Hello, We changed the engine and no eletricity on the ignition coil when kicking...so the engine can't start. We changed the ECU but that was not the problem! This is a Toyota Previa 2000/ 2AZFE. Thanks for your help.

1990 nisan n13 motor 1.6, has no spark to coil i drove car to train station, when i got back the car would not start, replaced coil, distributor, ecu box, all fuesible links, plugs & plug leads, fuel...


Your car has both a crank and cam position sensor. First start with your crankshaft position sensor. It is located by the harmonic balancer on the front of the motor.

Hello! I've been there too. I guess you have touched your coil after the engine stops. If the coil is hot, usually the cause is a very high resistance in the high tension circuit. That is between the coil and spark plugs. Probably something makes a false contact or loose conection or the gap at the plugs it too big.
If your coil is cold, perhaps your coolant temperature sensor is bad. This sensor tells the ecu or the cold start valve to squirt more fuel. When it fails your engine can't start when cold or it dies when hot depending on the failure type. Another thing which can go wrong if your coil is cold can be the cold start valve. This is an auxiliar injector located at the throttle body. When it fails, it simply doesn't inject fuel or injects all the time! (Only 80's cars have cold start valve)

93 cherokee no fire to coil what could be the problem please help


Look at your dash gauges when you turn on the ignition....is the check engine light coming on? If not, your ecu computer needs to be repaired since the ecu will not sent power to the main relays until that check engine light comes on. No power to the main relays means no power to your ignition coil or fuel pump. Repair services are available.

No spark from ignition coil to start the engine of suzuki vitara16v EFI engine. what is the cause of it


what year? what country? sounds like suzuki G16b engine. is it? or 2.0L?
The reasons are the same basically for G16 or the 2.0L
Both engines have ECU.
Both need good fuses to power ECU and coils.
Both engines need working CMP.
my guess is this is a distributor engien G16b (YOU SAND COIL NOT COILS.)
1: fuses, test the fuses relate to ECM/PCM (3 fuses)
CEL LAMP MUST BE ON KEY ON OR ECU HAS NO POWER.
2: g16B( CRANK FOR 5 seconds), with scan tool connected.
A $50 tool that is indispensable.
P0355 or P340 DTC , bingo, no spark.
or while cranking RPM is dead at 0 RPM.
if all that passes, then check the coil signals. (@ minus term)
The coil has an ignitor in the dizzy and both can go bad.
recap.
power 12v to ECU
CMP working
ECu sees CMP and sends spark to dizzy ignitor.
Ignitor , drives coil, coil makes spark ,engine runs.

No fire i have changed cap and button ignition module and i am getting power to the coil


If the check engine light does NOT come on when cranking, at the times when it won't start, and the relays are clicking and buzzing, then your ECU is in need of repair. The engine will only start after the check engine light comes on and the ecu is what controls that. ECU is likely going bad, causing the delayed start problem typical of early 90's jeeps. Reasonably priced repair or replacement services for your jeep ECU are available on ebay.

I would check the injectors for each cylinder, and check for spark in each cylinder.

If the injectors are not firing in all cylinders, it may be a computer.

If spark occurs in some but not all cylinders, it could be an ignition coil.

DISTRIBUTORLESS IGNITION SYSTEM General Information A distributorless ignition system is used on all 2.2L and 2.5L models. The system consists of a cam and crankshaft angle sensor, knock sensor, two ignition coils, an Electronic Control Unit (ECU) and assorted sensors. The system control features a quick response learning control method that compares data stored in the ECU memory to data received from the sensors. Thus, the ECU constantly provides the optimum ignition timing in relation to output, fuel consumption, exhaust gas and other variables. The ECU receives signals from the airflow sensor, water temperature sensor, crank angle sensor, cam angle sensor, knock sensor and other various indicators to judge the operating condition of the engine. It then selects the optimum ignition timing stored in the memory and immediately transmits a primary current OFF signal to the igniter to control the ignition timing. The ECU also receives signals emitted from the knock sensor. Ignition timing is controlled so that advanced ignition timing is maintained immediately before engine knock occurs. Two ignition coils are used, one for the No. 1 and No. 2 cylinders, and one for the No. 3 and No. 4 cylinders. A simultaneous ignition type is employed for each bank of cylinders. This eliminates the distributor and achieves maintenance free operation. Ignition control under normal conditions is performed by the ECU measuring engine revolutions. Using the data it receives, the ECU decides the ignition timing according to engine operation. Ignition control under starting conditions is set by the ECU at 10°BTDC. prev.gif next.gif

What causes to burn out one of the ignition coil of 03 bmw 325i


replace the busted transistor in your ECU. For Bosch 30011 or 30014 you can use BU323Z transistor for replacement. it´s 100% pin-compatible and released for transistor ignition systems.

Doesn't start


I assume that when you started the car the starter was running and the engine was cranking.
Remove the #1 boot from spark plug 1. Insert a screw driver to the booth, bring the screw driver near the engine body (about 2 mm) and let someone start the engine. If there's no spark, replace the ignition coil. If there's a spark, check the ignition timing with a strobe light.

Before changing the ignition coil, make sure that the wires connected to it are alright. Remove them from the coil and switch on the engine. Measure the DC volts from the wires. You should get a 12 volts reading between them.
