I am helping a friend who has a 97 ram 1500 5.2 liter. I replaced the water pump, the truck ran yesterday, but wont start now. I had to loosen the ac bracket and the alternator to get to the small hose that goes from the pump to the block. the only thing I unhooked was the ground wire from the alternator which I re-grounded. When you crank the truck now it backfires out the throttle body and the fan will spin backwards when you let go of the key. Any Ideas?

I, too, believed it was a tapping in the engine.
If it is exhaust Manifold bolts - Which it proably is. Holding the manifold to the engine is 4 studs with nuts and 4 bolts - If I remember correctly. The exhaust shield is held on by the 4 nuts onto the 4 studs. IN my case, 2 of the 4 studs broke , where the nut holds on the shield and the exhaust shield was hanging partly off. If this happens, then the manifold can pull away from the head at the location of the broken stud. I could also see, near where the broken stud was, black soot that was escaping the manifold.
The replacement is easy, atleast for me. All of the studs and bolts removed easily.

I just had to replace two on my Grand Cherokee (4.7) rear two on driver's side. Common as all hell. Was lucky the heads broke off and there was enough threads exposed to grab onto, actually turned out by hand. And yes, this causes the manifold to slap against the engine and sounds JUST like a bad lifter...

Well the noise is gone for now actually, I looked at the manifold bolts and i tried tightening them, but they were all rock solid.....I think it just took a good half a tank for the seafoam to work it's magic......We'll see how long it lasts though...
In other news though, my buddy's 2000ish Chevy 1500 is having exhaust problems, so here's to that! I get to help him out in my spare time all week. Should be easy to fix though, sounds like its just a leak.
