87 Mazda w. new 13B wont start
I had the year wrong in the last post but I dont know how to delete it.
Hello everyone, I recently became the proud owner of an '87
Mazda RX-7 non turbo. It was give to me by my aunt with a brand
new 13B motor straight from Mazda, installed. Only problem is,
its never started. I am a die hard Chevy mechanic, and I spend
many days and nights wrenching on old classic cars so I figured
I could get this car to start no problem. Boy was I mistaken.
This car defies logic. It has spark, I checked the leading and
trailing coils. So I assume the Crank angle sensor is working
too. I have also checked the crank angle sensor and re aligned
it several times. It has fuel (smells like tons of the stuff)
but it wont fire with either fuel of ether. Every time I pull
the plugs, they are doused in gasoline. I assume that I routed
the plug wires correctly. The motor has an "L" and "T" on it and
so I routed L1 plug to the front L and L2 plug to the back L and
same with the trailing ones. I am gonna try to disconnect the
fuel pump and crank the living heck out of the motor and see if
that solves the problem. If that doesnt work, does anyone else
have an idea?
:
I have managed to get it to fire by unplugging the fuel pump, and
cleaning the plugs and using ATF in the lower 2 cylinders, and
using starting fluid. But as soon as you reconnect the fuel pump
it wont fire. And when it does fire on ether, it runs terribly and only
runs for a few seconds. Could this be an injector problem??

The complex starting procedure will only work if I unplug the fuel pump and use starting fluid. And then it will only run (poorly) for a few secs. is it possible that the crank angle sensor is 180 deg out? or could it be injectors? HELP ME PLEASE!!

Is there a good way to tell if the injectors are bad? I can get the car run up too about 1000 RPM, then I plug the fuel pump back in and it just quits period. I am gonna try to put ATF into the "Big" vaccum line tomorrow and maybe try to push start it.

Rebuilt engines have very low compression until they are broken in. Get a little 2 stroke oil into the engine to get it to start, and then drive it. After 100 miles if should have enough compression to start on its own.

I wish I could help. You might want to check the voltage at the fuel pump. If you search around here there is a manual for the car online that you can download. Its been mentioned on here before.
