No Error Codes Problem

Stalled while driving, starts but just barely runs then stalls after 1 minuite or so, will not run at all otherwise. Error Codes read 12 as usual followed by 3 sets of 3 short flashs which I interperted as no error code? Checked ICM for carbon, is clear, checked MAP-checked OK, fuel presure 48 PSI, I believe any where around 50 PSI is OK?, Checked vacum lines but have no gague at this location, every thing looks secure. Crank Position sensor was replaced about 2 years ago. Any help you can give me would be greatly appreciated. A weekend mechcnic who is stuck out of town. Just had ignition module tested, module tested OK, all coils OK, still have same problem, Will be testing every possible sensor that I can.


Thanks in advance

Only things I can think of are the igniton module and crank sensor. Might want to get it tested again at another place. I am told these tests are not always conclusive as heat will cause them to flare up, but sometimes will not show up when out and no longer hot. I think NAPA has better test equipment, but that is my opinion.
