Ive been having a heck of a time. Got this truck..already had new alternator, battery. started just dying going along, pull over an wait a minute fires right back up. took it to shop..they said coil was bad..replaced that..same problem..they replaced fuel pump and filter...same problem. then it decided it wouldnt run at all. tired of giving them money. read this forum and replaced relay. fired right up. fuel pump runs all the time now when key is on. Could get 35mph an then starts coughing an sputtering, let off gas an smooths out. Now wont start again. Replaced spark plugs and wires, still only 35mph maybe. now wont start again. will start if i put gas in carb. fuel pump runs all the time when key is on. Havent found anywhere that the gas is going. What now???
