You got spark or injector pulse? Battery Failed? Got any OBD Codes in the system ?

It could be the fuel pressure regulator, but that can be determined by testing the actual fuel pressure in the fuel feeder rail. But first, have you changed the fuel filter? The fuel filter usually is clogged with debris whenever a fuel pump fails, so be sure to change that first.

under the hood on the emission decal

check the switch and connections under truck as well as gear oil level if good than have truck scanned for the trouble code most auto stores do this service for free such as auto zone / advanced auto check ur local areathe code will pin point ur problem

There is an module on the passenger side near the back. It has four plugs going to it. Replace it. Other wise. rewire the plug itself.

Check shock absorbers (leaking oil) or anti roll bar bushes

needs valve job done on it

Have you replaced the fuel filter?

Was even one of those items that were replaced tested & failed a test ? Do not tell me---- IF-- a repair shop throw parts at it If that is what your doing at home--- STOP ---& seek professional help,until you learn how to diagnose a vehicle

Is the Battery any good-start there (12.6 V min) Obviously all those codes are not separate or multiple problems Check for spark,fuel pressure at the motor

For a temporary fix so the car can drive, remove the fuse for the four wheel drive. it won't actuate the four wheel. The car is always in 2wheel drive. the fuse is located under the hood, the very right side of the of the fuse box, the third fuse up from the bottom. This can be checked in the owners manual. When I need four wheel dr I place the fuse back in. I haven't fixed the problem yet but can drive it 2wheel on the road. think it is the control module for the four wheel dr located under the dash board behind the glove box. Dealer part for $450, I would rather install and remove a 10cent fuse

The engine has an automatic shut down if it reaches a certain temperature to protect the engine. Possibly it could need a new thermostat for less than $20. It is possible the thermostat is stuck in the closed position not allowing fluid to circulate throughout the engine. Try it and see. Cheaper than a mechanic to replace it for you.

you could have a problem with the ignition module that is temperature sensitive. I have run into this a couple of times. the module reaches a certain temperature for a while and it affects the electronics in the module and shuts down. the only fix is replace the module in the distributor.

Juan, you need to look for timing mark on crank shaft pully just below water pump,you will see a deep cut mark, turn over motor BY HAND disconnect battery,for safety , now remove # 1plug when you rotate motor you should feel compression , as piston comes up ,if you don't feel compression rotate motor 180 deg,as timing indecater alines with crankshaft timing mark, that should be (TDC) top dead center ,now set plug wires in firing order.make sure when starting that you have spark, if it wont start try resetting timing again, you may be 180 deg out . I hope this helped if it did let me know. Woody

Hi Kelea, I'm glad to help! Kelea, the A/C hoses and lines can be traced back from the A/C Compressor, to the Evaporator at the firewall and also to the Condenser in front of the Radiator. If you can't find the leak and your in the St Louis Mo area give me a call Al 314-374-5218 and I'll be glad to take a look at it and help you out. Hope this helps and have an awesome day Kelea.

Looks like you've covered the basics, make sure the firing order is correct with your spark plug wire replacement. Hope this diagram helps.

The most common repair is to replace the ignition lock cylinder due to broken wires inside the steering column. Most common problems related to the Passlock family involve the Passlock sensor. The sensor is part of the ignition lock cylinder on Passlock I and Passlock II systems. ( Where the key goes ), Good-Day!

can you describe the situation in more detail?

Have you checked 4 wheel drive actuator. it located under the battery. The actuator uses suction to open and close. if the rubber housing has and oil residue on it, the oil will eat the rubber causing a hole, where there will no longer be any suction.
