Team Associated 3/23/2011P0351 – Ignition Coil A Primary/Secondary Circuit Malfunction

• Engine Hesitates
• Lack of Power
• Hard Starting Engine
• Damaged Ignition Coil
• Damaged PCM
• Ignition Coil has shorted

HouseCallAuto 3/23/2011No such code is applicable for a '95 Blazer. I suspect that you misread the code and what you meant to post was actually the code P0341 which is a code for the camshaft position sensor circuit. Notice that I said "circuit" and that circuit does not automatically mean cam sensor is bad. If I am correct that this was a posting error please let me know and I will advise what to check next.
walter 3/24/2011would the ans. below also include 1998 blazer. mine does the same thing only worse in the cold weather
HouseCallAuto 3/24/2011Leaving off the 1 (P351) vs P1351 changes everything. Does this ignition system make spark or not? Replace the distributor cap and rotor before we go any further. Update me if it still will not run.
HouseCallAuto 3/25/2011Yes it would cover the '98 Blazer as well. This answer is not the only cause but it is the most common cause 4 sure.
