were within spec and that we had NE to G read infinity which is the first thing that's stood out to us. Any suggestions with that in particular? It seems that we've confirmed pretty much everything is good from the ECU down the line except for the CPS, and we just want to know what we can do to fix the CPS before shelling out $200 for the Rockauto refurb. We're frankly pretty stumped with what should be a straightforward issue here.

Any help is greatly appreciated.
