Hello All, I have an ongoing issue I was hoping to get a few opinions on. A few weeks ago my truck started to gradually spudder when I was cruising with the RPMs jumping very slightly when it did. I did not notice it being related to transmission as it was shifting just fine so I figured ignition/timing. The check engine light came on with the error codes p0016 and p0300, camshaft/crankshaft misalignment and multiple misfires, respectively. I needed some brake work done anyway so I took it in to get serviced and they replaced the distributor rotor, cap, wires, sensor and all the coil packs. It worked fine for about a day and then the light came on. I've been working nights on a turnaround the last 2 months and just do not have time to take it in so I waited. About three days after the truck finally just died on the way home. It flashed low oil pressure/low oil level and the pressure dropped to zero as it was dying. I checked all the fluids and for leaks, everything was fine and where it should be. I had it towed to firestone (only thing that was open on the weekend). They quoted me $1300 for a new ECM and new distributor install. My truck is only work $2500-3000 and I'm coming up on paying that for repairs after the last round and this one. They said my ECM was sending commands but not receiving any and the distributor was not sending anything to the ECM. So my questions, the ECM I can see as being a potential for replacement, but the distributor seems like it would have more tell-tale signs if the gear drive was cracked or worn. They also did not mention anything about the ICM or the timing chain, which to me seem like the most likely culprits here. I really do not want to fork over $1300 only to find out my timing chain is stretched or the gears worn and have to fork over another grand. I'm going in tomorrow to inquire, but any help here would be greatly appreciated. Thank you for your time.

I seriously need help locating the crankshaft sensor on my 2004 Silverado 2500hd diesel. I have been looking for it for 2 days now and I cant find anything on internet to point me to the exact location. please please help..

So i was trying to take my boys out camping and while driving my truck died like the alternator had quit and I ran the battery down. Got off the road, no problem, long story short, replaced the alternator and there was a clunk/scrape sound when starting it up. Didn't like the noise so I had it towed home. The sound seems to be localized in the bell housing so I took off the inspection cover and thought I would find a cracked flexplate. I can't see any obvious cracks in the flexplate, disconnected it from the torque converter, noise is still there, the flexplate appears to wobble when running, not sure where to go from here... I have attached a couple videos of it running so you can see and hear the noise. Any input would be very appreciated. I can do the flexplate but if it's lower end issues I don't have the time and garage space to tear into it as I am PCS across the country soon. Thanks in advance for your thoughts.

Looking to replace my crankshaft pulley and wanted to know should i op out and buy a performance one or just stick with factory and also are they hard to replace. Thanks for any help 1991 GMC Sierra C1500 5.7 Monster transmission.

I have a 2006 Sierra, 4.8 litre. It recently developed a squel, that sounds like a belt squel. I checked the belts, and they are fine. I removed all the belts and started the truck, and it still makes the noise, the only thing turning is the crankshaft balancer. So, I've pretty much decided that the crankshaft balancer pulley has to be the problem. Would any of you have any other thoughts on possible causes. My Dad seems to think that it could have something to do with the timing chain. I'm really hoping that it's only the balancer pulley. Thoughts?
