Hard starting 1998 explorer

[Red wood]

Need Info on a 1998 explorer 4.0 SOC Engine code E
Having problem hard starting. some times it starts fine and other times it cranks over but won't start. I have installed a new fuel pump but still have the same problem. This is an intermitt problem so it is hard to chase.
auto has 128,000 miles on it. Could a mass air flow sensor be the problem the thing runs fine with no driving issues after it starts

MAF sensor should just throw a code and maybe a high idle shouldnt cause starting problems. i dont remember if the sec gen's had distributors or coil packs but if it has a distributor check the contacts for corrosion

hard starting

Hey redwood .
I have a 94 ex limited with a 4.0 ohv . I am having this same problem .
Had the starter checked ,was ok . Changed both battery cables
(they needed it , they were shot . Was ok for a while . now it acts like
Its either not getting fuel or spark .
When I am able to get it started , It runs perfect .
Iam going to change the fuel pressure regulater and ignition coil to
see if this changes any thing . I was told the fuel regulator can cause hard starting
The end of this month I am going to pull the top end off my ex and redo it.
Its a ***** to get my ex started But like I said , Once my ex starts , you cant stop it . Let you Know what I find out this week end .
