Four digit codes are brand specific, in your case code 1351 means the computer is finding high voltage in the control circuit for the coil which does go to the ICM. The ICM grounds the coil like a set of points once did.
My guess would be a faulty coil or a ground connection somewhere. The coil may be grounding thru the ICM instead of thru the block. Or the ICM ground is not strong enough to carry the current from the coil.

Yes. First, in the fuse block under the hood check INJ A fuse and INJ B fuse. INJ A fuse is circuit 1039 which feeds the coil. If the fuse is OK, replace the coil electrical connector. I stock 2 of these at my dealership because they are needed quite often.
FYI P1351 is an ignition coil control circuit DTC.

Hi

Have you checked the EGR valve, and or the air flow sensor? both could cause it not to start!

Also ensure the earth battery lead has a good connection to the car body from the battery.

Please get back to me if your unsure about these parts.

Regards
Dan

Check the connections at the vehicle control module
(vcm) located on the left fender. Check for bent-broken pins or pins that have pushed through the plug
Make sure the connections are tight and dry.
Do the same at the coil. Also check for any exposed
or shorted wires between the two. Hope this helps

P1351


That code is for the ignition control circuit. It is the white wire that runs from Ignition module to the VCM. this controls the timing.

This is either a bad wire/connection from the VCM to the ignition module, ignition module, or VCM. I would check them closely in that order. This can commonly be a bad ditributor

Tests/Procedures:
1. Use an air gap spark tester set at 25-30 KV and check the output from the coil wire and then at multiple spark plug wires.
2. Bring the engine to Top Dead Center (TDC) #1 and verify the rotor is pointing to the 8 that is cast into the distributor housing to make sure it is not out of time.
3. If the distributor is dropped correctly, but spark is erratic at the plugs but good at the coil, replace the distributor cap and rotor with one from the dealer.

Potential Causes:
Distributor Cap
Incorrect Distributor Timing
Ignition Rotor

Tech Tips:
This trouble code can set from extended cranking and is most likely not the cause of the problem as long as there is spark
Tests/Procedures:
1. Using a Digital Volt Ohm Meter (DVOM) or lab scope, check the White wire at the ignition module pin B while cranking. This should be a 0-5 volt square wave pattern any time the engine is cranking or running.
2. If there is more than 5 volts on the White wire at pin B, check the White wire from the Powertrain Control Module (PCM) to the ignition module pin B for shorts to voltage.
3. If the wire checks OK, check powers and grounds to the PCM while cranking. If the powers and grounds are OK at the PCM, the PCM will need to be replaced.

Potential Causes:
Ground Ignition Module Power
Powertrain Control Module (PCM) Wiring
Tech Tips:
Conditions for Setting the DTC The Ignition Control voltage is more than 4.9 volts.


Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day

I am getting code p1351 on a chevy s10 it will not start could this be the timing chain


No this is not a timing chain
P1351 CHEVROLET - Ignition Coil Control Circuit High Voltage


Conditions for Setting P1351:

The voltage on the ignition control circuit exceeds 4.9 volts, and the engine speed is less than 250 RPM.


Bottom line?

Most likely its a bad Ignition Control Module.
