Regarding cpi failure: Check "O" ring behind fuel pressure regulator(rough idle, loss of power, reduced gas mileage; fuel in manifold; when testing fuel pressure it drops almost instantly when fuel pump shuts off) pretty easy to mistake for a cpi failure.

Consumer complained about a fuel injection system problem. Consumer took the vehicle to the dealer and received many different stories of remedy. Consumer asked the dealer to check the fuel tank, and the dealer refused to check it. Then, consumer contacted the manufacturer, and was told by the manufacturer that dealerships were independently owned, and there was nothing they could do.

Consumer stated that while driving and without warning, the egr valve failed, which caused the brakes to fail. Dealer notified. The mixing with the fuel was the biggest problem. (when there was carbon build up in the egr valve, it would leave it open and caused no vacuum hard pedal and brake failure. When it rained or was cold the truck ran rough. The service light came on when the vehicle had run rough more than once, noise was present and there was a smell of burnt wires and the ignition switch was replaced, the brake pedal seemed soft on more than one occasion and the master cylinder and other brake components were replaced to try and solve the problem, the cd player had not worked since the ignition switch was changed, the rear windshield wipers had become inoperative, a noise would occur when turning but was not duplicated, and the muffler tail pipe had fallen off and rusted due to carbon build-up. The egr valve was cleaned but the problem persisted. The mechanic stated that in order to perform a proper job, the excessive carbon build up in the upper and lower intake manifold which effected the egr pendel, and the 02 sensor could cause a problem with the exhaust system, catalytic converter, fuel pump, the brakes, etc. The brakes squeaked, there were no dash lights, no air conditioning, and no 4-wheel drive. The fuel injections needed to be checked, and there were two recall stickers on the engine. The rear wiper motor, fuel injectors and brakes were replaced.

We have had repeated problems with this vehicle from approximately 4000 and going forward. The first indication of problems with electrical was when the emergency flashers were used the first time and it blew the electrical system at approximately 4000 miles we had owned the Blazer less than 6 months at this time. We have had service engine check light indicator problems repeatedly and was told every time but 1 that it was "nothing" and later we have problems that are conveniently not covered under the warranty any more. The soft plugs blew in the engine in 9-1999 and we were told by the garage that repaired this that he had seen this before... the antifreeze used deteriorates the plugs and they eventually leak and the engine overheats. The GM dealer that we took the Blazer to on this occasions for a second opinion 11-2000 --this dealer had another 1995 Blazer in the shop at the same time with the exact same problem. I thought this was odd for a town of 25,000 people and of course the 800 line to GM customer services advised me that it wan't anything that could be covered. We also had the leather seat replaced on driver side 2 times but continue to have problems with leather splitting and of course this is not covered.. all we are able to get from GM is the answer "no" whenever we feel that something should be covered... we have put over $2000 in repairs in the engine and wipers and fuel injection system in the past from 9-1999 thru 11 28 2000.... and the problems continues.. the service engine soon lifht comes on and the air bag light goes off and on and stay S on for long periods of time... and of course when I called last week on the air bag... lite it was.

- Riverside, NJ, USA

5 egr vlaves replaced, one every year. The cooling sysyem has failed having to be replaced and flushed twice in the last thirteen months and is still making the same noise we have heard for the last year and a half. The fuel injectors have been replaced twice in the last fourteen months ! the rotors have been resurfaced twice, replaced once and we still need to replace the pads every 8-12 months, regardless of milage. The extended warranty is up on this vehicle in one year. My question to Chevrolet is who will incur these costs that both GM and the dealer admitted to being product problems !!!!

Egr valve replaced. Cost over $400. Chevy only recalled 96 or newer and there has been over 60 complaints logged about this. When is there going to be a recall on the egr valve. I now need to replace it again. I have also complained to Chevy regarding my brakes. I have had to replace my brakes every 6 months since I bought my car. The dealer told me brakes are not covered under warranty, that it is normal wear and tear of the vehicle. I have also been having problems with the fuel injection system. Other year vehicle have recalled these problems but not for the 1995 Blazer.
