Hello. I have a 96 Bronco with a 5.8 that sat for over 5 years. Ran before sitting. Recently wanted to get it running again and noticed no prime on the fuel pump when trying to start. Dropped the tank and replaced pump and sending unit, after draining out all old gas and cleaning the tank. Replaced fuel filter also. Added 5 gallons of new gas and she fired right up! We drove it around the neighborhood with no issues, maybe 5 miles max. It sat for a week, then drove it again maybe 3 miles to family's house. It ran fine again. Shut it off there and talked for a while, then went to start and it cranks, bit won't start. I didn't hear the fuel pump prime, so I suspected I got a junk pump. Replaced fuel pump again, and still no start. After a little bit of troubleshooting, I pulled the fuel pump relay and tested the negative trigger. I get the trigger when the key is first turned on (prime), but no trigger when cranking. From what I've read, the ECM needs to see over 200 rpm to send this signal while cranking and running? Where is this signal coming from? Is it something to do with the ignition/distributor? Thanks for any and all help.
