OK just finished a SC swap into a 98 Mustang this weekend and the car won't start now. We got spark, and got fuel, and I removed and reinstalled the cam sensor in exactly the same position, ( had to change over to a SC timing cover) the crank did not move while it was out, I verified it by the timing marks, I know it didn't turn over at all. We also tried putting the stock tune back in the car to see if it was the tune and the same thing happens. It really sounds like a timing issue. So I spun the cam sensor 180 degrees, 90 degrees, and even just afew degrees and every time the exact same thing, it doesn't get any closer to starting when in different positions.
When I press on the schraeder valve fuel comes out but it doesn't spray out, it pours out a good amount then stops, but no spray, when you hold down the schrader valve while priming the motor it sprays out a lot, so I am thinking maybe the injecotrs are sticking open and leaking the pressure out, but the car doesn't even try to fire, so I don't know if all 6 injectors could be leaking, at least one should try and fire right?
Any thoughts?
Also we had to change out the crank sensor for a different one, cause it broke when we tried to remove it from the timing cover, if the crank sensor was bad, would I still get spark? I don't think I would.
well got a new tune with the PATS turned off and now we get a blinking theft light and still no starting. Which is common when the PATS is turned off and shouldn't be so we are gonna turn it back on. Tomorrow we are going to install the stock injectors with stock tune and it should run cause it did before the install, we can stay out of boost or just disconnect the blower to act as though its a NA motor again so the stock tune should work for the time being, if it doesn't then we know for sure its something electrical.
We may also try a new CPS, maybe this one puked on us, who knows.
