Hard bucking when accelerating, cutouts at high RPM (parked on side of interstate)

Duredel said:
I was replacing a fuel pump on a Chrysler van once and forgot to relieve the fuel pressure before disconnecting the line. The connector above the tank is on a small jog in the line, so the disconnected line to the engine points directly downwards. I was right underneath it when I disconnected it and got the full column of high-pressure fuel blasted into my face. It went into my eyes, up my nose, and into my mouth. Of course I flinched and bashed my head on the bottom of the van. I managed to crawl out of under the van but I couldn't breathe, I couldn't see, and I was disoriented due to bashing my head. It took what felt like an eternity to be able to get a breath in, and about a minute before I could see again. There was an intense burning sensation in my nose and throat for a few hours afterwards, and I couldn't breathe or see normally until the next morning.

Don't be dumb like me, relieve fuel pressure before you do ANYTHING with a fuel line.

Amen- same story here-

Man I freaked .

You know I had a family member die years back- cleaning a car engine with gas - guy was welding - (I know, terrible )

He freaked, rubs into the bathroom, door locks , And he is screaming and burning to death and the guys cannot get in there to help him.

This was years back when things were not so safe.

I’ll get a little dramatic on here when somebody starts talking about pulling a fuel tank full of gas - But I will always encourage people to avoid anything that could lead to something like that.
 
Hi all, so I have the exact same issue with my 2000 TJ manual. It sputters and stutters and seams like all power stops for brief seconds at a time when accelerating… it starts and idles fine.
I’m at a complete loss as to where to go next!!

I have done the following:
New Spark plugs
New Coil Pack
New Igniter Plug blanket thingy
New Throttle Position Sensor
New Idle Air Control Valve
New Mass Air Flow Sensor
New Intake Air Temp Sensor
New Both O2 sensors
New Complete Exhaust
New Throttle Body
New Fuel Pump Assembly
New Catch Can
New Battery
New Air Filter

I have no codes and no CEL!! And almost no money left…

HELP!!!

Check the fuel pressure, sounds like a tired fuel pump.

Edit: Missed that you had replaced the pump, but it still sounds like a fuel issue.

Well, it could be one of the coils in the rail. You would lose 2 cylinders if one has a weak spark.

Sorry, replaced that… that was the first thing I went for!! The only thing I haven’t replaced is the PCM!
 
Are you sure there are no CELs? Is your CEL light possibly burned out? Did you check with a OBD reader?

Could you possibly be going into limp mode (RPM capped at 2500 RPM)? If so, there should definitely be a CEL.

100% mate!! Definitely no CEL 100% no codes!! CEL light comes on when turning the car on as per normal. Engine revs fine, idles fine only happens when accelerating and randomly!
 
I would be examining wire harness and grounds looking for potential shorts and bad ground connections.

One more caution on relieving fuel pressure. I was replacing a fuel filter, years past, under the car with a drop light with an incandescent bulb in it. The gas sprayed the drop light breaking the bulb in the process, I don't know why the fuel didn't ignite but it should have.
