96 T100, showed p300, p0302, p 0304; random misfire codes for 2 & 4. Plugs and wires are quite new, clean air filter, MAF, IAC, TB, cleaned injectors, swapped coils, etc.. Was running a little better until I ran compression test. (2 very low, 4 a little higher)

Put it back together and now it starts fine then suddenly dies after a few seconds. Fuel pump relay is clicking so it's not the EFI fuse I think. Triple checked connections and hoses, found a small tear in vapor purge line but nothing else. Any suggestions?

(Also is now also showing p0773, shift solenoid e electrical.) ???

Thanks

 

Shoots! Pulled plugs again, had oil on electrodes. (??) Wiped it off, put em back and it ran for a min around the block. Parked it, let it sit and now it's cutting out again. Is this really bad??
