Hey everyone and thanks in advance for helping. I have a couple of serious issues on my surburban. 2001 1500 5.3 2wd body lift with 35s w/ 140,000mls. Symptoms: No start if it sits for more than a day when you turn it over it takes a few trys to start when it does crank it takes like 1-2 secs for the oil pressure to rise to operating pressure idles poorly, if i stop at a light it acts like its running out of fuel and a few times has actually shut off. abs pump whines very bad and throws codes I have had issues with this truck for 4 years now on and off. Replaced the fuel filter probably 6 times and it isnt dirty but everytime i have done it, it has seemed to help for a little with the performance of the motor. Now it just doesnt help at all. Pull the ABS pump fuse so i run it with no ABS at all (no issues either). My main problem is the starting part. I have put new batteries in it and a new alternator. I went to my uncles mechanical shop and he helped me kinda of diagnose or track down where the issue might be coming from. We hooked checked the draw on the battery with the key off doors shut and hood light disconnected. It has a 6 volt draw which is pretty steep. With the VAC machine hooked up (checks the draw) we starting unplugging things; starter, alternator, fuel pump, a/c compressor and a few other things. Started pulling the fuses one by one- nothing. We took the fuse panel under the hood apart and started disconnecting the actual harness from the fuse panel and the gauge dropped to no draw. Take a look at the actual fuses that go to this separate harness and its the interior accessories that are causing a draw, or so we think. So my question is has anyone had any of these issues before??!! Is there somewhere i should look first before i have to take all the interior panels out. I need some serious professional help. I can pull a transmission motor install change a water pump whatever but electrical issues stump me. My uncle cant afford to help me anymore being too busy (what an ass i know but what can i do). So i have it back at my house so im on my own. Thanks for the help in advance!
