first check your battery voltage and if good usually the fuel injection selenoid is suspect(hard starting ,surge, hesitation and stalling)
I'm no expert, but my friend had a similar situation in a carburated Toyota due to a clogged fuel filter. Fuel filters need to be changed every 30,000 miles or so. It's a cheap and easy fix - try that first.
== == 1) add fuel to the tank 2) fill the filter 3) crank it for 15 seconds, wait 15 seconds 4) repeat step #3 5) repeat step #3
If the engine cranks & cranks & cranks before it starts even though it's warmed up already.
Have the intake air temp. sensor checked .Two wired plug on top of intake manifold. Check fuel pump pressure.
Check for codes(possible cam sensor), check fuel pressure bleed down(possible fuel pump).
I would add fuel to the tank, and then use the fuel pump relay to prime the system. Good luck. add fuel to your fuel filter and put it back on and should start. On older diesel engines dont worry about the fuel pump relay. Add clean fresh fuel to the filter and hold the pedal to the floor while cranking and it should start.(release pedal when it starts)
A diesel engine uses the heat of compressing air to ignite the fuel instead of a spark plug like a gas engine. When it is cold it takes a bit to get enough heat to get it to fire. Ford diesels use a glow plug to heat the air when cold starting, but on a Cummins they don't use them. A simple block heater should make it easier to start when it is cold.
if its cranking but not starting most likely fuel pump
What year? What is it doing? A 12 valve has a fuel shut off solenoid that commonly malfunctions, the engine cranks but never starts.
could be disdributor
it is easier to pedal with longer cranks because you have more leverage but it is not necessarily better to have really long cranks.
Replace the engine coolant temp sensor.
check your battery voltage it needs 24 volts for the glow plugs to fully cycle up.
A 2002 Jeep Grand Cherokee engine that cranks but is not starting and has no dash gauges is experiencing an electrical system failure. This can be a result of a faulty ignition switch or damaged wiring.
if it wont crank the the starter is probally out but if it cranks and the motor doesnt turn either the belt is to loose or the engine is locked up
could be one of two problems, when starting a diesel or any injected motor you never touch the gas pedal or you might flood the engine, the glow plugs may be weak and added fuel just renders them useless, otherwise you might have a bad fuel filter or pump.
do you mean it cranks, but will not start?
There are two main types of no-starting conditions. Cranks but won't start, and no cranks no start. For a no crank no start condition it is best to suspect a problem with the starter circuit. For a cranks but won't start you have to remember that an engine requires the things to run gas, air, and spark. So what type of condition do you have?
i would say you have an injector problem. usually a cloged one can cause that.
No of cranks used in 6 cylinder engine
Do you have spark? If you do, check your cam/crank timing marks to ensure the spark is when the piston is TDC (top dead center).
Sounds like your battery may be very low; if it turns over slowly when it eventually starts turning, definitely try jump starting or charging the battery and trying again.
This is a bad question. fix it. check fuses . there are sevearal fuses that will stop it from starting
