When you turn the key to the start position does the starter spin the engine ? The engine cranks no start ! Or nothing happens when you the key to start position ? no crank no start ? Is the anti-theft light lit on the instrument cluster (SECURITY) ? If the starter spins the engine does spin slow or normally ? Is there spark , fuel pressure ? Testing these thing's would be the place to start if the engine spins ! Videos on youtube showing how !

Thats exactly what it is , have the same problem with my ASTRO VAN , replace twice in 2 years average. hope this helps AJ

You need to check the fuel pressure to the TBI. I just fought one which was doing the same thing. I pulled the fuel tank to replace the fuel pump. It turned out to be the short hose from the fuel pump to the steel line coming out of the tank. It had a split in it so I wasn't getting enough fuel pressure. Some places show two pumps available. One you can pull the unit and replace just the pump. The other the pump and sender are all one unit. Hopefully you have the first one. The second is around $300.
The easiest way to get to the top of the tank is to pull the front 6 bolts mounting the bed and loosen the back two. Take the three screws from the filler neck and unhook the rear axle vent tube. You can then take an engine hoist and lift the front of the box. You can get right to the pump and gauge assemble in the top of the tank. Most times, this works easier than emptying the fuel tank and removing it.

You need to get the computer scanned. This can be done at Auto Zone or similar parts stores free of charge. More than likely you will just need new spark plugs and/or plug wires but I cannot be certain without the engine code.
Hope this helps, remember to rate this answer.

you should check alternator for correct voltage!! on my car the alternator cable came loose and the dash lights kept flashing and then the car just quit. if alternator fails you will not get enough juice to run sensors or pcm...

MY turn! OK, Fuel system, supply and demand. Once upon a time, someone thought of a way to have a vehicle imitate a humanNow a car exchanges tons of information and the result is the same. the whole mass gets confused about the objective and that is to get moving.
A quick run down on efficiency. There are numerous sensors in a motor vehivcle but we will just touch may the five or six that count. Furst we have thefuel pimp. Supply only on demand. If the fuel syatem maintains a residual pressure in the fuel system it will no have reason to prime. The vapor recovery system and gas cap only recycles fumes that condense and gives the left overs to the engine.Hence hard starting because it screws up the air fuel ratio by bypassing thesystem fuel controls. Which are: The coolant temp and the intake air temp sensors. These two team up to function as the choke/cold start like in the good old cars,They enrich the fuel on startup.Once he engine and air temps are optimal, they allow the fuel mixture to be controlled bt the Mass air flow sensor. This sensoris mounted inside a rigid section of the intake ducting. Once it takes over, it starts reading the density, volume and velocty of yhe intake airand through the ranges meters the proper amount iof fuel in relation to the air being induced. The throttle positioning vavle simply lets the fuel get to the injectors according to how much ias requred to get the desired results.smoothly.. The air filter condition is critical because it impedes air flow and if in poor shape filtration wise, it allows dirt to accumulate on the MAF sensor sensing componants.In the event the MAF cannot read properly it affects the fuel supply directly by ling to the computer. A dirty sensor reads low air volume and velocity and cuts back on the fuel, leanning it out and the vehicle stalls, runs rough, hard starts, and surges. AND, we have arrived back at Dennis.and his dilemna. Vehicle unreliable.. As you can see, the other sensors are in the shadows right now. In the shadow of the MAF sensor. The MAF SENSOR CAN BE CLEANED using only CRC electrical spray cleaner. Thoroughly wasjing(rinsing) the sensor avoiding touching, rubbing, or brushing. The spray cleaner dries rapidly and compressed air must not be used.. Once cleaned, everyone should be "on the road again" I hope this info helps you dennis.. Good Luck-Ned
