OK you have tested the coolent sensor...thats fine...when you get the new timer do check each colure wire is on the right terminal...on the Timer you should see a leter " G & W "....G.will be original ford colure "Brown & white ".... W will be " Black & yellow ".........Pressure actuator colurs Brown & Black / yellow...leave that plug off for the moment as with the new timer it will nice to see the 5th injector come in...ie burst into life right away..sound on all 4 cylinders...but yes cut out i would expect.. lets take it stage buy stage at moment...if dont see "W & G on your new timer as even back in the day...i remember some were not...so will tell you how to find out if required later.. will cover the actuator later........Peter
