Volvo Repair: starting problems 1990 240DL, flash flash flash, example 121

Question
I have a 1990 240DL wagon...it has been having some problems starting.  It turns over....but needs some gas and sometime a couple of tries to be able to continue running.  Once it has started, it runs just fine.  No stalling either.  I checked my air filter and it looked really clean.  What else can I check?

Answer
first would be to check for any diagnostic trouble codes.below is how to do so.



in the engine bay on the drivers side near the strut tower there is a small black box with a wire attached to it.place the wire in the terminal marked 2.turn ignition key on (not started)press the small button for 1 second and the code will be displayed as a series of flashes.a red led displays the codes.the code will be three digits.small pause in between flashes for a single number long pause between flashes for the next number.example 121 will be flash.....flash..flash.....flash.repeat three times or until first code repeats itself.to erase the code after all codes have been checked hold the button for a good 5 seconds then release the light should light steady,then press for another 5seconds.this will erase the codes.  email me the codes and i will tell you what they are..socket 2is the fuel system 6 is ignition.
