311runner

I have a 1995 toyota 4runner with a V6 3vz-e engine, i got the truck in January. A couple months ago i started noticing the truck was hard to start when the engine was hot and the problem kept getting worse until it wont start any more. Everything electronically works still and I'm still getting 12 volts from the battery.

Things i have replaced:
-Fuel Pump
-Mass Air Flow Sensor
-Circuit Opening Relay
-Fuel Pump regulator
-Spark Plugs

Things i have checked and turned out ok:
-ECT sensor
-Cold Start injector and cold start injector time switch
-VSV Fuel pressure control sensor
-oxygen sensor
-EGR gas temperature senser
-Throttle Body sensor

I have another thing to add that is confusing me. I have spark coming from the Primary ignition coil, but when i check the resistance of it said 3 ohms and the toyota manual said the resistance should be between 0.36 ohms to 0.55 ohms. Do you think the spark plugs are not getting enough spark to light the fuel or do you guys think its something else?
