454 will not start
Hi My name is Zack and I have a 1994 GMC suburban "454" and it will not start. I'm getting fuel and spark, I replaced the fuel filter, plugs, plug wires, And the ignition control module, checked compression,,,, everything seems good but still will not start? Does anybody know if this motor has a crank shaft sensor? If so where is it's location? I dont know what else it could be? I was driving to work when this happend, I made it to work it was just running a little rough, went out on my lunch and would not start.... I'm lost

Fuel pump maybe? Do you have fuel pressure? can you hear the pump prime?
How many miles?
