Cam Sensor Chronic Issue 900 1993

UPDATE: I received a Tamkken CPS on Saturday and a Bougicord today. I decided to wait and install the Bougicord today and....NO START. I am still getting no movement from my tachometer needle on startup.

UPDATE #2: Ran the OBD diagnostics. Disconnected the coil wire and turned engine in Mode 2. Got the 1-4-1 followed by continuous flashing. This is with the new Tamkken installed. I was able to start the car a couple of times but it is not consistent. Mostly no starts. I already cleaned the connector at the firewall and it looks to be in good order. There is spark to the coil for sure.

I tried both CPS's to be sure the Bougicord wasn't bad. No difference. I just looked over Porkface's process for diagnosing the CPS. I will get some help to turn the car over while I check spark at the coil, but even if the coil or the fuel pump relay is the problem, would it cause the dead tachometer needle on engine turnover?

I had the Fuel Pump Relay out of the car a month ago, but nothing was broken or damaged and it seated properly on reinstall. Still, that is something for me to consider.

But the tach needle ought to move if signal is reaching the control module right?
