The injector is electronically pulsed with voltage at the correct time for fuel to enter the cylinder. You can ohm the injector with a meter to check. If injector ohms good, then ECM is not working correctly, putting out the voltage pulse to fire the injector. Not sure on the value for your injector...

Change the fuel pump and still won't start on a 2002 chevy avalanche


Check for spark to the spark plugs, while cranking the engine. If no spark, you could have a bad ignition module, or a bad crankshaft position sensor. The crank sensor sends a signal to the computer, to start the fuel pump and signals the ignition module to start firing the spark plugs. It also drives the tachometer through the computer (PCM) Powertrain control module. The ignition module can be removed and taken to a parts store to have it tested. The crank position sensor is not as easy to test. Easier to just replace it. Good Luck. But wait, I have seen people replace the fuel pump, checked the fuel pump harness for power, and all was good. However, if the fuel pump does not have a GROUND, it will still not operate. Might want to check that. Have fun.

John deere 445 96 w 22 horse kawasaki fuel injected starts fine runs but rough with raw exhaust gas new olugs new fuel &filter new oil


When it runs rough is it blowing dark smoke? This is a sign of running rich like a choke will do and can cause stalling especially when the motor is warmed up. If it is not blowing dark smoke it sounds like maybe your injectors are not working properly and it is not getting enough fuel through them under load. either way as an injected machine it sounds like injectors may be the culprit since youve taken care of some other issues. You might try running a heavy dose of an injector cleaner through it (I've had good results with lucas brand) and see if that helps. Otherwise, you might try to manually clean the injectors.

No negative to my injectors


Fuel injector circuits typically have a power source tied to the ignition switch & the ground is controlled by transistors within the powertrain control module. Ground is only provided during engine operation & cranking. The easiest way to test this is a Noid light or test light. If there is no ground pulse while cranking you should inspect the ignition system. Primarily the Crankshaft Position Sensor. The crankshaft sensor tells the powertrain control module where the engine is in rotation so it can send a signal to the fuel injector at the proper time.

Things to check:
-Power to injector
-Ground pulse during cranking
-Crankshaft Position Sensor

JD 445 no fire to the plugs and no fuel from the injector I tried another used A-1 coil checked all relays according to Tech manual all fuses good no broken wires


Check all safety interlocks. Any one will prevent the engine from starting.
1. Seat switch.
2. Brake interlock.
3. Blade interlock.
I don't know of any others. If any of these switches is OPEN the start circuit will not work.

Fuel is not coming out of injector got power to one side of plug got fuel pressure


SOUNDS LIKE U HAVE NO INJECTOR PULSE WHICH IS THE GROUND SENT FROM THE ECM WHICH IS SIGNALED THROUGH YOUR IGNITION MODULE. U NEED TO GET A NOID LAMP. IT CHECKS FOR PULSEWIDTH.(LIGHTS UP IF U HAVE A HOT AND GROUND WHILE U ARE CRANKING HE ENGINE. IF IT LIGHTS WHILE U ARE CRANKING AND NO FUEL THEN THE INJECTOR IS DEFECTIVE. IF IT DOESNT THEN THE ECM IS BAD OR IGNITION MODULE IS

John Deere 445 Garden Tractor, starts immediately,


could be bad gas, but it sounds like a choke problem. did it sit over the winter with less than a half tank of gas in it. try putting some rubbing alcohol in the fuel or draining the tank and disconnecting the gas line so you can drain the gas out of the carb. also check the gap of the spark plug and make sure that is correct. when was the last time there was fresh oil put in. also check the air filter, it could be full of dirt.

Car starts until i let key off from crank position,ldles briefly, then dies like it runs out of fuel.bled off fuel line and there is plenty of fuel and pressure,


It idles briefly since it gets gas from your cold start valve. This means your cold start valve is good.
It dies since after that cold start valve will close as it designed that way so fuel from injectors will take over. But apparently fuel is not coming from injectors. And injectors is controlled by injector module. Injectors are normally closed until injector module tells them to open.
Check out your fuel injectors and Injector Module.
You can buy NOID from any auto part store to test your injectors. If there is no light on then there is a problem with Injector Module. If there is light on the injectors then bad injectors.
Here how NOID looks
