Well, you've given us a million and one possibilities. You're going to have to rule out whether you're missing one (or more) of three things: air, fuel, or spark.

I think it is a fuel problem,i pulled 2 plugs they are not wet.Using the haynes manual i did fuel pump check,and checked ohm on cold start injector,I also checked ohm on air flow meter everthing looked good except between E2 and THA it says i should have between 2-3 K but i have nothing could air floe meter be the problem? If it were faulty would motor fire but not run?

Yes. During start up the ECU provides a preset amount of fuel. After start up it will switch to the MAF. I learned that after a head gasket job on my truck. I wasted a whole afternoon checking cam timing, spark, fuel etc. before I found the loose connector. Talk about feeling like an ass.
