Help identify this sound (Page 1/1) tjoudrey NOV 13, 08:35 PM Here is a video for reference. https://photos.app.goo.gl/r19po8xR6ZW1ew9G6 I have been troubleshooting electrical issues on my 85GT and came accross this whirring sound accompanied while clicking in the front end uppon connecting the battery. After allowing it to sit for a moment the whirring noise has not reoccurred. One concern I have is that there is not any coolant in the motor at current and that the water pump broke or something which is why the noise stopped. Would anyone happen top know what this noise is? Thanks. Patrick NOV 13, 08:41 PM Without even watching/listening to your video, I'd suspect a headlight motor. tjoudrey NOV 13, 08:45 PM I should have also mentioned the whirring sound appears to be coming from the engine bay, where the clicking was the front end olejoedad NOV 13, 08:55 PM Cannot tell anything from the video.... tjoudrey NOV 13, 08:57 PM I have managed to cause it to reoccur. I have absolutely no Idea what this sound could be. Here is a video of a second instance https://photos.app.goo.gl/JEzm8bU7qq86gAyM9 tjoudrey NOV 13, 09:34 PM SOLUTION: I figured out that the sound is the fuel pump. Now to figure out why the fuel pump is stuck on cvxjet NOV 13, 09:43 PM Clicking sound up front would probably be one of the headlight motors.....A bad Oil pressure sensor can make the fuel pump stay on....I converted my 85 to an 88 OPS...Much more dependable- no oil leaks either! To do the conversion, you need a connector that matches the late model sensor and some waterproof splices...... FX NOV 14, 08:49 AM Yes, I think cvxjet nailed it. I had this happen to me. Replaced the oil pressure sender, and problem solved...
