    Are the plugs wet? Is there spark? "will not crank" meaning the starter does not turn the engine?

Do your switch turn over? You have to have the cover on top of the motor on before it will start!

Think the oil pressure switch keeps the fuel pump running once started. Suggest replacing Oil pressure switch. And no it won't effect oil pressure reading when it goes bad. The switch is a safety device. When you roll it over and the oil pressure drops the switch cuts off the fuel pump. Neat huh? Need some good feedback Thanks!

1992 chevy lumina euro 3.1 while driving the engine acts like it is going to die then it regains power and then repeats the sluggish, lack of fuel .


check fuel pressure most likely bad fuel pump. also check your oil sending unit or gauge. chevys run the fuel relay to the oil pressure switch in case the oil is so low the car wont start. sometimes the relay in between this circuit goes bad as well. if all is well check or replace the ignition module (located directly under coils) or distributor integrated if it has a distributor

My 1995 Chevy Caprice Classic wont start what could it be


It could be many things. Check your fuses first. Make sure your fuel pump is kicking on. You should here a buzzing sound when you turn the key. You can also spray gas in the carborator and then start the car. If it starts and dies instantly, it is a fuel problem. If it changes nothing, try viewing your spark/coil wires and look for damage. Check the distributor cap and make sure the metals studs are all good. It could be a cam sensor as well. I know that is a lot of parts, but it could be any of them. If you can get a code from the computer, that is your best bet. It would give you an idea of where to look. This is if the car cranks. If it doesn't rotate, it could be your battery, a bad connection, or a starter. Write me back if you have a question. I am here to help you.

The 1992 Caprice I'm working on has no Spark to the Coil I've changed the coil and the electronic spark control module. What else besides the Fuel pump or something else could cause the problem of no start...


You say no spark to the coil. does that mean that you have checked the power to the coil & getting none or are you getting no spark from the coil to the distributer cap? If you have no spark that is most likely the problem of not starting but you can always just check your fuel pressure to see.

No power tp the fuel pump, injectors not pulsing, no fuel.


Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.

Hello thank you for using FixYa.com for your answer my name is David.
You say it wont start in the normal way by just turning it on but if you pour gas in the throttle body
it will start sounds like you have a weak fuel pump most likely but there are a few other things that could cause it also .
