Question about 1998 Jeep Grand Cherokee
New plugs new cat and brakes new ignition wire, getting strong battery starter and ignition however engine will not turn over on first crank will fire on subsequent cranks thought fuel filter? or fuel pump?
Could be either...you can replace filter/regulator on top of tank sending unit and re-check. You can also try instesd of cranking on first try, just turn the key to run and leave it like that for a minute, then try it. If it starts, likely the fuel pump is draining back when off. If neither help, check to see if on initial start, you get a small puff of black smoke from tailpipe...if so, likely you have a leaking injector. (line pressure loss at engine end of the fuel system through injector) This is the "backyard diagnosis" Otherwise tests can be made using pressure gauge installed on fuel rail.
