No spark

[jsturgill]

Heres the deal. 2g 420A nt, mt. overheated and cut out. Now it will not start NEED HELP!!!! It is not getting spark.

What i've checked:
1. Spark from the wire (NO)
2. voltage at coil (No) (swapped coil from another 420A that has been sitting in my driveway STILL NO SPARK)
3. voltage from crank sensor (5V on 2 leads)
4. Checked fuel line (still there)(and working)
5. Checked timing. (seems to be OK)
6. Checked compression ( Well I didn't have a compression tester but I stuck my thumb in each hole and felt it was getting some type of compression.)
Battery is weak but should still supply spark, right?

2 codes popped up o2 sensor (Would that prevent it from getting spark?) The other was speed o meter (Would that prevent it from getting spark

I don't know where to go from here. Hoping someone could help me on here..

Thanks in advance!!!!!

Well it could be the battery, or it could be a ground somewhere. I would charge the battery and then try. Something similar happened to me a while back my crank sensor went bad, so that is a possibility as well.

Are the fuel injectors firing? The ECM uses the CAS signal to generate ignition and fuel injector pulses.

Stupid question but how do i check the fuel injectors? Voltage? What is normal?
