New fuel pump, all sensors have been replaced. Crank sensor has an ohms reading, cam sensor does not. Fuse block ECU fuses show 12 volts. Fuel pump check shows 12 volts. Key in start position with good pump relay fuel line disconnected at pump, does not pump fuel. Jump pump relay fuel pump operates. Pulled #2 spark plug cranked with plug connected to wire, could not see any spark.

Good morning,

Are there any codes set?

If you have power to the pump and there was no flow, the pump is not working.

You need fuel pressure to run. It will turn on for 2 seconds with the key on for priming and will be on full when cranking.

Did you check for spark at the plugs?

Did you check for compression?

Fuel does pump with key on, there is uniform compression, there is no spark. Unable to see spark with plug installed in wire and unable to feel spark with screwdriver in wire and touching screwdriver.

What is the fuel pressure?

What is the compression?

When you crank it does the tach move up a little to show RPM?

Compression is about 190, unable to read fuel pressure due to sealed fitting on fuel rail. Do not have adapter to fit at this point, tachometer does not move, got about 9 volts on one pin of coil pack connector with key on. 0 at other 3 pins. Is this reading correct for power to coil pack?

Maybe it could be a bad NO.1 wire? Do you have another new wire to try or use one of the old wire to see if you can get a spark?

No, it should be battery voltage. 12.2 volts or more.

No tachometer signal could be the crank sensor.

I attached a diagram of the coil for you.

The green is powered by a fuse I circled in one of the diagrams.

Check for power and let me know.

Crank sensor shows a reading of 630 on the 2000 ohms setting with negative lead on the center pin and positive lead on the pin left of center. Does this reading show a bad crank sensor?
