Crank, no start

[richardsMk8]

My 1998 Lincoln Mark 8
Crank, but no start. I disconnected the crankshaft position sensor, stll no start. I took off a coil pack, grounding the end of the spark plug, to grounding. No spark. Ok, so now what? What else could be wrong, that causes no spark?

You can't just disconnect the csp sensor
You need a good one and sometimes the harness fails too

Since I changed the crankshaft position sensor, and it did not want to start, i thought, why don't I change the camshaft position sensor, too. So, I changed that, then the Lincoln Mark 8, started right up.

when you changed the camshaft sensor was there only one and that one being on the driver side?

 

[richardsMk8]

No. It's on the passenger side of the crankshaft.

Yes

Let me understand you. I am referring to a 1998 lincoln Mark VIII. The crank sensor is down low in the front of the passenger side of the engine.

Th cam sensor is high on the front of the driver side and it is hidden behind if I remember right behind the power steering pump.

I am struggling with a no crank. I've send the PCM out to remove the anti theft function but have not reinstalled PCM.

I could not get a signal out of my OBD2 port.

Not my picture

Thank you so much. I replaced both and the Lincoln is back to life again.

Now, I have another problem. Check engine light is on, and I have codes PO705, PO708 and PO1414. I changed the transmission range sensor. It did not fix the problem. With the Air injection pump, I unplugged the connection to the pump, connected power to the pump, and the pump came on. That means somewhere in the circuit, the other 2 wires, there is no power. What do I need to check, to make the code PO1414, to go away?
