14 pin connector

Wally I'm not that great of mechanic so I'll have to ask a dumb question. How do I check for continuity to chassis ground while the starter is spinning the engine?
Thanks,
Ariel

Set the multimeter or Ohmmeter on the lowest resistance range. When you touch the probes together, you should get very close to zero Ohms resistance, showing that you have continuity between the two probes/leads.

Put one probe on the ground connection above the Central Electric Panel - this will be a bolt to the body/chassis with a bunch of brown (ground) wires attached. This puts one lead of the Ohmmeter at ground.

With Relay XX (Fuel Pump Relay) out of the socket, look at the diagram on the relay, and identify for certain terminal 86 in the relay socket. Recheck to be sure that you know which terminal (female 1/4" electrical socket) is 86.

Put the other probe on terminal 86 - there should be no continuity - the meter should read max resistance, often shown as infinity (signified by the "sideways-8 symbol). Have an assistant spin the starter. When the Crank Position Sensor sends pulses to the EZK ECU showing the crankshaft position, the EZK ECU will send pulses to the LH ECU. This will cause the LH ECU to ground the wire going to the 86 terminal in the relay socket. Since there is battery voltage on terminal 85, which is the other side of the relay coil, the coil will be energized, which will pull the relay contacts closed, which will energize the fuel pump.

The reason for all of this is so that the Fuel Pump Relay will not be energized except when the engine is turning. This kills the fuel pump in a crash situation...

Or hook a test light to power, put the pointy end in 86 and reach up and crank it and it should turn the test light on.

By the way, I would not use a test light on new car electronics (Wally's is the correct method) but I believe the EZK is robust enough to turn the test light on since its a relay circuit.

Here's my results in Red following Wally's instructions. - Remove Relay XX, the Fuel Pump Relay. Using the diagram on the relay, identify the four connections in the relay socket.
- Check for 12 vdc on terminal 86 when the ignition switch is on = 11.9 volts- Check for continuity to chassis ground while the starter is spinning the engine.
Positive probe to pin 86 and neg probe to ground. Volts = 0.00 Ohms .79
There is movement of the tach needle when the starter is spinning the engine.

My apologies - I screwed up!

Terminal 86 should have battery voltage when the ignition switch is on. Terminal 85 should be grounded while the engine is spinning. Look closely at the meter, and be sure that you know how how to read voltage, and how to read resistance (Ohms).

Just to follow up. Finally took it to a shop and Dave Zaprev figured out the issue. He replaced Crank sensor. I still have a high idle but it's running. I'll probably have to do another intake refresh to get the idle sorted out.
