2001 Chevrolet Blazer Repair Question
Replaced fuel pump may 18th, now it wont start half the time and acts like its the fuel pump again, read details PLZZZ
did he replace the connector which is a common failure?? was it a complete unit or just the pump??
he should stop clearing the engine light and let someone look at the freeze frame data to help determine the failed system clearing the light does nothing as the problem will not fix itself.
It was a complete unit and I been searching online the last few hrs and seen several times where the connector was mentioned as well. I know all he replaced was the fuel pump unit and nothing more so I will for sure mention this to him in the morning. And as for clearing the engine light, I asked two different certified mechanics if we should replace the O2 sensor that the code referred to and both of them said it wouldnt really cause any issues if it was left faulty and we could clear it using the code reader thing. And what is the freeze frame data? Ive never heard of that. And there has never been a problem with the blazer til the fuel pump went bad so that makes me think the issue now is somehow related. So thanks for the info and sorry I have more questions :)
Also...I wanted to ask what the chances are that the new fuel pump could be faulty? Ive heard the fuel pumps made, especially for the 2dr models as we have, arent considered all that great and getting a faulty one is actually quite common.
freeze frame data is critical data needed by a tech to look at readings at the time of the failure. it gives him a good view of where the problem may be.
cetified or not, never a good idea to clear light till the problem is actually fixed. code numbers never identify a bad part, just a failed system.
problems dont seem to be related. i need a code number to see what they are guessing about.
the connector must be replaced as it fails more than the pump itself.
yes, the new pump could be bad. a fuel pump pressure test will verify that result.
ok after talkin to him and us goin out and seeing what we could do...we know that there is no fuel pressure cause when he found the schrader valve there was no fuel that squirted out of it like it would if it had enuf pressure. we can hear the spider make somewhat of a clicking sound and i no that the fuel pump works so i assume that it is getting power. besides a bad fuel pump what could cause the fuel system to lose fuel pressure?
no, the fuel pump is not working. if there is no fuel at the schraeder valve. start at the beginning. you need to see if the is any power to that connector and see if it is on both sides. if it is and the ground is good, then you have a failed fuel pump.
there was a lil bit of gas that did come out but not what i no is required....so gas is present. so does that mean the fuel pump is working cause if it wasnt then shouldnt there be absolutely no fuel in the shrader valve at all? and the blazer fan fine with no problems for about 2.5-3 wks after the new fuel pump was installed so we know that it did work properly and the fuel system was functioning the way it should. or am i just tryin to convince myself that its not the pump itself again cause it was such a hassle? :)
you are trying to convince your self of the real issue.
