My car cranking but wont start.I have been replace fuel pump,spark plugs and crank angle sensor but no start.I need to help please.


Codes help. But you need to check what you don't have. Fuel pressure or spark at the coils/plugs. I know you replaced them, but it could be a bad wire, plug, or fuse. Could be a bad ECU.

Its a 1993 dodge colt vista se we shut off the engine & know it just turns over but wont start


Probably lost either spark or fuel to the engine. Try starting it with starting fluid into the intake. If nothing happens, check for spark on a spark plug wire- probably the ignition system. If it runs for a second or two with starting fluid, it is a fuel problem-check fuel pressure to see if the fuel pump is still working.

My 93 plymouth laser wont start


If a starter is able to crank the engine but it won't start you usually have either an electrical or fuel problem. It's also remotely possibly that it's compression.

If an engine has proper fuel, spark and compression, it will start when you crank it. So your challange is to find out which part isn't working right. Start with fuel. Spray a little starting fluid into the air intake while someone tries to start the engine. If it starts briefly when you're spraying starting fluid, you probably have a fuel delivery problem. That could be injectors, fuel pump, fuel filter, relay, fuse... who knows what until you check into it.

If it doesn't start with starting fluid, check the spark. Pull a plug wire and attach it to a spare sparkplug and set the plug on a solid metal part of the engine. Have a helper crank the engine while you watch the plug. If you have a good spark, it might just be out of timing.

In any case, you'll need to start isolating the problem. Find out which part isn't working then you'll know what to replace/repair.

Cranks but wont start


you need to check for spark at the plugs while cranking.then check for fuel entering the intake at the injectors.you don`t say if its a 4 or 6 cylinder.if its a 4 cylinder you can look into the throttle body while someone cranks the motor and you should see fuel squirting into the intake.if you have no spark then check to make sure the cap and rotor is in good condition and the rotor is turning(if not then the timing belt maybe broken and needs replacing.also check the plugs as if they are worn so bad you won`t get any spark.a common problem on these is the coil pickup in the distributor going bad.there is a 2 wire connector that comes out of the distributor with a plug,if you follow this wire back into the distributor you will see the pickup.also check and see if you can hear the fuel pump running while cranking,you may have a bad fuel pump.you may have to remove the gas cap and listen at the filler neck or listen under the car were the gas tank is.if the fuel pump is not running then you can hit the fuel tank in the middle while someone cranks the motor and it might start.if so then the fuel pump is no good another common problem.there is a fuel pump relay under the hood on the drivers side that sometimes goes bad or there is bad connections.most of this checking is good for the 6 cylinder as well except you can see the fuel squirting into the intake.it could also be a bad computer that will have to be checked out at a shop.

I have a mitsubishi colt, and it has problems starting in the mornings. It turns over, but wont start, when I eventually get it started its very lumpy, and when I push the accellerator the engine almost...


There is no simple answer, there are to many variables. If you have access to a scan tool, pulling the codes should help. Without them its back to old school hunt and peck method. At this point we need to narrow down the problem. You need to test for spark.
  1. Tag and disconnect the spark plug wires from the spark plugs.
  2. Remove the spark plugs and install the spark plug wires to each spark plug.
  3. Ground (do not hold spark plug) the spark plug; check if spark occurs while engine is being cranked.
Crank the engine for no more than 2 seconds at a time to prevent flooding the engine with gasoline.
If you have spark, You will want to make sure you have fuel injector pulse, along with fuel pressure. If you have spark ..simply spray some starting fluid in through the air filter and hold the gas pedal to the floor and crank it over while spraying. If it fires up, you know it is fuel related( fuel pump, regulator, or ECM if no injector pulse) . If you have no spark then look at ignition coil connection and trace through to the distributor( if equipped ). The crank shaft sensor has a tendency to fail on these as well. This should give you a few things to test and check to start you on your way to narrowing it down. If you have no spark then look at ignition coil connection for power and trace through to the distributor( if equipped ). If it is DIS( no distributor). It may be the Crank sensor or the ECU. The crank shaft sensor has a tendency to fail on these as well.
The ECU uses the signal sent from the Crank sensor to trigger the spark and fuel injectors. ( make certain you have checked all fuses)

Wont start


is the your car engine cranking when you try to start, first check spark plugs ignition coils, remove one ignition coil and spark plug fix the spark plug in to the ignition coil then connect ignition coil to wiring and keep spark plug body touching on ground of engine head mettle parts, ask some one to crank engine then you can see is the plug sparking or not, do the same way to all the coils and plug otherwise you have to buy a ignition spark tester, is the all the coils and spark plugs are OK then check the fuel pump, it's sitting in under rear seat, before that do one thing disconnect oxygen (O2) sensor wiring and crank engine, the thing is if your oxygen sensor completely dead fuel pump will stop working, if engine start after disconnect O2 sensor, replace new O2 sensor, otherwise need to check fuel pump relay fuse and fuel pump. is this information helped you? please vote me and give a comment.

I don't know why, but the car isn't getting fuel. If it cranks and has spark but does not fire then it is a good chance the fuel pump is no longer operating properly. Once easy way to test this is to see if you can hear the fuel pump operating. You should be able to hear it when you turn your key to the "on" position (just before starting the engine). There should be a momentary buzz from the back as the fuel pump pressurizes the line.
