Hello, well I am a chevy guy. Firstvehicle was a 79 short box low-rider(retroed with a buick 455?). Tried other trucks just didn't work out...have a family now and went to a 1994 3/4 ton ext. cab!I have had this truck for about three yrs. and it has been great. It has 160,000 miles and just a couple days ago start dying intermittenty???? No warning, no particular time.The tach just drops but lights and stuff seem to stay on.. I let it sit or put it in nuetral(if I'm driving when it does it)and wait 0-60 sec. and she fires right up and will die in 5 sec or 5 min or 5 miles never know???? Itstarted lastSaturday and seems to be getting more frequent. I just drove it 4 miles before it did it. I started it after coasting for 20 sec. and then drove another 2 miles no problem?????? Help!!!!!! Thanks for anything!

 

well,ya gotta find out what your missing...fuel,spark,or injector pulses...fuel is most likely....the fuel pressure needs to be checked while she's dead.
sounds like a pump...but warning...don't put in a cheapie pump if thats it...a/c delco or nothing.
keep us posted!

 

Thank you for your time. I will have the pressure tested and look into a fuel pump. I have heard horror stories about the fuel pump......oh well let the games begin!! Thanks again
