2005 gmc envoy I have a codes p0351 p0352 p0353 p0354 p0355 and p0356

p0351,p0352,p0353 and p0354. It won't start because you have four cylinders not firing . P0351 - Ignition Coil A Primary/Secondary Circuit Description: See the description for DTC P0350. Possible Causes: See the possible causes for DTC P0350. Diagnostic Aids: See the diagnostic aids for DTC P0350. Application Key On Engine Off Key On Engine Running Continuous Memory Coil-on-plug (COP) ignition testing - GO to Pinpoint Test JF . GO to Pinpoint Test JF . Coil pack ignition testing - GO to Pinpoint Test JE . GO to Pinpoint Test JE .
When you see these codes , it's time to worry . These ford coil on plug system's can fry the transistors that control the coil firing . New computer or reman at ford $ 800.00 buck's then it needs to be programmed (dealer) What engine ? 3.0 v-6
This happens when the spark plug's are neglected , gap get's to wide , make's coil's over heat an break down , spark goes through the primary wire to the computer . Your best bet , take it to a qualified repair shop.

all refer to the coils A,B,C,D===causes wiring, ignition coils ECM
for all to go out at once , I suspect a harness connection ot a failed ECM
substitute the ECM with a known good one to prove it before buying an ECM

All those codes are the same BASIC code just for different coil pack secondary. You need to check the wiring from the coil packs and make sure they are all grounded properly. Corrosion or loose connection at a bus terminal can cause this. Here is a link: P0352 OBD II Trouble Code Ignition Coil Primary Secondary Circuit...

P0352 Chrysler Ignition Coil 2 Circuit
They all mean the samething ! No power to the coils , all the coils are open , the PCM is bad . Something isn't connected or you blew the fuse for the coils .

P0300 - Random multiple cylinder misfire
P0301 , 302 and 304 - Cyliners 1, 2 and 4 misfire
P0351 - Ignition coil A primary/secondary circuit malfunction
P0354 - Ignition coil D primary/secondary circuit malfunction

Misfire P0351,P0352,P0353,P0354,P0355, P0356 Meaning secondary circuit A,B,C,D,E,F . You may need a PCM If your car has a NGC controller it may have melted the ignition coil mounted on the spark plug. For these to happen You have a defective coil driver circuit in the PCM . This is a multiple coil failure, Before we go there lets do the basic are the connector connected? How about the conection at the juction area all connected, then pcm failed. These are secondary what is the secondary the signal that allows the coil to collapse the magnetic field and gives spark.

bad ground connection for coils or harness is bad for coils

That's pretty high but not unheard of. What model car is it?

you may have a problem with yuor ingnition system

Have your ignition coils replaced
