#121 of 142 replaced fuel pump now rough idle high fuel pressure by johnyboy1 Oct 03, 2008 (3:40 pm)
hi,i have a 1999 blazer with 4.3L engine.the fuel pump went bad so i waited about 2 weeks then replaced it when i had the time.now the engine runs very rough and the exhaust is black and smells very sulfery.after driving it awhile i got the service engine light, the code reader shows p1133 and p1153.when i put a pressure gauge on the fuel rail test port it's reading 80-90 psi well above the 60-66 psi it should read. before the fuel pump went bad and i replaced it the car ran perfect.the manual i have for the car does not tell me what these odb codes mean. any help or ideas would be greatly appreciated

Replying to: bigt442 (May 22, 2008 11:26 am) The water leak shouldnt cause a vacum leak although it may! But the code lean on bank one tells me that the o2 sensor is bad, also check to make sure the firing order is right as well! The code says the o2 sensor in bank one is bad which means the sensor befor the cat. try replacing that one. there should only be 2 of them on that model

97 GMC Jimmy with a V6 Vortec, motor was bought from Advance and has around 40000 miles. I didn't put the motor in, it was already installed when I bought it. Hope someone can help me with this miss problem, I will try to explain it the best that I can. First off, new plugs, new plug wires, new coil pack, fuel filter and air filter. Catalytic converter has been removed. No Check engine light is on. The vehicle starts perfect and idles perfect, but when you go up a hill it sometimes has a bad hesitation like you are letting off the fuel back and forth, give it more gas and it quits. Then sometimes on flat ground at 55 mph it does the same thing. Sometimes I can pull into a parking lot at 3 mph or at an idle and the motor has a violent stutter to it. That has only happened twice. So can anyone enlighten me on this subject?? Replies to this message: sealteam8 (Oct 09, 2008 8:04 am) bowtie468443 (Oct 10, 2008 9:28 am)

Replying to: tommyj2 (Oct 08, 2008 7:21 pm) Actuall it is not the motor. my moms blazer is doing the same thing and it is a factory gm motor. I am trying to track down that problem this week if i figure it out i will post another message to this problem. Replies to this message: bowtie468443 (Oct 10, 2008 9:28 am)

Replying to: sealteam8 (Oct 09, 2008 8:04 am) In some older GM transmissions there was a problem with electronic solenoids sticking and not allowing the trans. to downshift out of lockup. This may be part of your problem

Replying to: nightauditor2 (Dec 26, 2008 1:55 am) It could be a number of things. Like a fuel filter or fuel pump. or ignition coil. Check to see if you have the three basic needs. fuel, spark, and of course you will have exhaust... The spark should be bright blue. not orange! and fuel pressure should be around 62 pounds with the key on and engine off. and 60 pounds with the key on and the engine running. let me know!
#130 of 142 help w/ blazer!!! by kalani1 Dec 28, 2008 (5:40 pm)
My car wont start. It turns over but thats it. Not the battery as I just replaced it and like I said it turns over. I was snowed in for 10 days and 2 days ago tried to get out-my car was fine and it started but ice and snow was too thick so all it did was spin the tires but I think it affected the engine because e tried for about an hour and only got 4ft!!!!!! The car was missing alot about 2 weeks ago and suddenly stopped. I have been told it is the fuel filter or pump??? I am new here and will have to get it towed in the morning but also dont want to get taken advantage of. Any ideas??
