Four problems related to ignition module have been reported for the 1999 Chevrolet Silverado. The most recently reported issues are listed below.
I drive a 1999 Chevrolet Silverado. On a rainy day trying to do a stop the vehicle lost control luckily there was no other vehicles around. Later I learned that the anti-lock brake system was failing. I learned later that many people with the same vehicle have had many familiar incidents. I have not fixed the problem because gm charges an extremely high price and this is not covered by any type of insurance of warranty not even the dealers.
When they turned off the car it would not turn off. Took car to dealer, and they replaced module at consumer's expense.
Fuel pump, body control module and main computer have been replaced but the vehicle continues to stall while driving or not start at all. Nlm.
Started up the vehicle and was running rough when out on the highway, vehicle just stopped. Had to be towed to the dealer. Had been diagnosed that the #3 and #4 engine cylinders had misfired. Also, replaced the fuel injectors #3 and #4, and spark plugs. Several days later the same problem. This time the #4 engine cylinder again failed. Contaminated fuel, replaced the fuel pump. Contacted dealer and manufacturer.
