87 22re won't start

[jjlogue3]

The vehicle:

1987 Toyota 4Runner 22re auto trans

Here is the problem:

My brother owned it and just recently turned it over to me. He said it just sputtered and died while driving.

Parts I have replaced:

Fuel Pump (only works when jumper wire is used in diag area fp & +B)
Fuel Filter
Plugs & Wires (spark checked)
Cap & Rotor (timing is on)
Throttle Position Sensor (TPS) (not set yet but i was told it should still run)

After working on it steady for the last few days (because it is mine now) I have found the the fuel pump dosn't kick on at all even when cranking over. So i did the jumper thing and the fuel pump now runs but only with the jumper hooked up but still no start. So I pulled out the cold start valve and it was very dirty so i cleaned it up with carb cleaner and reinstalled it something tells me it isn't opening as it should. Is there any other tricks I can use? I am pretty much stumped on this thing. So any help would be greatly appreciated.

Codes Thrown:

11- TPS amongst other things (cleared)
2- AFM open or short circuit
8- AFM or manifold open or short circuit (cleared)

Sorry for such a long post I wanted to eliminate as many questions as possible.

Ok I have no idea but lets walk threw this logically. There is 3 things that an engine needs to fire, FUEL, FIRE, AIR. So you know the spark is good. Why dont you pull the plug on #1 cyl and turn it over and see if you can smell fuel. If you can we can cross out fuel. You also might want to spray a stream of carb cleaner into the intake while turning it over. Should it fire then you know your fuel is the problem. DONT let it run on the cleaner once the engine fires or runs, stop spraying the carb cleaner. Also I know this sounds kinda stupid but make sure your engine is getting air, I had a firebird that wouldn't run because it sucked up a walmart bag. If fuel fire and air are all in the cylinder, then one is way off time. (SPARK) I have built a 455 recently and it would not run at all because the distributer was ONE tooth off. If you can get it to fire but not run you might want to do a leak down test, to make sure you have compression in all your cylinders. Well hope that helps.

I had a problem once where the air intake valve had become not connected.....thus not allowing the fuel to be sent from the tank. You can tell when you turn the ignition on....the pump in the tank should come on....if not.....that could be your problem. I had the whole dash apart by the time I figured it out. Just make sure the plug in at the intake is connected.....luck to ya

Are you talking about the cold start solenoid? If so yes that has been checked and it is delivering fuel upon crank. I currently have the intake manifold off to clean it up and check my injectors. I have got it to where it tries to start (cranking speeds up) but it still won't turn over all of the way. Any Ideas?

Have you tried advancing and re****ing the timing? It sounds like this might be a tooth out also.

Yes I have tried advancing and re****ing the timing to no avail. I did pull the intake manifold it is full of carbon so I might pull out my injectors and clean them.

FYI the fuel pump should only run while cranking the ignition and once the truck starts not when the key is on eng off. Does it have good spark?

I just remembered that I have run into this before........I'm sure there is likely a problem with the wiring between the air flow meter and the ECU. You need to check each pin for continuity with a meter. Before doing that check for any air leaks between the AFM and the throttle body.

air flow meter

Thats what it's called "the air flow meter". The wiring plug is has to be in for the ECU to engage the fuel pump. If you have the air filter off.......the fuel pump will not function.

The air filter does not have to be in place, but the piping between th throttle body and AFM needs to be connected with no leaks and the wires need to be connected to the AFM as well.

I just finished pulling the injectors and cleaned them up. I will go out and meter the AFM plug tonight and see what happens.
