Hey guy's,

Believe it or not, I still have not got the damn race car to fire up. After checking everything that had been previously suggested (and More), i put it on hold while working on other areas of the car. Now it's time to get serious......

We have tracked the problem down to the wiring of the injectors (we think)..... the car will start on Aero start, we have good fuel flow to the rail, and it is holding pressure at the rail. The injectors have been tested and are fine (Bosch Motorsport 550cc). I have had someone who knows Motec help set the CrIP, which is shown in the car firing on the aero start.

Here are the current symptoms......

1.When you first crank the car, it goes to fire...sounds very promising, but after that is basically dead until you turn the ignition off and then on again (resetting the Motec). When you try to crank after restting, it does the same, tries to fire initially...then nothing.

2. When doing the diagnostic test...... the injector will test OK for about 2-3 seconds.... then a weird message flashes on the screen. The messages says something about being unable to test due to the engine running?????? Which of course it is not.

3. All injectors have been tested while cranking, and all of them are pulsing.

The question is....are the first two symptoms related?...I think they are.

Has anyone come across this before, or know what may be causing this?

We have also tried increasing the Overall trim on the fuel...right up to 50%. The result on cranking was the same. We checked the plugs...and they did not show signs of bathing in avgas....which should have been apparent with 50% overall trim added. They did show signs of fuel getting in there, but I think this is from the initial cranking...... and then for some reason the injectors are not doing there job.

Sorry for the long post..... any help will be greatly appreciated. This thing is driving me INSANE!
