I'm kinda confused on this one. The car has been sitting for about 3 years with just the engine put in and nothing hooked up. Finally got everything back together, and I can get it to run for a few seconds by lifting the air plate.
I'm testing pressure with the gauge hooked up as so:
With the valve closed pressure is close to 80psi. With it open it starts around 20-25 and rises to about 50-55. That seems to be a bit high for only being 50 outside and colder overnight, but I don't see why it wouldn't run.
The engine seems to rev quite after a second or so when it does run, and seems to stop kind of abruptly. I can't find any air leaks and have almost all the vacuum lines capped for now.
I can hear the frequency valve buzzing, and the spray pattern is good from all 4 injectors when I lift the plate. At this point I'm a bit stumped, I could really use a second opinion!
