Two problems related to fuel injection have been reported for the 2001 Chevrolet Blazer. The most recently reported issues are listed below.
The events that lead up to the failure of the fuel injection system equipped on my 2001 Chevrolet Blazer are in correlation to the manufacturers knowledge of having installed a defective product on 1996 - 2002 vehicles with sequential central port injection. After having to deal with the problem of figuring out how to fix the code p0300( random cylinder misfire) on my 01 Blazer, I realized it was time to get more help from outside sources who have experienced similar issues with their vehicles. I've done enough research to know now that after eight years of owning the truck and dumping money into unnecessary repairs that Chevrolet should fix this problem at their cost since they knew about it after being investigated by the California epa research division on air pollution back in 2003. They found the scpi system installed on models between 1996 and 2002 to be faulty creating a problem with the start up of many suvs which lead to emissions failure. I'm researching this now because I've finally connected the dots and realize that Chevrolet knew about this problem many years ago and they cut a deal with the epa to extend the warranty coverage on such vehicles for 10 years or 200k miles in an attempt to satisfy California regulations. Well, what about the rest of the united states and how we deal with air pollution. I thought gm and Chevrolet wanted to be the company that would set the example in "going green" for our planet. It doesn't make sense until you realize the amount of money that they save by not having to replace faulty fuel systems on older model vehicles which happen to be driven by people who are a lot smarter than they think. I've taken the liberty of filing my claim with chevy to resolve this issue. I'm hoping that this complaint along with valuable information on the internet as well as your web site can inform others of their rights and how we should all be covered under warranty to fix the problem permanently. Thank you for your time.
Replaced air filter for fuel injection system, fuse. Pump was full of water. Replaced air pump silenoid, full of water. Reroute hose to pump. Was told my dealership this was the 4th replacement of this type on same type of vehicle in 2 days.
