156 Starting problems
Several months ago I found the EGR valve jammed solid due to a seized solenoid. I removed the valve, cleaned it up, and got a solenoid from a Vauxhall EGR that looked identical. Tried it, and it worked, but the engine became a bit stuttery on accelleration. Fuel economy fell, so I disconnected the solenoid and everything returned to normal. I haven't touched it since then. Haven't had time to investigate due to work committments and holiday, so i'll have another look to see if the EGR is open.
As for the fuel pressure relay, I'm not sure how to test that. Would hooking the car to a diagnostics unit be able to tell whether the fuel pressure is holding when stopped? If so, is there anyone in the Lincolnshire or Loughborough area that could do a check for me?
