v6 camry now won't start

[dakota1205]

My car is a 94 camry, but has a 96 1MZ-FE engine from a avalon. Bought used and has been a [COLOR=blue !important][COLOR=blue !important]great [COLOR=blue !important]car[/COLOR][/COLOR][/COLOR] for ~3 years. Just hear last couple weeks, it would start running and idling rough for a few minutes at a time. The last time I drove it home, it completly stopped on me on the side of the road. It finially started to make it home and now have in the garage. Now it will crank, but won't start. After you crank it, shut iginition switch off, then back to start position, you get a pop out the exaust pipe. From these forums and my haynes manual, I've checked the camshaft sensor, it appears ok (1.1k ohms), crankshaft sensor (2.0 k ohms), 3 of my coil packs, front side (1.4 ohms) manual says .5 to .85 ohms, so i'm not sure about this, the mass [COLOR=blue !important][COLOR=blue !important]air [COLOR=blue !important]flow [/COLOR][COLOR=blue !important]meter[/COLOR][/COLOR][/COLOR] (2.9k ohms), and it has the 5 volts to it, coolant temp sensor (2.3k ohms), replaced this last year. I haven't checked [COLOR=blue !important][COLOR=blue !important]fuel [COLOR=blue !important]pressure[/COLOR][/COLOR][/COLOR], since I have to go rent a tester. But I am running out of suggestions. Hope someone can point me in the right direction.
