Nissan Sentra 1995 sti cracking but does not want to start, battery and starter in perfect order, does have spark on plugs and fuel feeding injectors can you advise

You do not have a fuel pump, fuel pressure regulator, or other fuel-related issue.
What you have, in fact, is an issue with the fuel injectors. All 4 injectors get constant power, and the ECU provides a pulsed ground circuit (in milliseconds) to energize the injector (the ground completes the circuit, pulls the electromagnet open to let the fuel spray). If the ground circuit is constant, as in your case, you will have the injectors spraying all of the time, as you have described seeing fuel on the tops of the pistons. This can only be caused by these 2 factors: either you have a chafed injector ground wire shorting that wire to a ground on the engine, or a bad ECU.

Did you change the spark plug?? Your car (1993) has a distibutor assy, which means it has ignition wires for each plug. How are your wires??cap?? rotor?? Have you ever done ignition tune up?? If the answer is yes and you have already installed new injector and pressure regulator (althoug it still could be a injection issue/ECM or computer, because ECM is what drives the injectors. If the ECM or wiring to #1 injector has an issue, the injector will not fire off and put gas into the cylinder, resulting in a misfire.) Remove #1 injector connector and check to see if you have power/12V on one side of the connector. If you have 12V there, than check the other wire for continuity to the ECM. You will need wiring diagram to find the right wire color at the ECM. That other wire goes into the ECM to the driver which opens and closes the injector depending on your demands as far as gas pedal input. That driver may be bad, causing the injector not to shoot gasoline. Than I would be looking into a engine issue, such as burned valve, or head gasket problem (coolant getting into #1 cylinder, flooding your spark plug). Tough to diagnose over the computer and not looking at it my self. Let me know what you find.

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA

hay man. have you tried to see if your fuel pump is working or is it out of gas, Then you could checkyour timing good luck!
