Pull the dist. cap and make sure the rotor has no side to side
The top bushing wears out and the magnet hits the pickup.
Maybe ,my best thought.

SOURCE: 98 GMC k2500 7.4L Rouch Idle
TRY THIS BEFORE U SPEND ANYMORE MONEY N PARTS.
Here is the common cause of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

did you spray the maf sensor or intake hole ?if you didnt spray maf then probly not! have some one turn the key why you listen in the fill gas hole for pump noise ? sould here somthing for 2 seconds at least besure you ear is there before key is turned , also check you ecu fuse to see if it may be blown .? also you could try unhooking battery cable for 20 minutes neg side only then rehook it and try to start it! good luck

This could be a number of things but i think that your problem sounds like a vacuum leak or an EGR problem. Try listening for leaks and try un-plugging the EGR solenoid valve one time.

The oil pump is in the oil pan and needs to be dropped and being a 4WD you also need to drop the front axle pumpkin to remove the oil pan and replace all the gasket needed. Start with the easy and replace the oil pressure sending unit, it's on the back of the engine to the passenger side of the distributor. You can go to Auto Zone and pick up a new Oil sending unit, just make sure your get the right one, "Sending Unit" Looks the same are the oil pressure sensor but the unit reads the pressure, the other just signal a light to go on and off. It's an easy fix like replacing a spark plug.
