86 240 won't start, air mass meter? 200

Hello- I am hoping for some quick advice before I have her towed to the shop. . . My car was running fine. . . .it sat for a few hours and then would/will not start. The motor turns over fine and even runs for a split second but immediatately stalls. This can be repeated over and over again. There is fuel in the tank, fuel pump is humming and all four plugs produce spark. The plugs do look a bit dark upon removal. Also I do smell a bit of gas in the cylinders There are no obvious problems with the intake tract. I performed the electrical tests for the LH 2.2 as described in the Bentley manual and came up with two anomolies. The airmass meter's "heated wire" resistance was 2.9 ohms instead of the 3.5-4.0 range specified in the manual. Also the red wire (#16) on the computer connector that hooks up to the AC mircoswitch always reads continuity to ground rather than the books spec which is no continuity with the AC switched off and variable (As you turn the knob) resistance with the AC switched on. I am more suspicious of the Airmass meter than the ACmircoswitch but who knows. Any thoughts would be greatly appreciated
