on yours it was T2? Did you just replace the transistor to get it back
up and running?

The relay has 12 volts applied to one side of the coil with the
ignition on. When you jump F/P to GND you are taking the other
side of the relay coil straight to ground bypassing the
transistor. Normally the transistor performs this grounding
function (sinking current). T2 also interacts with other circuity
in the MAF box.
This happened to me about 4-5 years ago on my '92.

When I jump out the F/P to GND the pump stays on but I still have
the same symptoms. If that transistor drives the relay but I jump
it out should that not run?

Hi Eric,
I sent this out earlier but didn't see it repost. I apologize
if its a repeat.
There is a transistor in the Link box that replaces the AFM;
it drives the fuel pump relay. It is an NPN transistor, is
marked "T2" and may have failed. About $1.50 and a soldering
iron to replace.

I just swapped out the CAS and same symptoms. If it's a bad
MAF box where can I get one of those? Since my Baja went
down the Miata has been my only transportation and Kaitlyn
and I are leaving in a week and a half for the dragon and
our road trip.

Can also be that one of the two signals from the CAS is
not there.

Just checked that connector. It looked fine, I reseated
it and still have the same symptoms.

Have you checked the manifold pressure connection
(heck! I think that's what its called - I can't
remember!) ? If it comes loose, it may begin to fire
and then die. On mine its the small box with the
AFM-like connector (multi-pin) on the driver's side.
