You might try taking the MAF out and cleaning it with an approved cleaner. The throttle body can be cleaned, but should be done with throttle body cleaner, not carb cleaner. |

I have a 2002 blazer that will not start. It will turn over but not start up. I am getting a fuel pressure of 45, i do not know what it should be at. I am thinking my fuel pump is bad. I replaced one about 3 years ago. Anyone have a suggestion?

About a year ago I noticed a problem with my 97 chevy blazer. The check gages light was coming on every now and then and sometimes it would cut off while I was at a light or stop sign. Then one day after I had driven the car all day, I came home and parked for about an hour. When I went to start the car it acted as if it wanted to start but did'nt. Six months prior to this I had gotten a new fuel pump, radiator, battery, and the spider and fuel valves changed. The fuel pump was from auto zone. The vechile has been sitting up for maybe a year and a half and I miss my truck. I did not have the money to get it fixed being that five to six months prior to the break down I had spent around $1,000.00 to get those things that I mentioned fixed. Can someone please help me try to figure out what is wrong? Any suggestions would help. I miss my truck!

Replying to: yruffin (Aug 09, 2009 1:45 pm) The bad news is that it costs 60-70 bucks! I have seen CPS failure occur two different ways. One is just driving along and boom, engine dies. If you try and restart, no-worky, but if you turn the key to off, wait a few seconds, then try to start the car it will fire right up. The other failure mode I have seen is an engine shutdown at high RPM, and coming back online when the speed slows down, sort of like hitting a governor. The intermittent failure may or may not set a code. The high RPM failure will only set a code if it occurs three times within an operating cycle. That means you start the car and get it to occur three times before turning the car off. I would suggest getting someone with a code reader to check for stored codes. You can spend a lot of money on sensors before you hit the right one. |
