Hi Franz, 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.
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.

Check first the state of the cables to be sure. You may also just need the terminals to be cleaned. If you have checked the plug itself the problem may just be with the cabling or the coil. Check for blown fuses and relays to be sure. Check also the battery. It may be a weak battery. Try to jump start the bike using jumper cables connected to another bike to see if you can get it started, if it starts it could be a battery getting weak. Otherwise it may be the coil that needs checking.

Check also the kill switch. You may also need it cleaned. Otherwise check the electrical components mentioned above.

My 97 bmw28is wont start everyting was working fine.batterry is full ibut cae r wont start


wont crank?
or cranks robustly (the crankshaft spins fast) but wont start.
all cars that dont start one, all ran when new. etc.
what counts is the now. only.
you need to do the tests. all covered in the FSM or at alldata.com
i cant help you because you . cuz did not say crank or start? so......

1: test all fuses. (not just gandering, use a meter)
2: check battery voltage 12.6vdc rested.
3: if not cranking, wiggle the shilter (a/t) or clutch if m/T
if a/t? try cranking in Neutral. cranks now? bingo.
4: cranks ok, and fast so check spark/

ill end there, due to vast number of tests and no clear stated
symptoms.
ever give it a full tuneup (60,000 mile service schedule?) or this DECADE. if not why ask the spark plug question.

My 96 volvo 850 gtl2.4L ENGINE CRANK OVER BUT WONT START I REPLACED THE INGNITION COIL \ POWER STAGE WITH NO RESULTS.PLEASE HELP


Reasons for engine turning over and not firing are simple. Spark or fuel. If you've changed the coil packs then chances are it's a fuel issue. Get in cab and turn ignition to second position whilst listening to back seat. You should hear the faint noise of the fuel pump working. If you can't, I suggest you firstly check your manual to find the fuse/relay for the fuel pump and check that. If they are fine, you need to replace fuel pump.

If you can hear it working and it still won't start, remove the fuel line going to injector rail and point into a jar whilst someone turns engine over. You should have fuel coming out. If this is fine, go back to ignition, remove a spark plug and turn engine over checking for a spark.

My bet is your fuel pump has packed-up. Good luck diagnosing.

1989 cutlas cera wont start its giving me code 12


Code 12 is a "good" code-it means system normal.
Since no codes are stored, check for spark and check for gas-is the fuel pump coming on? You should hear the pump buzz for a couple of seconds when you turn the key to on-it should start and pressurize the lines, then shut off until the engine is cranked-when cranking, pump should be running again. If you don't hear the pump, check if the fuel pump wire at the gas tank connector has power to it when the engine is cranking. If it does and the pump is not working, the pump will need replacing.
If no power, check the fuel pump fuse and relay, under the hood.
If the fuel pump is working, it may be ignition related-check for spark. You need to see a blue snapping spark to know the ignition system is good. If no spark, suspect the ignition control module or the crank position sensor -or the pickup coil, if no crank sensor. The pickup coil will be in the distributor-if you have one. If no distributor, crank position sensor is behind the crankshaft harmonic balancer.
If fuel pump and spark are good, you will need to diagnose the injector circuit.
Post back with what you find.

1997 thunderbird cranks and fuel pump comes on but wont start


Most likely the fuel filter is clogged. They cost around 10-15 dollars. Usually mounted somewhere along the frame rail under the vehicle. Just follow the fuel line and it will lead you to it. Also you will need a special tool to release the interior clips. The plastic tool works fine and is about 15 dollars. You can find everything at Autozone or a similar parts store. Hope this helps you.

Running fine. Died and wont start. Cranks fine


can you hear the fuel pump kick on when you turn the key on but without crancking the engine? Generally the fuel pump will prime for about two to three seconds when you first turn the key on. if you don't hear it that's probably the culprit. If you do hear it it may be a bad pump. also should check to see if you have spark. You can do this by removing a plug wire and using another spark plug. Ground the plug to somthing metal and have someone crank the engine (making sure you are not touching the plug or metal) You should see a spark while cranking. Good luck

99 yukon 180,000 mi. doesn't start. cranks forever, but won't start. Should I be able to hear the fuel pump when I turn on the key?


yes you should be able to hear the fuel pump run for about 5 seconds once the key is turned to the on pos. check to make sure you have spark. if you do try having someone spray air intake or carb cleaner into intake manifold while you crank. If the truck starts right up for a second (or stays running as you keep spraying) Id say you have a bad fuel pump and id change the sending unit also. (First check the fuel pump fuse and fuel pump relay) GMC and Chevy are nororiously known for having bad fuel pump/sending unit problems. I have prob changed over 60 myself.
