EFI Problem. Not Starting

1985 camry 2S-E Engine.I bought this car from a good friend of mine and she stated it would not start. Well come to find out it was running before it died and it wouldn't restart. Well I got it home and started to look at reason's why it wouldn't start. I've replaced the dist cap, rotor bug, plug's and wires and still won't start but i've got fire to the plug's. I've checked the fuel filter and it has pressure, i've checked the injector pigtail's and it has 12 volt's so I know the efi relay and fuse is good. I've used starting fluid and still not wanting to start but when I 1st hit the key it hesitates then it act's like it's not getting fuel to the plug's. The injectors aren't even making noise. But the fuel is getting in the fuel rail as normal. I've even checked to see if the intake port was getting air by placing my palm up against the tube and it's working. So i'm wondering if it's the injectors or the timing has jumped a tooth. Car has 180,000 miles. Would this engine have a belt or chain
