The main reason I think it is broken is when you start it the starter just sounds like a high speed drill. There is no indication that the pistons are trying to compress and ignite and only heard one or two fairly loud oomphs. Nothing like it sounds like normally. If it was the timing chain shouldn't it make rattling sounds or something. Just brrrrrrrrrr like an electric drill.
I asked this question before and given the description below many suggested it was a defunct fuel pump. Sounds reasonable except for the starting symptoms.
This happened to my 18 yo son. Vehicle is 2001 2 wheel drive, 4.0L Grand Cherokee with 150K miles. His description is thus.
I exited off the freeway. First i noticed it wasn't accelerating as much as it should. The motor was reving normally but no acceleration. Then the rpm slowed way down. The engine was so on though. Then the power steering stopped and as my car stopped so did the engine.
It will not start again. A friend suggested it was a broken timing chain since it sounds like the starter is turning faster and there is zero indication the engine is trying to catch. But if the timing chain broke wouldn't it had made more gnarly noises and the engine just die immediately?
If not timing chain what else would produce the results I have?
Is there a simple way to check the timing belt without tearing it all apart?
