Check gauges light comes on and the oil pressure goes to zero at idle
I have a 2003 Trailblazer. At idle the check gauges light comes on and the oil pressure
goes to zero. It is not making any noises at all. I checked the oil and it is full. It does not
seem to interfere with the way the truck drives.The oil pressure goes up when I step on
the gas and stays where it is supposed to.
no fuel pressure a low rpm- stop! Check Engine light- stop!
Those early models had issues with the cluster head and the motors that move the needles to their proper reading. No help from GM for earlier models. You can find a cluster repair on EBay, very reasonable considering GM charges about $500 buck for a new cluster. Don't jump on the first guy you find or the cheapest. Read through them and look for someone with a lot of experience and guarantees. There is a guy that explains every possible thing you could ask. Good luck
