I am tackling the same thing on a 1994 Ford Arerostar van. I think that the wire from the fuel pump relay is also connected to the Powertrain Control Module. ( The book makes mention that that the PCM controls the fuel pump! ) If this is true then the PCM may place a "LOW" on that line if it wants the pump off, preventing the relay to pass the voltage to the initeria switch and then the pump??? ( I'll let you let me know? )

How do you replace the distributor cap on a 1999 Suburban?

If it is a 1999 Suburban with a 350 there are two screws. Remove all your wires first. Take a T15 Torx driver and take them out. The cap should be loose and you can use light pressure and pull straight up. Be sure not to move the distributor shaft relative to the engine. This is a net timing application and you will have to take it to the dealer to have it timed.

1987 suburban stopped running now has no spark replaced coil cap rotor electronic ignition module in distributor?

I'm not sure I understand your question. The ignition module is suspect in this case and yes, it's under the distributor cap. You may also want to replace the distributor cap and rotor while your at it, they're cheap parts and hair-line cracks in a distributor cap can be hard to detect. If all of these fail I'd look at replacing the coil and coil wire to the distributor.
