sfort	GMC Jimmy won't start in morning without using starter fluid but is ok till it sits about 8 hours. Then I have to use fluid. 4.3 Jimmy 2wd won't start in morning unless I use starting fluid. Then it will start until it sits for several hours and I have to use starting fluid again. Starter has been replaced, spider injectors replaced. Fuel pressure is up to 51. I think it is supposed to be 62 to get it to start. Could it be the fuel pump or the wiring harness from the fuel pump?
