Is Your Trusty GM Truck or Van Suddenly Unreliable?
There’s nothing more frustrating than turning the key on your workhorse 1997 GM vehicle and getting nothing but a crank, a stall, or a persistent Check Engine Light. If you’re dealing with bizarre electrical issues, poor performance, or a vehicle that just won’t start, the problem often points directly to a failing Powertrain Control Module (PCM). This isn’t just a part; it’s the brain of your engine. We’re here to provide the definitive, no-hassle solution to get you back on the road with confidence.
Common Symptoms & Your Solution
A faulty engine computer can cause a cascade of problems that are often misdiagnosed, leading to wasted time and money on unnecessary parts. If your vehicle is experiencing any of the following, a failing PCM is the likely culprit:
- Complete No-Start Condition: The engine cranks but will not fire up.
- Stalling and Rough Idle: The engine dies unexpectedly at stops or runs erratically.
- Check Engine Light with Communication Codes: Diagnostic Trouble Codes (DTCs) like P0601, P0605, or other U-codes indicating internal module failure.
- Poor Fuel Economy and Performance: A noticeable drop in MPG and sluggish acceleration.
- Erratic Automatic Transmission Shifting: Harsh or delayed shifts that aren’t related to a mechanical transmission issue.
