R&R fuel pump in 93 Jeep Grand Cherokee 5.2

Asked by Mountainboy7267 Jan 30, 2019 at 07:46 PM about the 1993 Jeep Grand Cherokee STD 4WD

Question type: Maintenance & Repair

Our fuel pump in our 93 Jeep Grand Cherokee 5.2
went out due to no fuel pressure so I changed it
out today. We have fire and fuel but it still won't
start.  Replaced the ecm a few weeks ago due to
no fire and it has been running fine until the fuel
pump issue. Any ideas?

How much power should be coming to the injectors? Is it 12 volts or something less. As for the fuel pressure regulator, what am I looming for?
