The 4runner hadn't been started since November when the Alternator and battery went, at that time a battery had been connected negative-positive for 2 seconds and car loss all power. In late january i replaced the alternator, battery, and alternator fuse. CHANGED oil and coolant as well. Has power, turns over but wont start, knocking noise in air intake. Has fuel and spark
Knocking noise in the air intake or do you mean a lifter noise,because you let it sit the lifter are not charged up or solidified,so you dont get adequate compression when you turn it over.if you have fuel and spark thats fine what about compression,noise from the air intake make me wonder if the timing belt is intacted.
SOURCE: 92 totoya 4runner wont start turns over> no spark
you probably moved the distributor out of the proper timing
SOURCE: 1990 toyota pickup wont start/turns over no spark or fuel
there may be a bad contact problem check the wire running into the fuse box and look at the relay for the efi

difficult one this anfd i do hope more experts read it and have a think about it ,now engine will run with ether spray ,or petrol down air intake so the problem has to be fuel related ,so firstly check for fuel pressure into the fuel rail ,on the end is a car tyre like valve so push this down and check the pressure to see if it squirts ,if it has pressure then use a meter to check the current to the injectors but as its a pulse then use a dwell meter or a scope as i think the ECU could be damaged and its not pulsing the injectors to make them open allowing fuel through ,but i could be wrong of course ,it may pay to have the ECU repaired in specialist company to eliminate this as a source of your problem .
SOURCE: battery went dead changed it
Hook the battery up or try to jump-start backwards did we?
The ECU fuse gets it's power from the 140 Amp (or 180 Amp, depending on which engine your vehicle is equipped with) ALTERNATOR fuse in the engine compartment fuse block.
