Question about 1999 Ford Windstar
Scanner gives code no cam position output signal to the FICM and sometimes no crank signal code. I have replaced both cam and crank position sensors I can see on the snap on vantage occiloscope that the PCM is receiving both crank and cam signal and is sending the signal too the FICM . I have replaced both PCM and FICM with known good ones and the same codes remain. I can crank motor over and after a very long time the snap on scanner will read SYNC yes and then no , after charging batterys and cranking motor over long enough that I figured the starter was going to melt down it did start and set a cylinder distribution #4 fault. after turning ignition off the only way too restart is crank for another 30 to 40 seconds. when running seems to run ok. when cranking the scanner shows controll preasure above 600 fairly quickly. I also did replace the control preasure regulator. when I began working on this truck it would not do the injector buzz test because the controll preasure was reading 900 KOEO. after unplugging and replugging conroll presure sensor it went to zero then it did the buzz test and set no codes. I have cleared the codes many times and it resets the cam position output sensor code every time , I know without a doubt the signal is there. there is not a security issue that I am aware of I have been working on this truck for about five weeks , and dont want too give up but I have done every thing I can think of , If I was rich I would pay someone 1000 000 000 dollars to fix this but I am not.I have tryed our local Ford dealerships and they have no clue what the problem is any help would be greatly appreciated thanks
Forget any Ford Dealers, you need to find a shop that Specializes in diesels. You should be able to find one in you area. Any shop that does a lot of light diesel truck work should have someone with the knowledge to get you going. Call around to a few shops and see who they refer their "Problem Child" diesels to.
