1997 vitara

[1972]

iv done a compression test cold 180 185 throttle wide open. check valve lash all good. i have replaced the timing belt (gates) water pump crank key and timing cog and crank bolt, tightned to fsm spec. i checked today just to make sure its still timed correctlt. my scan tool can read live data etc, but now i know why i cant switch to obd2, it says ecu connection broken, thanks for that other wise i would still be scratching my head, Ill definitely get underneath and have a look at the fuel lines, i know i smashed the rear gear box cross member mount,  again !. i have also replaced the fuel filter. im waiting on the fuel pressure tester to arrive. ill disconnect the fuel return line aswell to see if its blocked to. i did notice that when ignition is turned on there is a pressure whining noise which gets louder before fpr cuts in. its coming from the engine area. the car is idling terrible and is slow to rev. once above 3000rpm it starts to smooth out but not free reving if you know what i mean. the spark plug gap here 1.0 / 1.1 mm our no 1 igition lead on distributor is at 11 o clock not 1 o clock like the usa as i noticed on your specs. There is no cat i checked when fitting the headers, looks like the previous owner knocked it out. thanks again your a wealth of knowledge
