97 suburban- fuel pump changed 5 times, fuse changed many times, Ignition regulator changed 6 times. Now the fuel pump will not come on and it is brand new all was checked and it is getting electrical spark. Brand new battery installed two weeks ago. New starter was installed less than a month ago. The vehicle when it is running will start right up with the new battery. This last time it ran good no problem starting, no cutting out parked it and would not start. The fuel pump was less than 1 week going in. Parked the car after driving it 60 miles and it would not start. Fuel pump was taken out and found the screen had come off. It was replaced with a brand new fuel pump. Now we are not getting any fire back to the fuel pump. The little fuse in the front of the engine was replaced. We are at a loss as to what to do anymore. This is very frustrating. The last year has been hell with fuel pumps and regulators. Does anyone have any idea what is wrong? This is an awesome vehicle and has never given me any grief until a year ago.
As you say you changed your fuel pump .take it in the fuel tank. common trouble when people do this .is you have a locking ring to lock the sender in place .lot of people think it is fitted correctly when in fact it is not .so check your work when doing this .as you will get an air leak from your sender in the tank if not done right. so the car will start .then may run for about 1 mile then stop.
Try the fuel sending unit

Okay there should be a plug on there make sure it is pluged in all the way. If you have someone to help you pull one of the spark plugs out plug it in to the wire (Do Not Hold Wire with Bear Hands) use insulated pliers.try to start car if you don't see a spark from plug then it means that the coil pack is bad. If it does spark then it is possible thet it may be a fuel problem.

Bad EGR valve comes to mind here. Assuming the plugs are good, the EGR valve woiuld be what I'd look at.

My truck did this after I replaced the fuel pump. Turned out to Fuel Pressure Regulator. It would crank and crank but never start. It's located underneath the black plastic manifold on the side of the injectors.

Did you reset the inertia switch that shuts pump down in case of collision?

You will need to figure out if you have spark to the plugs, and if not- if you have voltage to the coil to proceed.
