Fuel Injector Test 850

posted by  someone claiming to be Tommy on  Tue Dec 13 22:24 CST 2011 [RELATED]

I currently have a no start situation with my 94 n/a 850. I purchased the fuel injection light tester from IPD http://www.ipdusa.com/products/5625/109198-fuel-injection-test-light It looks like the light should flash when I crank the engine, but when I test my injectors the light stays on continuously, no flashing. Can anyone tell me what this means and if there is any solution.

Thanks......Tommy

It may mean that the injectors, like the older 740's, have voltage to them all the time the ignition is on but that they only open/fire (flash) when the the computer connects the ground. The lack of injector fireing may mean the camm position sensor is bad. If the camm sensor doesn't send the computer the signal the engine is turning over it won't ground the injectors.
