Installing used engine(2.7L 4-cyl) in 97 Tacoma ext cab. Old engine has coil pack/s - used engine has distributor - will the distributor engine be compatible with wiring - will it work or can it be made to work(wiring conversion kit)?

Not a difficult job, but difficult to outline without photo/video aid.
Short list, using compressed air, blow out all of the junk that has collected under the intake muffler, then remove the muffler from the throttle body and airbox There are two large hoses, plus two small hoses, one on the rear (crankcase vent) and one in front. There is also a wire harness on the rear that needs to be separated.
Once removed, make sure the top of the cam cover is clean, unplug the wiring harness from the coil packs, remove the bolts (10mm socket), and pull the coil packs from the plugs. The rear plug is a bit of a pain because of the wiring harnesses, but you can carefully separate them and move them out of the way.
The Tacoma 2.7 uses Iridium plugs. Stick with the OEM Denso plugs, don\'t fall for the snake oil salesmen pushing 4 electrode or special "hot spark" designs.
The firing order is 1-2-3-4-5-6
Cyl #1 is front left when looking at engine front to back
left coil pack connects to cyls. 5-2
center coil pack connects to cyls. 3-6
right coil pack connects to cyls. 4-1
It doesn't matter which connector on the coil you use just that the cylinder is connected to the proper coil pack (the coil fires both plugs at the same time, twice per each full 4 stroke cycle)

Well the 4 cyl engine uses a coil for each cylinder, and the 6 cyl uses one coil for all 6. Both systems use signals from the engine computer to fire the coils. So the RPM circuit would involve the engine computer. No distributor is used.
No distributor listed. Looks like it uses two 4 cyl coil packs, one on each side of the engine. Follow the plug wires - the module is part of the coil pack. Could be a relay, or the pump. You'll need to figure out if it is lack of spark or fuel to proceed.
Hi there: Misfire #1 or #2 cyl means DTC P301 or P0302 fault code.
A code P0301 or P0302 may mean that one or more of the following has happened:Faulty spark plug or wireFaulty coil (pack)Faulty oxygen sensor(s)Faulty fuel injectorBurned exhaust valveFaulty catalytic converter(s)Running out of fuelPoor compressionDefective computerPossible Solutions
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
On the V6 engine The drivers side plugs are easy although the passenger side will require you to remove the intake boot and the coil packs, easily done with a 10 mm socket and ratchet. Disconect the coil pack connectors by depressing the plastic clip and pulling them off one by one on the three coil packs . leave the plug wires attached and pull the coil pack straight up and off the spark plug.Blow out the area around the plug with compressed air to prevent debris from entering engine when the plugs are removed. Use a 5/8 spark plug socket and a 8 inch extension bar on your 3/8 ratchet at remove the plugs. use anti seize on the new plugs, gap the plugs to manufacturer specs and install your new plugs 2. If its a 4 cyl engine its actually a bit more difficult. The intake boot assembly has a bracket that bolts to the valve cover and side of the engine and you must remove it to access the 4 coil packs on top of the engine. once again the coil pack wires must be disconected and the coil packs un bolted and removed from the valve cover to access the plugs. Blow all dirt from around plug with compressed air to prevent foreign objects or dirt from entering the engine when you remove the spark plug , once again use a 3/8 ratchet and an extension with your 5/8 spark plug socket and remove plugs, use a small amount of anti seize compound on the threads of the nes plugs and gap them to manufacturer specs before installation. Also while the coil packs are off,, Inspect them for ARC Tracing a white residue and line may form on the coil pack Tip/boot if you see alot of ARC tracing Id suggest replacing that coil pack. Especially if you have a misfire condition.
P-0304 indicates number 4 cylinder misfire. Are you using Toyota parts dept spark plugs? More often than not, non-toyota plugs make the v-6s run poor, right out of the box....
Try this:With the engine running, pull the connector wire off of the #4 injector. Note to see if there is any change with the idle quality. No change? You may have a bad injector.
