Mechanic Job in Mesa, Arizona

I have a 1998 Dodge Ram 1500 5.9L v8 that suddenly refuses to start, in desperate need of a diagnostic. It has a strong, normal sounding crank and was driving great. All the fuses are good, had the alternator bench tested. The fuel pump is heard when key is turned. It has spark, used an inline tester with the old plugs and wires. I still replaced the plugs and wires, as well as the crankshaft position sensor. I only need to know what the problem is and i can do the repairs myself. Just cannot find the cause. Money is tight, but if I don't get this running I will beout offajob. We can come to a fair price for both ends.
