I removed the air cleaner, I changed the ignition wires, started the car and it ran for twenty seconds and died. I have spark, I have fuel to the injector, but I don't think I am getting gas to the engine. I used starter fluid and the car started. I replaced the relay, nothing. I replaced the air cleaner and installed the vac hoses and nothing. There were a few wires not connected at the relay and switch (any photos of this without the air cleaner on would be appreciated,) and I don't know if they were disconected prior to my dismantaling the air cleaner or not. Any help would be great.
Check your in tank fuel pump. It should have a minimim of 3 PSI. Many were installed as a recall and there is also a rubber sort of fuel line from the pump to the tube leading out of the tank. These may crumble in you hands - so replace it with new tubing and make sure it is secure. You also may want to check the output of the main fuel pump - don' t "dead head" it - use a T fitting. Look of an optmum or around 17 PSI.

Yes I do believe that fuel is there. Are the injectors working, some time you have all but no fuel. While cranking check if power is there for injector socket.remove the air cleaner pipe the to the inlet manifold spray 2,3 puf of aero start and see if she run for few second. Take care as you spray, first spray and then start the car
If yes you can figure it out the problem
Let us know how it goes. i hope this is some help to you
Could be the main or fuel run relay located in the compartment under the luggage rack, passenger side, main relay also, fuse for the fuel relay 8amp. Electronic Control Unit is also located there.
Could be electrical, Hook up a timing light, three leads: Power, Ground, and one that goes around the wire to #1 cyl. Turn the engine over and see if there's firing. Note: u can check all 4 spark plugs this way.
Fuse lead goes to pin 30 of the fuel relay, u can jump 30 across to 57 and check for the pumps running, if not, change-I suggest both relays, main and fuel run relays. Both pumps get their 12v DC from the fuel run relay, both should be running when you switch ignition switch to on, then a tachymetric signal is fed from the coil to the relay to keep it running.
if its an 86 then it will have no fancy factory alarm ,firstly check for a spark ,if it has a spark the pour a drop of petrol into air intake ,if it fires then a least you know weither you have a fuel problem or an electrical problem with a wireing connector or something
