Why My Truck won't start?

Make sure battery has a full charge and battery connections all good. How long since a tune-up? If it cranks good but won't start, have a helper crank it while you check for spark at the plugs--use a gage and check proper fuel pressure--check fuel injector pulse. Check applicable trouble codes? those are the basic checks, in my opinion. If your missing everything, spark--fuel--injector pulse, look for an rpm signal, that should come come from crank sensor. Don't replace anything unless your testing points in that direction. good luck
