Going 35 mph my truck died completely. Tried to start it by popping the clutch and the wheels seemed locked up.


First, when you pop the clutch, you need to be in a high gear, such as 3rd.  This is due to the fact that in the low gears, the motor has enough compression to lock up the tires.

As far as dieing, this could be anything from a bad fuel pump, to a blown fuse.  Without actually looking at it, there are too many things that can cause this to give you an actual solution.  

Remember, though, that there are only 2 things that can kill an engine, and these are, no spark, or no fuel getting to the motor.  This being said, there are quick ways to test this.  One is to check for fuel pressure at the fuel rail, and check the fuses.

Other than this, I would suggest that your purchase a repair manual at your local auto parts store, as it will give you instructions on checking out these problems, along with pictures and diagrams to assist you.

Will discuss suspensions, lifts, lockers along with tire suggestions. Trail ratings and possible requirements needed for specific type of trails. Safety equipment and what you should carry with you. Certified off-road instructor. I am not a mechanic, and 4-Wheeling is a hobby, so if I can't answer a technical question it is due to my mechanical knowledge being related to vehicles that I have owned, or have worked on. I do not have manuals on all vehicles, and I suggest that you obtain a repair manual for mechanical problems and do some research before asking your question. Most mechanical questions can't be answered completely without looking at, or listening to the vehicle in person.


40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range. Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland. Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
