Remove and check the (3) 32 pin ECU harness connector pins and clips for oxidation; firmly snap the connectors onto the ECU harness connector receptacles. Trace the ECU wiring harness along the firewall behind the valve cover and closely inspect the split wire loom and wiring harness in the...

YES... One of the replaced sensors may not be functioning properly. What manufacturer did you use for the CKPS and CMPS ? Forum members have had problems when using certain aftermarket ignition parts. Perform a test on the CPS to determine IF it is working properly.

When you checked power to the coil; did you only check the power at the positive terminal of the coil or did you check power across the positive and negative terminals while cranking the engine over ? IF you only have power to the coil positive terminal and not the negative; you need to...

The only thing to add to what LONGJP2 posted above; would be to ensure the vehicle is on the ground with full vehicle weight on the tires while loosening and retorquing the control arm bolts.
