HELP!!! TACO WON'T RUN AFTER MUCH TESTING

Well I have no way to get the truck there, and I doubt he will let me barrow an ecm :/

 

What about a vacuum leak use that brake cleaner and start spraying around the edges and hoses and see if it revs like mad

 

Maybe theres a vacuum leak use that brake clean and spray around the intake and air cleaner and see if it revs like mad. I guess after you unplug the maf since thats the only way to get it to run

 

I think I may have found the problem but no garuntee. If it's correct I'll share thanks for the suggestions!

 

Bump is it fixed

 

Going to get maf cleaner and vacuum hose now will update tonight

 

Ok SOLVED I know you guys will shake your heads at this one, but first and foremost let me say i am used to working on hondas and carbureted motorcycles. I have knowledge of MAF sensors but NEVER have i seen one as sensitive as these early platinum sensors. The whole thing that struck the idea Was this video...https://www.youtube.com/watch?v=7Ht6P0Et79o

On previous Hondas i have worked on, never has the motor STOPPED RUNNING COMPLETELY AND FAILED TO ACCELERATE PROPERLY simply due to vacuum leaks. As the video explains too much of a vacuum leak causes the car to stumble with little to no acceleration etc. Since i don't have a/c and it was removed i didn't see much reason for the Idle up solenoid, plus one of the inlets were broken so i removed it not plugging the holes to the manifold. I will also add on the early 2rz manifold their were two inlets instead of one on the right side of the intake. since they were not blocked off this caused a large enough vacuum leak to completely shut the car down and prevent it from running because the air being inducted through the manifold inlets were not being measured by the maf, so it was reading way too lean with not enough fuel to compensate. ....I've never seen a vacuum leak have such a large affect on the performance of an engine. I mainly think it is due to how sensitive these maf sensors are specifically. I'm sure most of you have heard stories of people putting a k&n intake on and the truck runs terribly. This is apparently due to the fact that if you don't have the shield protecting the air filter the cooling fans can actually blow air into the intake and The MAF will measure it even though this volume of air is not actually being used by the engine it will run rich and flood I'm assuming. This could be myth, but it is just what i have read. So glad to have figured this issue out. provided is a pic of the manifold ports i was referring to.


I would also like to apologize for my ignorance of vacuum leaks like i said im used to carburetors and with those and a vacuum leak the most you get is a high idle....

Thank you guys a lot for your help! So happy we figured this out.
