My truck is a 96 psd. I had to take out the filter bowl and remove the fpr to fix a fuel leak. I put every thing back together and It starts fine. I let it sit idle for 20 min to check for leaks. All is good.I hop in to go fill the tanks up and back out of the carport and the truck dies. I turned the key back on and the wts does not come up. I checked the fuses and the number 13 is out under the hood. I read somewhere on here that the fuel heater could be the problem. I unplugged the fuel heater and replaced the fuse and the truck will turn over but not start. The wts light did come on after changing the fuse. Any advice would be great.
