I put the original back on. Everytime I had the balancer off I would check those reflector rings and I didn’t see anything abnormal

still having issues

Yes I am. I’ve replaced the harness that goes to the Crankshaft and camshaft position sensors along with the connector to the Ignition control module. The harness had continuity in the wrong places but even with a good harness the the problem remains and I’m thinking the bad harness may have ruined my new Camshaft sensor because when I unplug that sensor my car runs perfectly all things considered.
I need to go get another sensor but I’ve been distracted with other projects.

Concerning the fuel pump issue I’m still not sure. The PCM will not send power to the fuel pump relay. I’ve even commanded the PCM to turn the fuel pump on and the PCM says it is turning it on but there’* no power.
So I continue to use a toggle switch to jump the relay if I need to move my car.

its a hall-effect sensor and its only wired to the ICM. I dont know how that can be the case. To me, the only thing that makes sense then is your car ignition control module is seeing impossible readings from the cam sensor and its freaking out. unplugging it your car uses an algorithim to guess 1/6 chance of getting the fuel sequence right. sounds like the camshaft isnt passing the magnet at the right time?

The PCM grounds the relay and that then sends power to the fuel pump. The Pcm doesnt send power to the relay

GM has the pcm send power to the fuel pump relay. There’* been some replies about this issue On this thread. There’* a wiring diagram that I posted that proves this and I’ve also checked this out on my other Buick 3800 and the PCM does send power to only the fuel pump relay.

When I have my diagnostic tool reading the crankshaft and camshaft readings they will all be in sinc say at like 800 rpm’* but at random times the camshaft sensor will spike to 1100-1200 rpms while the crank remains at 800. That’* what is causing my car to sputter.

CRANKSHAFT POSITION SENSOR SYSTEM DIAGNOSIS

CIRCUIT DESCRIPTION

The ignition control module (ICM) monitors the crankshaft position (CKP) sensor sync signal when the engine is cranking. The CKP sync signal is passed from the CKP sensor to the ICM on the CKP sensor 2 signal circuit. The CKP sync signal is used to determine the correct cylinder pair and initiate the ignition coil firing sequence. The 18X reference pulses are passed from the CKP sensor to the ICM on the CKP sensor 1 signal circuit. The 18X reference pulses are used for fuel injection and ignition control. After the ICM receives both signals, the ICM passes the 18X and 3X reference signals to the powertrain control module (PCM). The camshaft position sensor and the CKP sensor share a 12-volt reference and a low reference circuit. The CKP sensor consists of the following circuits:

• A 12-volt reference circuit
• A low reference circuit
• A CKP sensor 1 signal circuit
• A CKP sensor 2 signal circuit

Fuel Pump Relay Circuit StatusFuel Pump Relay Circuit Status indicates the diagnostic state of the output driver for the fuel pump relay control circuit. The scan tool displays Fault, OK or Invalid State.

your car doesnt have a camshaft-tachometer.. can you show me that live data?
