Need to connect a fuel pressure gauge and see if you are getting sufficient pressure to the tbi

take your distributor cap off and check the ignition module for loose wires or even a ground strap thats connected to the engine to the body , you can take the module to autozone and have it checked for free, it might have a crank position sensor thats going wacky

Check the fuel pressure, I would bet your pump is weak.

it sounds like you have fuel starvation. try cleaning out your carbourator

Well, first off would be to replace the faulty sending unit so that the oil pressure will stabilize. Second, if I'm reading this correctly that you have no oil in the oil filter at all? If not, your oil pump could be quitting or it did quit. It's recommended not to start the truck until it can be checked for oil pump operation. Have the valves been chattering badly? The only 3 things that would prevent oil from getting to the oil filter are a blocked passage, a failed oil pump or no oil in the motor at all. When the oil guage has that fluctuation is when the pump is going out or again the engine has no oil or a leak so massive that the guage can't hold a stable reading. Good luck

check for a blown fuse

I had a similar problem with my 1994 Ford F-150. The truck would start and I could drive fine for about a mile or so and then it would cut off. After about an hour it would start again and do the same thing. I discovered that the coil was bad. However, you may have a coil pack on yours. Have your coil or coil pack checked.

This sounds like an ignition timing issue. Check it with a timing light or take it to a tune-up shop.

Sounds as if the lingage has come loose. You will need to pull the cover off the inside of the lift gate.

Blown fuse, broken wire or abad brake light switch behind tbe pedal

GM fusible links are always 2 sizes smaller than the wire they are in, so I think you are looking for about size 14 wire, or you could buy new links and splice them in.

sounds like your fuel pump is bad. take your fuel pump off and then check it to see if it runs need good fuel pressure for the injectors to work right
