Question about 1999 Daewoo Leganza

1 Answer

My Daewoo won't start. I have checked all fuses and relays, checked the fuel supply. I pulled the ignition lead off No. 1 spark plug and shorted to ground but I don't have a spark.

My 2001 ultra shut down I cranks but no spark. and the check engine light wont come on when I turn ignition on


Hi Anonymous, when checking for spark the CKP needs to measure the compression bump in order to send the correct signal to the ICM/ECM so always check for spark with either a third plug grounded or lift the end of the plug boot 1/2 " off one of spark plugs that are in the head. and the usual suspects are:
1. Fuel tank empty
2. Fuel supply valve turned off.
3. Fouled spark plugs.
4. Engine flooded with gasoline as a result of over use of enrichner.
5. Fuel valve or filter clogged.
6. Vacuum hose to automatic fuel supply valve disconnected, leaking, or pinched.
7. Discharged battery, loose or broken battery connections especially the negative cable at "BOTH" ends
8. Loose wire connection at coil, battery or plug between ignition sensor and module.
9. Spark plug cables in bad condition and shorting, spark plug cable connections loose,
or cables connected to wrong cylinders.
10. Ignition timing incorrect due to faulty ignition coil, ignition module, or sensors " Manifold Absolute Pressure" "Camshaft Position Sensor" "Crank Position Sensor" "Brake Apply Sensor
11. Engine lubricant to heavy ( winter operation )
12. Sticking or damaged valves or push rod wrong length.
13. Primary cam sproket spline sheared or missing spacer.
14. Security alarm system not disarming. 1992 and later Touring Models, fuel pump fuses and relays will be behind the right side panel, starter and ignition relays will be under the seat behind the battery, everything else will be behind the left side panel to access fuses pull back on the front two locking tabs and slide the cover up.

Engines with Starting Problems


All engine regardless of manufacturer need three things to start and run. Air, Fuel and Spark, lets look at each one.

Air- this refers to air intake on four stroke engines this intake is created by the piston pulling in air with the intake valve open. You must have a combustion chamber that is sealed, meaning that there are no compression leaks from the head gasket, or from the valves. The valve timing must also be correct, meaning that the intake valve is open while the piston is going down on the intake stroke. Associated parts include the air filter, air intake manifold, intake valves, pistons and intake hoses.

Fuel- this refers to fuel supply, with out fuel an engine can not run, the fuel supply has to be correct for start and run conditions. Associated parts for fuel are fuel pumps, fuel pump relays, fuel pump fuses, fuel lines, fuel injectors, fuel hoses and carburetors.

Spark- this refers to the ignition source provided to ignite the fuel mixture. Spark is generated from an ignition coil and released in several ways. Associated parts to ignition are the ignition switch, coil, ignition module, crankshaft position sensors, camshaft position sensors, spark plug wires, spark plugs, distributors, and ignition points.

If you have a vehicle in which the engine does not run one of these three things are missing, otherwise it would work, so remember to always check the basics first it will lead you to your problem faster and cheaper.

Fuel pump not turning on


wright you have changed the supply fuel system have you checked for a fuel filter or is the fuel getting to the engine if the filter is clean and fuel is getting through then ther is no fuel issue

re spark ie plugs / points / distributor or cap if not electro / leads / coils

I have 1986 Alfa Spider that won't start. Car has been sitting for a year. I replaced battery, fuel tank, fuel sender unit, both fuel pumps. I seems that the in tank pumps is not getting any po


Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.

Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.

Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.

Not getting fire over the #1 spark plug coil. What needs to be changed/what is the cause of the problem? The engine stopped running while in motion. Battery light came on first then all the other warning...


  1. Check fuel level in fuel tank, add fuel if empty.
  2. Check battery condition and state of charge. If voltage and load test below specification, charge or replace battery.
  3. Check battery terminal and cable condition and tightness. Clean terminals and replace damaged, worn or corroded cables.
  4. Check fuel delivery system. If fuel is not reaching the fuel injectors, check for a loose electrical connector or defective fuse, relay or fuel pump and replace as necessary.
  5. Engine may have excessive wear or mechanical damage such as low cylinder cranking pressure, a broken camshaft drive system, insufficient valve clearance or bent valves.
  6. Check for fuel contamination such as water in the fuel. During winter months, the water may freeze and cause a fuel restriction. Adding a fuel additive may help, however the fuel system may require draining and purging with fresh fuel.
  7. Check for ignition system failure. Check for loose or shorted wires or damaged ignition system components. Check the spark plugs for excessive wear or incorrect electrode gap. If the problem is worse in wet weather, check for shorts between the spark plugs and the ignition coils.
  8. Check the engine management system for a failed sensor or control module.

Washed engine now car starts but slowly loses power then cuts out daewoo nubira 2l year 2000 swagon


The ignition leads are most probably wet. the leads that go down towards and over the spark plugs. Simply pull them off blow the spark plugs and leads dry with a hairdryer or preferably compressed air.

that should sort it.

Hello Sir:

There are 2 Problems that can prevent your car from starting:

#1) Make Sure your getting Fuel

#2) And Check to see if you are getting Spark to your Spark Plugs,By pulling off 1-Spark Plug wire and take plug out also, Put spark plug back in the Wire. Have someone crank the engine over,and see if theres Spark at the Spark Plug.

#3) If your car is'nt even cranking over,then the problem is in either your Ignition switch,starter relay,starter,or it can be as simple as a relay or Fuse, check in your fuse box inside,to make sure ALL fuses are good.

#4) Then under your hood you should see a plastic Cover Fuse and Relay Block as well, Check these also,Mainly if its labeled Crank,or starter. Also check your Starter relay. they are a Larger componet in the box under your hood.

#5) to check this relay you'll need a OHM meter to check for resistance. also check the EMC Fuses or Relays.

#6) if no fuel check fuel pump fuse and replace fuel filter 1st.

#7) If no Spark make check your Coils.I'm sure if you follow these tests you'll locate your problem.

Will not start


you need 3 things for engine to run
air
fuel
heat(spark)
usually its fuel or spark that is the missing link
check for spark at h.t. lead by removing one and using screw driver or spark plug or spark tester in lead held away from engine or earth point about 2-5mm and crank engine while watching for spark
check for fuel being supplied at injector rail by removing quick disconnect fitting hose to injector rail carefully with rag under try to remove slowly as soon as fuel spurts out when nearly fully off, is good it means fuel is being supplied this is under pressure if it just dribbles out no fuel being supplied this is if you havent got the right tools for the job
then depending on out come depends where to look next

Misfiring


A typical tune up includes spark plugs, air filter, fuel filter, spark plug wires, distributor cap and ignition rotor. You must determine which parts are needed before you start.
I would suggest to first check spark plugs and spark plug wires.
