Come on yous Volvo Guys, I need help. I am helping a very elderly gentleman and I am just elderly. I've had only two responses to my plea of 29 June.
Again: 86 Volvo 240 GL SW. The timing belt broke at 120K. Yes, we checked compression to all clinders and they were all to spec. The belt was replaced but the markings for alignment were not as clear as on prior models. Black plastic belt housing as opposed to the aluminum. Finally, got it right, but it would not start with no spark. Finally, resolved problem by a change in the fuel pump relay. We were able to get it started and timed to 12+/- 2 TDC with timing light. It purrs at idle. So to the road but upon accleration beyond 5 miles per hour, it dies.
Have checked and cleaned both intank pump as well as main pump. New fuel filter. Have checked pressure at the rail and it is to spec. Have checked the injectors with ohm meter an all is well. Have pulled plug wires individually from spark plugs and no change inthe idle. Finally, I cleaned the throttle body throughly as well as taped all holes in the hoses leading from the Air Flow meter. It will die at idle if I disconnect, so assume it is ok. We then changed the fuel pressure regulator, new one, and no real change.
Question: If it times out perfectly with timing light, can I still be off by a notch in the timing? Or is this strictly a computer chip problem or a fuel problem. I tried all 42 pages of the FAQ, but no real help.
Who can lead two old blind men out of their morass? Also, what is the web site for the Sweden connection experts? I can't find it.
I have worn out my Hayes manuel plus the Mitchel. I do not have access to a Volvo Shop Manuel. Local Dealer is multiple car rep and service manager can not be too helpful over the phone. Were too poor to take it in for a diagnostic run.
Thanks again, if not for advise but the reading of the missle.
Please note, I didn't have time to Spell Check..RockyDoc
