i have a 95 dodge anvenger 420a 2.0and it was working fine then one day i heard a loud tapping noise on my way to work i stoped at a light and it died! i tried to start it and it wants to turn over but its not getn enough umph to do it after about the fifth try my battery is dead. any suggestions? please help!

 

check the timing belt ... it might have broke ...

 

ive checke dthe timing belt and the firewall relays as well as the pcm relays they all seem to be working fine when i test the asd relay its at 12.21 when i turn over the engine it drops to 8.5

 

You try hookin a jump box to it and starting it. I can't help but think its the timing belt.

 

Did you check the timimg marks or just look at the belt ???

 

yes the marks line up on the timing belt and ive even put a new one on. but still all it will do is turn over and back fire now. also earlier while i was working on it i heard a humming noise under the hood when i turned over the key in to the on position i listened closely and it was coming from the to computers behind the fuse block under the hood. Is supposed to do that i belive it was coming from the first one looking from the front of the car

 

backfires are normally timing troubles ..
The humming are you sure it's not the fuel pump ???

 

ok thanks for info on the back fire i'll recheck the timing. on the humming noise it is deffenitley the first computer under the hood behind the fuse block what could it be? ive never herd it before and my friend has the same model and his doesnt make any noise

 

humming is normally the fuel pump although it's in the rear , you might be hearing it thru the fuel rail or something since the motor isn't running

 

Can you decribe that humming a lil more. I had a hum/buzzing sound coming from my hood a while back and it wouldn't start. I had a bad positive cable.
