Hey all!
My Ra isn't starting. So far I've checked, timing belt is good. Compression is 210 psi across the board. If replaced the cam shaft position sensor and the crank shaft position sensor. All 4 cylinders have spark.
I believe I have a fuel issue. It's a new fuel pump that's in it. The injectors are getting power and have pulse as well tested via test light. I pulled the fuel line from the rail and put it in a jug, cranked the engine over and it fills the jug no problem. So fuel pump is pumping.
Reason I believe it's a fuel issue is if I spray aerosol sure start fluid in the intake it starts and runs for a few seconds until the start fluid is gone.
I pulled the injectors and bench tested them. They spray fine and I cleaned them while they were out.
What am I missing here? Like I said it starts and runs off the sure starter fluid. Am I not getting enough fuel pressure possibly? I don't see a port to put a gauge to test the pressure. What else could be happening here?
