My fuel pump will only work with the green connectors together (near the ECM) and pulse on and off (test mode?). What should I do next?

you ask

"What should I do next?"

 

 

not to be a jerk, but you might want

to detail the problem a little bit more.

Have you checked that spark is getting to the plugs? The pump may not run if the system does not see ignition pulses.

if you do not see fuel at the injector chances are the distributor is bad.

 

i just put spfi together, no spark or fuel, used a different disty and all good

 

check the engine code procedure described in the usrm>miscellaneous

I get good spark and engine runs briefly. The ecm blinks 1 long two short then repeats. I have hooked up the fuel pump directly to battery (both ways, I hope that didn't mess it up) It still won't start. Thanks for you input! This vechicle has been sitting for a long time, but ran good then. I have drained fuel, and added fuel system (water) cleaner and injecter cleaner.

I would try pouring a little gas down the throttle body. That should give it enough gas to fire a couple times, and allow the fuel pump to get fuel to the engine.

 

The 1985 FSM says that code 12 is the starter switch. Check pin 9 on the ECU (Black wire with White stripes) for 12+ V when the ignition is in start. (There should only be one wire that is black with white stripes going to the computer)

 

If it is an automatic, there may be a problem with the inhibitor switch, otherwise the harness is open somewhere.

Thanks for your input!
