2000 TJ 4.0
Died at highway speed
Started up again and got home
No codes from ECU
Replaced fuel & fuel pump
48 lbs of pressure at the fuel rail
On my way home yesterday my 2000 TJ died at highway speed, then came back to life just as quickly. Then died for good.
(With that I know the cam position sensor is ruled out. It has been replaced, and the ECU only uses that sensor when it starts up.)
As I was waiting for tow, I kept trying any trying to get it to start. After about 30 minutes it fired up, and died. But I gave it another crank and it fired up, and I drove home, just 3 miles.
It hasn't thrown any codes either.
I read another post in the forum that indicated it might be a fuel pump. With 150,000 miles, it needed one anyway, so I replaced the fuel pump and fuel, and it still won't start.
I turn the key and the pump buzzes. At one point, with the key on for several minutes I heard the pump buz. So I tried again. It started up, but only for a few seconds.
Any suggestion or known issues like this?
Thanks in advance,
