Truck falling on its face when in drive

I have doubts that whoever checked the FUEL pressure knew what they were doing. There should be no need to race the engine on a lift in gear.

Hahaha right,it told the guy it falls when you get in it so that’s why he was going so fast

You need to measure the fuel pressure while accelerating when the problem occurs, free wheeling on the lift proves nothing.

Ok sounds like I’m gunna have to do another fule pressure test

When I suspected a fuel pressure issue, I connected the fuel tester and taped it to the windshield so I could read the pressure while I was driving. Just have to have a long enough hose on the tester.

Have u done a compression test? Leak down test? U might be putting lipstick on a pig.

Any luck on this? I’ve got the same thing going on with my 94 and have replaced just as many parts with no results.
