2600i sohc 12 valve problem

when you star the truck you have to give it gas to keep it running til it gets warm or if you just let it start it sound like something like a solenoid or sencor click and shuts the motor off, also even when its warm the motor wont go over 3000 rpm or it will just bog down. whats the problem? help me out guys!

check and make sure your fuel systemis working properly,
filter (new or clean), pump is pumping, and fuel rail isn't
cloged. some of the other guys w/ the 2600i's might be more
helpful, but it is a place to start.

Has your ecm ever been repaired? These Mazdas, including my 90 B2600i, are known for having ecm problems. I used AVPro to repair mine.

how do i get ahold of avpro? what does it cost to get the ecm fixed? how do i determine if its the ecm?

I think their web site is avpro.com or do a search for avpro. I paid $150.00 with life time warranty.

on the passenger side fender well there is a relay that all the fuel lines run too right next to the charcoal caniter, what is that? that is what keeps clicking and trying to shut the motor down.
