HI HOPING FOR SOME HELP..ENGINE WONT START AFTER DISCONNECTING COIL TO DISTRIBUTOR CABLE IN ORDER TO PRIME A RECONDITIONED POWER STEERING UNIT..IVE GOT FUEL FLOW AND A GOOD SPARK..BUT NO GO SOMEHOW I SUSPECT THE ecu..IS IT POSSIBLE TO REMOVE IT FGOR SPECIALIST CHECK AND IS THERE A SPECIAL PROCEDURE FOR REFITTING..THANKS IN ANTISIPATION..PAT O'LEARY

hi.
if you are sure you have got fuel to the pressure rail and you have a good strong spark then you need to check the neg wire at the coil for a good connection as this wire feeds a signal to the ecu for switching the injectors. you can allso check the resistor pack relay which is located under the passenger front seat,the quickest way to test the injectors is to pull off one injector plug and test for a pulsing volage of 3volts dc when you crank the engine, a single l.e.d. is good for this test but an avo meter dose just as well,you should allso get a voltage reading from the cold start injector from cold its approx 5-10 seconds depending on the temp of the engine,dont condem the ecu just yet they are quite robust, but not to rule it out all together,i hope this helps if you need any more info just pm me.
