Hi there,

For a crank-no-start scenario; there are only two possible reasons: 1) no fuel; or 2) no spark.

If you pulled your plugs and tested for spark on turnover then it's not likely spark. This leaves fuel. If you have fuel pressure in the fuel bar that's good, but it may not be getting to the cylinders because of the injectors. The computer may be preventing fuel because of a sensor fault along the fuel system. For my Chevrolet same issue was on account of the throttle body position sensor. The potentiometer had cracks in it causing bad communication with the computer- computer then shut down the fuel system.

If it is an automatic try turning the ignition on and moving the shifter all the way down and place it in neutral to start it if not then put it in park and make sure it is all the way in good luck! Ed

SOURCE: 98 jetta wont start with a good battery and good starter

A common plroblem on the 2.0 engine cars is the distributer, try changing that, if that doesnt work their is a sensor in the block right behind the oil filter than can cause the no start issue, but its not as common

SOURCE: 1998 Pontiac transport van wont start:

Well you hit all the major ones, could be crank position sensor, ignition module, a bad coil pack (it should have 3), you need to check that you have spark to each plug while the engine is turning over (!!!be careful as this will hurt if you get shocked!!!), this will rule out coil packs. if you have no spark to any plug your looking at a bad ingnition module (which is what the coil packs bolt to). Hope this gets you on the right track!

You most likely have no injector pulse,this is caused by a bad cam sensor,or pick up coil,or crankshaft sensor.

My '98 S10 ignition switch will click, then work.

first check all cables for corrosion on the battery. then go under the truck and check all cables that are on the starter. if they are clean then replace the starter because the solenoid is going bad.

Wont start up...

Check for a bad ground from battery to engine. Then check the module inside of the distributor cap. It should be a black crescent shaped unit about three inches long that all the wires plug into.

My fiancie's starter just went out on her 98 chevey cavalier and I need to know how to fix it.Ive changed my starter on my ford explore and it was quite easy so Im hoping that it wont be as difficult on...

judging by labor times if its the 2.2 liter it only pays 8/10ths , can't be that bad , if its the 2.4liter , it pays 1.2 hrs , could be a little more tricky. good luck with that
