Hey Guys
2004 1800R
Wouldn't start this morning. Turns over like it wants to start just wont fire. Has gas and the fuel pump cycles when I turn the key on.
Pulled a plug and put it back in the boot, cranked motor and no spark. Blew air out of plug hole and I could smell the gas so I know it has compression and is getting gas. There are 2 coils so wouldn't the other coil fire?
Pulled seat and checked fuse coming off of + side of battery as well as all other fuses in fuse box.
What am I missing?
Need my wheels, any thoughts would be appreciated.
Thanks

What was the last thing you did to it???
Wash it??? Knock camshaft position sensor(CMP sensor) connector off???
Another 1800 had a bad wire crimp on the CMP sensor terminal terminal.

Crankshaft Position Sensor produces pulses.
CMP sensor has some control over the timing of the pulse.(IMHO)

Since the FP primes, the Black/White wire (+12v from Engine Stop Relay) seems to be good.
Both sensors produce voltage and have some DC resistance. (192 ohms)

Any flashes of the MIL????
With IGN on, Black ECM connector removed, you can scratch a GROUND wire onto
the Blue/Yellow or Yellow/Blue coil wires to see if you have spark.

The Ignition coil has one HV winding with the spark plugs on the end of each wire.
The spark plugs are in a series arrangement. Sometimes this can create a no spark
situation if one end was open.
One would think that it would crank and run on one cylinder.
Check the resistance from spark plug cap connector to the other one same cylinder.
32k to 36k ohms.

Kick stand UP or Neutral switch GROUND required for Ignition Green/White wire on the Gray ECM connector.

What was the last thing you did to it??? lifted gauge to put bib on tank. new jacket scratches it
Wash it??? wiped it down, no water

32k to 36k ohms. i'll check these out and thank you

Camshaft position sensor was not latched.

The other one I mentioned---bad crimp on terminal or some oxidation/corrosion.

ECM must see a Ground from Neutral switch or Kickstand switch when UP.
Diodes in circuit, the black plastic 3 pin device in the fuse box.
The last sentence on my previous post.
