it turns over great but it want fire after . I changed all spark plugs firing coil it ran great for few days and then started skipping and stopped and want start. This all started a month ago when I hit a big pot hole and the truck stopped cold ,i had it towed to garage and the replaced the relay fuel line and wires to gas tank reset the emergency over ride control under dash then it ran fine for 3 weeks .Then started skipping and as I stated replaced spark plugs and coil fuel filer. So there you are.
