..

not told is engine misfiring still,? (besides DTC errors)

1996, 350V8 engine, 5.7L new name today.
C1500 right with C in front? not K1500>?
VIN R coded Automatic trans.
1351 (no front letter told) why post DTC lacking full and complete DTC????
answering for USA spec, cars only me.
i get only 1 hit

Trouble Code: P1351 (5.7L V8 VIN R Auto)
ICM Ignition Control Circuit High Input so after replacing the part
we reset all DTC errors using the scan tool (a button on it)
and drive and see if it comes back or otere pop up.
if does p1351 again,
the wiring is bad to it.
the SM states this

• ICM control circuit is open, shorted to ground or shorted to B+
• ICM power circuit is open (check power from the ECM1 fuse)
• ICM is damaged or has failed
• PCM has failed

bad grounds to all that.
the ICM step 4 in the manual told you the ICM must be mounted
not just nakked(sic) ever but with thermal compound.
like seen on computers today,(called heat sink grease (SLANG)
MUST, OR IT OVERHEATS, FOR SURE, LIKE CLOCK WORK
BEST IS NEW DISTRIBUTOR THIS OLD. IMO
AND ALL Wiring to to it clean and tight , no rust or bad connections.
even loose fuse or one that is damaged, ENG1 and ECU1.


zzzzzzzzzzzzzzzzzzzzzzz

zzzzzzzzzzzz

until you fix the fault the code will come back
code p1351 is cylinder misfire with fuel cut off--cylinder 5==causes --wiring connections--fuel level low---ignition/fuel system---intake leak--mechanical fault

Ignition coil control circuit high voltage. P1351 Chevrolet Ignition Coil Control Circuit High Voltage

GM General Motors P1351: ICM Circuit High Input Conditions Details: With engine speed less than 250 rpm, ignition control enabled, the VCM detected that the ignition control circuit was more than 4.90 V

The code 1351 is a problem with the ignition diagnostic circuit, and code 1343 is not a common code for Ford products in the US.
It may have something to do with the accelerator pedal sensor.
You may need someone with a scanner and a shop manual to troubleshoot the codes.

possible solution http://blog.bavauto.com/6891/bmw-fault-code-misfire-cylinder-5-p1351-m54-engine/ from bavarian autosport. have used them for parts for several years and their techs are very knowledgeable. 1343 is code for cyl 1 1351 is for cyl 6.

Here you go - this'll help you translate your engine codes. Looks like your getting a "Multiple Cylinder Misfire With Fuel Cut-off" and "Misfire Cylinder 5 With Fuel Cut-off". Hopefully you just need a good tune up, but this should point you in the right direction. Good Luck.

P1354 Variable Valve Timing System Fault

NOTE:Variable Valve Timing (VVT) sensor is also known as camshaft position sensor.
The Variable Valve Timing (VVT) system controls intake valve timing in response to driving conditions.

Possible causes are:

1. Incorrect valve timing P1346, P1349, P1351 & P1354
2. Faulty oil control valve P1346, P1349, P1351 & P1354
3. Faulty VVT controller assembly P1346, P1349, P1351 & P1354
4. Faulty ECM All Codes
5. Jumped timing belt All Codes
   
6. Faulty Camshaft Position Sensor P1346, P1349, P1351 & P1354
7. Faulty O2 Sensor (Bank 1, Sensor 1) P1133 & P1135

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.
