Ok so I have recently picked up an 88 k5 with a 350 tbi and have been working on it, after finally getting it running and on the road it has developed a hard start usually its difficult to start in the mornings but even after it has ran and been driven around and its warmed still don't want to start easy, sometimes even having to spray starting fluid down the tb to get it to start, was told by the previous owner and actually seen receipts on a new fuel pump and filter, also was told the ignition module was replaced, but one thing is that the previous owner had for some reason replaced the stock fuel line with rubber hose and hose clamps from the fuel filter to the tb and was thinking maybe not holding pressure? But when it runs it runs good, no misses and good power, even changed injectirs injectors and rebuilt tb so this has got me totally stumped? and any help on the situation would be greatly appreciated
