My wifes Jeep cuts out completely when you plant the foot down.
We just had a service done where mechanic had trouble bleeding air from the system after genuine fuel filter change.
He found a leaky pipe and replaced with genuine one.
Now everything shuts down when you accelerate to overtake which could be disastrous
Vehicle is back at mechanics and he is at a loss as to why the computer seems to think there is no fuel and shuts everything down.
Also fuel light on dash comes on and stays on.
Any thoughts our there would be appreciated
Cheers Ray
P.S When it stops and you pull over it starts straight away without a problem

may
well be simply fuel, the computer is most probally fine but if it runs out of fuel no computer can help you...
I dont know Jeep
well but if anything was changed start looking there first, i will assume it starts fine, idles fine, and all is normal when just cruising, you go to pass something and it cuts out, you panic (bugger of a thing to happen,...) and pull over, start it up and away you go again ??????
For me i would look for a fuel restriction, to start and run normal does not require as much fuel flow, when you put your foot flat it demands full flow of fuel and it simply get to a point where it cant suck as hard as required and cuts out .....
I have had exactly the same happen to me, took weeks to find and was a blockage in the line into the injector pump, tiny little gause filter deep down in the pump, big as jelly bean, blocked with fine hairy stuff ......
May be off track but hope it helps..
Cheers
Joe

Thanks Joe
You're right, it operates perfect except when you put the foot down.
So will get mechanic to look for fuel restriction/blockage, bugger of a motor to work on, no room to get hands in anywhere

Yeah, it will almost certainly be fuel starvation as indicated by the computer.
The cause will probably be air in the system so try bleeding it at the filter, but before you do that,
check the installation of the filter itself. Did the mech use a genuine filter or has he fitted something that doesn't flow as
well? Is it fitted incorrectly and then compressed and is blocking some of the fuel flow?

Hi Joe
Yes he used genuine fuel filter as I had to get a bank loan to pay for it.. lol
We all seem to think it has air in the system somewhere.
Must be sucking it in somewhere as it has been bled correctly even if it did take some time.
Will get him to
check if filter is fitted properly
