    I have a 96 Silverado 5.0. It just cranks when the temp is in the 30's and won't start. When the temp is 50 out, it starts right up. I've checked the fuel pressure with a gauge and its 63 lbs, be it cold or warm out. It has new plugs and wires. The Check Engine light isn't on. I hooked up a scanner and it shows no codes stored. I don't get why it just cranks when its cold, yet fires right up when it 50 degrees out. Any ideas?? Could it be the spider injection is bad? The truck has 178k miles on it. Thanks for your input. I know I'm stumped. I would think that if it starts fine when its 50, it should start fine when its 30 out.
