Ok, this might be a long post but I want to give all the details I can.

03 Elantra 2.0 DOHC auto with 102,000 miles. Started knocking, rod knock. I figured Id go ahead and drive it to the house, knock was bad but still driveable. I start on the 10 mile trip, made it 7 miles and it got hot and started lossing power, finally died. I let it sit overnight and she ran fine again minus the knock. Started driving back to the house again, 2 miles in it just died. Spins over fine still, not getting spark. Not firing at all. Ive searched and cant come up with anything thats a common issue on these cars for it not firing. Check engne light never came on either. Anyone got an idea as to where to start? I need to get it back running/firing so I can fix the rod bearing.

 

this sounds like what happened to me. i'll bet its one of the bigger fuses under the hood. pop your hood, fine the fuse box, check or test all the fuses. the fuses cost somewhere between 20-50 depending on which one, and if you can at least eliminate that as a problem, you can move on to something else. but this happened to me, couldnt' figure it out, and once i brought it to a mechanic, it cost me $200+ for all the b/s, all for a $30 fuse
