ok i was coming home from a camping trip with my trailer. i was passing a slow car (went from 55 to 65) got back over to my lane and there was a bad vibration. i was certain that i had a misfire. i got off the free way and noticed not a place in site for me to work on the truck so i got back on the free way and continued to the next exit the truck got up to 50 mph droped to second then first and said nope im done. pulled her over and spent 300$ to get her back home. i tried to turn it over but all i get is a buzzing and a slight shutter as if it wants to turn over.
any ideas?
i know the truck is used and abused and its about time for a new motor but just checking all my options be for i do so. spent a timing belt chain/belt?

also i had placed a superchip tow/perf program in it about 300mi ago and i used 91.could that have contributed any thing?

 

ive never heard of a timing chain snapping on a 4.6 ir 5.4. it can happen but its rare. thats one good thing about the old 302-351 just pop off the cap see if the rotor spins. says you have 182k are you on original fuel pump?

 

fuel pump is stock

 

Can you hear the fuel pump prime?

 

well im not sure if the winding i hear is the pump. befor the truck died to get some more speed i manually shifted to 1st and the rpms did jump up so i dont think fuel is an issue?

 

Check for pressure at the schrader valve on the fuel rail. If it's there you'll know it. Should spray out really good, so have a rag handy.

 

i do happen to have a fuel pressure guage ill give it a try. any idea what the psi should be?

 

i want to say at least 20 pounds. others will have the exact pressure

 

Going back to your original post under No. 1, your engine wouldn't turn over. Is it now turning? Also, if it is OR when you get it turning over my first rule is to determine if you have an ignition problem OR a fuel delivery problem. You won't get anywhere barking up the wrong tree. If it is turning over there are a few easy ways to determine if your ignition is firing.

 

sounds to me like the alternator crapped out
low volts cause crappy running then no run
no start with low batt solnoid will chatter

No it will not turn over. i only here what i think is the starter. after about 4 sec of trying to turn it over it will shutter just slightly and stop then continue for another 4 sec and do the same thing.

 

did you try to boost or put in a known good batt?

i replaced it about a month ago when it took a crap on me and has been working great. the truck turned over and started much faster untill ...well now.

 

See if head lights are bright = good battery
You don't need a fuel gauge just get a rag and test at the schrader value under hood it looks like a value stem in your tire

 

batt is good im not near my truck right now to check the fuel pressure. has some one had this problem with the fuel pump?
any ideas.
i have my other truck so im in no hurry to get it in the shop which is nice so i can try to trouble shoot it my self with your help.
