recently bought a signum 2.2 with the z22yh engine all was fine then the other day it just would not start.
the only code i am getting is P0190 FPR circuit A high/low intermittent. at first due to all the posts i thought that it was the semiens fuel pump as when i took it off there was a lot of oil between the engine and the seal on the pump.
i have re-seated the seal and refilled the pump with hydraulic oil, and i am getting good pressure out of the fuel union fitting. i know this wont last long but i thought it was worth a shot to see if the car would even fire up.
nope still getting the P0190 code.
engine turns over fine, sparks are good but the car wont even fire up with easy start.
timing chain seems good and when the crank pulley is aligned with the marking on the timing chain cover the lobes on the camshafts of cylinder 4 are pointing upwards as per hanynes manual.
is there a way of checking to see if the chain has jumped 1 or 2 teeth??
i have used an endoscope to look in the cylinders and nothing points towards bent valves.
this car just wont fire at all even if i start disconnecting sensors like FPR /FPS/ Cam sensor it wont fire into limpt mode either. Any pointers or ways of testing would be great as i dont want to go buying replacement parts without know what i need.
