87 4runner electrical fuel injection problem

My truck has been off the road for over 2months I cant figure out whats wrong with it. ive replaced multiple sensors including maf, throttle sensor, air valve, coil with the igniter, and ive checked multiple relays. i am at the point where i dont know what to do. Ive taken it to 3 ''Mechanics" and one can even tell me whats wrong.

Hi Vega2837, first you gotta tell us what's wrong. What is your truck not doing?
A problem well-stated is a problem half-solved.

Pretty simple I get this alot!!

It is broke.

How did this start or did you buy it in this condition??

Have you done a 3.4 swap??

Because the 87 only came with the 22R series engines.

And the had a AFM.

Not a whole lot of sensors would keep that engine from running either

I would have to guess your injectors are not opening because for some reason they are not getting the signal.

Bad ground

open harness someplace Hacked wiring!!

The magic smoke has left the ECU to join Elvis

Then again maybe the gas tank is empty

If you changed the coil and igniter your trying to fix a no spark condition what about the wires and plugs any or all could cause a no spark condition

Maybe you just have that effect on mechanics I know i do They just get all glassy eyed and mumble about harmonic balance and Karma catching up with them.
