I've been working on trying to get a Bertone X1/9 running and I have come across a problem. Here's a synopsis of what I know:
The fuel system is working: good fuelpressure and flow, and there appears to be appropriate fuel being returned to the tank from the pressure regulator.
The ignition appears to be fine too, since the car starts up easily and runs smoothly for a few seconds, but then fades out. If the ignition was an issue, the engine would either not run, run roughly or just quit abruptly, which it
does not.
The fuel injection also appears to be working okay as
indicated by the smooth engine operation, at least while the engine is
running.
It appears to be an engine computer issue. Apparently, the computer
begins sensing various engine parameters a few seconds after the engine
is started. Then, I am guessing that it must be leaning out the
fuel/air mixture to the point where the engine can no longer keep
running.
I notice that if I pump the foot feed right after starting the
engine, it will run a bit longer than if I don't do this, but it still
quits after just a few more seconds.
One guy I heard from thought it may be the air intake sensor, which is
basically a vane in the intake manifold that moves when air is sucked
into the engine. The engine computer then regulates the mixture based
on where this vane is, and if the vane and/or sensor is not working
properly, incorrect information is sent to the computer which results in
an incorrect fuel/air mixture.
I have not had a chance to check this out, nor do I really know how to test this sensor to tell if it's working properly.
If anyone knows anything or has any ideas I sure would appreciate it. I really want to get this thing running. It looks like a real fun car.
