1998 Jeep Grand Cherokee

Hello, I have a 1998 Jeep Grand Cherokee with a Inline 6, 4.0L, and it is
having some starting issues. It will take it forever to start, it will
crank over about 10-15 times and then finally start, Do you have any
sugestions? I have replaced: Spark Plugs, had all liquids changed, and
etc. Could you help? Thanks

Try turning the key on, waiting for the pump to stop
buzzing, turn the key off, turn the key back on, then
turn the key to start. If this solves the issue
then you have a problem with pressure bleed down.

Also pull the codes.

That did the trick by turning the key of for 5 seconds... So how can I fix
the problem?

I hope yours is like an '02 and they moved the regulator/filter
outside the tank: http://www.billhughes.com/temp/WJfuelRegulator.pdf

For now, the key trick.

Hopefully you have the system Bill pointed out. If so your in luck
because on the 93-95 it was either the fuel rail pressure regulator
(easy but not cheap) or the fuel pump check valve (not easy and not cheap)

That's where Ford and GM put them. Makes for a full pressure ninety
pounds test easy.

Do you think using a replaceable filter before the regulator is feasible?

It would have a working pressure of about 50 PSI

I don't see why not.

Now that you've pried your hands off the wallet.

Look for an aftermarket filter for fuel injection that uses commonly
available fittings. They don't have to be reusable but they should
be rated for at least 70psi, most are rated up to 100 burst. I routinely
put 72psi on the stock ZJ filter. But it uses those hard-to-find O-ring
clippy things.

Hi Bill,
Seeing yours is external I'd just go ahead a replace it and the
regulator, probably on a fifty thousand mile interval, or a trip to
Mexico. Nothing's said about it at in your lube schedule:

I was thinking perhaps one of those oil filter sized ones like Ford used in
my T-bird and daughter's Cougar. I could cut and flare the steel the steel
tube and use high pressure hose and a couple stainless steel clamps
