I have a 1998 Chevrolet c1500 2wd with a 5.7 vortec engine. Several months ago I had crankshaft replaced. Truck sat in shop for a while and when I got it back it wouldnt run. I figured it was bad guess because no codes thrown. Recently I drained the whole gas tank and put nerw gas in, and finally got it to run. Engine ran good, I drove it around the block. I cranked it daily for a couple minutes each day afterwards and it cranked fine. I went out there today and now it wont crank, so I thought maybe I was out of gas. Put new gas in tank and still wont start and Im getting a p0327 code, I never had a code before. I have around 57 psi fuel pressure at the engine. Starting fluid wont start it eiither and I believe I have spark. What could be the problem?

Code 0327 is knock sensor circuit with low voltage but that shouldn't stop truck from running or starting. Fuel pressure should be 60-66psi minimum so that may be your problem. But check for spark at plugs as well as it maybe one of the basic ignition items.
