    04 Suburban Cluster Issue

    I've mentioned it before in this post. It's a brand new Delphi pump. I've been in the parts business and working on vehicles for over 14 years...never had a single Delphi bad out of the box. It's not the pump. There is a PCM update to fix the issue of the fuel gauge not reading fully full...so...

    Interior Dimming Issue 04 Burb

    I couldn't find a thread on this exact problem, or a solution. My 04 Suburban seems to have an issue with the cluster and the rearview mirror screens being dim when it's sunny out. At night it's just fine. Cluster is new, and the company tested it multiple times and sent me photos of the DIC...

    2004 Suburban PCM/Fuel Level Problem

    Did you not read the whole thread? The cluster is NEW. Purchased from ISS which is one of the best, they are the ones who started rebuilding them for GM back in the day. They have a contract with GM. It's not the cluster I can promise you that. As someone had previously mentioned here, it...

    2004 Suburban PCM/Fuel Level Problem

    My cluster is from ISS. They are the ones who started rebuilding GM clusters many years ago. GM was sending them to the dump when iss started having them send them to them to rebuild...so I doubt they'd let it go with the needle in the wrong spot... especially two in a row because the first one...

    2004 Suburban PCM/Fuel Level Problem

    Yeah I'm looking into one. But either the dealer or a local shop with the proper software can flash the PCM to my truck and apply the updates at the same time.

    2004 Suburban PCM/Fuel Level Problem

    Right I know what your saying. I was just saying the PCM in my truck is not the original one and still wears the original vin of the other truck. Because it needs flashed. And here's what searching my vin on tis2web shows.

    2004 Suburban PCM/Fuel Level Problem

    Mine is an FG0811. Mines a 31 gallon tank. And I'm leaning towards it needing flashed because it's just a junkyard PCM from an 04 Suburban with the same rpo codes so it works but I know it needs flashed.

    2004 Suburban PCM/Fuel Level Problem

    Yeah I'm not dropping the tank again lol. Especially with a full tank. I know new can be bad...but in my 14 years of working on cars and in parts I've never seen a Delphi bad out of the box. I don't know if I mentioned to you, but the issue is the PCM is reading empty via the values...while...

    2004 Suburban PCM/Fuel Level Problem

    Hey strutaeng, I've done more testing now that I know how to properly read ohms. Never had to before in my life surprisingly. Gauge is sitting couple notches under the full mark. Here's my readings: 238 ohms 2.46 volts According to the chart, that reads empty with the low fuel indicator on...

    2004 Suburban PCM/Fuel Level Problem

    Fless, I'm outside currently testing ohm reading and voltage reading. Remember the tank is full. I let it click off and stopped. I know overfilling is bad. Here's my ohm reading. 238 ohms Voltage reading 2.46v. I checked this directly at the PCM and at connector C152 under the fuse box...

    2004 Suburban PCM/Fuel Level Problem

    Also, I've read that the PCM relearns after about 150 miles of driving...we drove about 180 miles on the gas truck PCM. And I've only driven about 15 miles since putting the correct PCM in. So, is that part of the problem? Some people were saying you can have the key on and remove the two...

    2004 Suburban PCM/Fuel Level Problem

    Voltage reading at the wire going to the PCM is what I'm checking. Direct from the service manual. Obviously there's an issue with the gauge reading. Tank is dead full. Voltage I just got was 2.51v. According to the service manual, that is "Low Fuel Indicator On" or "E"...which, the gas truck...

    2004 Suburban PCM/Fuel Level Problem

    I put it above, but it's a Delphi. All I use for GM. Never had one issue in all the 14 years I've been working on cars and working in parts. Never have I seen a Delphi pump fail. Not sure the one in my truck was bad either. It was a Delphi too. Part number is FG0811. For the 2004 VIN Z Flex...

    2004 Suburban PCM/Fuel Level Problem

    Alright so I just went and filled it up, and it won't go up past full where it should be. And when I got home from my short drive it went down a bit more between full and 3/4. I'll try and attach a picture of the gauge right when I filled it up. It won't go up further than that. I know that the...
