Hows it going guys, I drive a DA with a b18c motor in it and it was running fine before and then acouple of days later when i tried starting the car, nothing happened. I did certain things t check what could be the problem, first thought was the fuel wasn't going into the chamber so i checked fuel pump, fuel filter, fuel injectors, and found out that theres no vacuum pulling fuel into the injectors or chamber. I'm waiting to get some tools to check for vacuum leaks but would like to know if anyone would know or assume where the problem lies. Thanks in Advance.

 

The statement "nothing happened" is too vague to try to diagnose the problem.

Vacuum does not pull fuel into the injectors. They receive fuel undr pressure from the fuel pump.

A simple vacuum leak shouldn't prevent the engine from starting.

Is the timing belt good? (cam shaft turning?)

 

check for spark??

 

Timing belt looks good, but its like it doesnt seem like its getting any gas. By buddie checked a hose thats suppose to have a vacuum doesnt have it.

 

That vacuum line going to the fuel pressure regulator doesnt have vacuum unless the car is running. The fuel is pushed from the pump to the engine. Check for spark, could be the coil.

 

Ok, well I'm going to go check the sparks and all the ignition.

 

Well Sparks were weak and replaced them and became strong. But still not starting. . . . No matter how many times i cranked it fueld doesnt get into the combustion chambers. The amount of times i cranked it would have flooded the engine but to my surprise nothing.
My cousin said there is no vacuum to the fuel pressure regulator

 

check all fuses, then see if your getting power to the fuel pump which i think is located under the rear seat.

There will be no significant vacuum to the fuel presure regulator unless the engine is running to generate it, so forget about that.

You seem to be saying you are not getting any fuel. Does the pump hum for about 2 seconds when the key is first turned to the 'run' position?

 

Fuel Pump hums, so its working and the fuses all have current flowing through them. . . any other suggestions?

 

So i had time to look at the car again, I was wondering if the fuel pressure regulator should be able to flow openly. I tried blowing into it, and making a vacuum and nothing. no air passed through or comes out of the regulator. Could this be the problem. . . .

 

do you have gas in the tank?

 

yea i do

 

You seem to be fixated on the fuel pressure regulator. Forget it, it's not the problem. Is fuel getting to the rail? (it will regardless of the condition of the regulator)
