I have here a 5sp 9000S that has been sitting for a while but last Friday, during the usual tropical storm so popular in FL, we tried to fire it up. So, I put the fully charged battery off my 900 and we used the car fuel pump to drain the old fuel (we disconnect the feed line on the top of the fuel rail and placed it in our jug). I have to say it could be because it only have a bit over 2 gallons of fuel in the tank, but it did feel like the pump was getting a lot of air. As we put 5 gallons in the car, we may try doing (and filming) that again to see if the flow is more uniform.
Anywhoo, we then turn the ignition on. Since this is my first time trying to fire up a 9000, I completely ignored all the lights in the instrument pannel. My friend -- the owner of the car -- said some of the lights looked weird. I was concentrating on getting car alive. We then cranked the engine just to check if we were getting sparks (#1 spark plug wire attached to spark plug sitting on the valve cover). We did. Next we disabled the coil by disconnecting its primary wires, removed a spark plug and cranked again. Fuel was being sprayed out of the spark plug hole.
So, we put spark plug back and tried to crank. If we cranked without doing anything else, the engine would just turn and nothing would happen. If we played with the throttle (as in manually opening the throttle plate), as soon as we stopped cranking it would blow air through the snorkel that goes to the airbox as if it was backfiring. I can upload video of that if so desired.
What should we check for next? I would love to test for fuel pressure but do not know where to attach a fuel gauge in this car. I will say that we filled that jug about as fast as it took my 900 to do the same (I did the same feat when I first bought the car). Also on my list is to make sure all the spark plug wires are in the right order. Unfortunately I do not have a diagram of how they go in the distributor cap. Besides that, I am really at a loss.
If the fuel injectors were not so dug underneath the intake manifold, I would have pulled the rail, aimed it somewhere and made sure all injectors are spraying. Best I can do right now is grab my noid light and use it to see injectors are getting power and maybe crack open the feed line for the fuel rail to see that it is being pressurized.
