Re: 97 Jeep Grand Cherokee Laredo kills while driving
At first it wasn't reading any fault codes except for when the battery was
disconnected. But day before yesterday it started reading code 43 and I
know in the Haynes it stands for "multiple cylinder mis-fires". I've had
been paying close attention to when my Jeep goes to kill while I am
driving and it seems that when I hit speeds between 30 and 40 mph that is
when it kills or tries to kill. But long as I am parked/stopped it
doesn't. It is so odd, I have never had a truck do this to me before.

Re: 97 Jeep Grand Cherokee Laredo kills while driving
Just out of curiosity, how much gas was in the tank whenever this
happened? 1/4 tank or less, maybe?
The '97 4.0L ZJs had a TSB to replace faulty fuel pumps that would
falter or momentarily stop pumping at a 1/4 tank or lower, when
accelerating or when making sharp left turns. Sometimes the engine
would just die in traffic, causing a few accidents, or the engine would
go dry for a few seconds and kick back in (just before you got
rear-ended). I've had two '97s, and both suffered the problem. Dealer
changed the pump 2x on the first one - the first tme they used another
defective pump assembly - I'm about to take in the second one for the
same repair.

I just replaced my fuel pump. I've had it do that when turning left
with a 1/4 tank. I've also had it not start right up, stall out
after starting and taking a long time to start. If you can handle it,
a new pump for a '97 TJ is $99 at Pep Boys, $220 at Papa and $420
at the $tealership.
