Default ka injectors won't fire

So monday i went to the local kmart. Turned of the main street into the parking lot. Before i could accelerate again the car had shut off. I tried cranking my car up for a good while with no success. I towed it home and messed with it some more. Disconnected the fuel line going into the rail and there is gas shooting out. Pulled the entire rail and injectors. Well after cleaning and making sure there was nothing blocking the fuel i hooked up the fuel lines back and tried cranking my car to see if the injectors fired. Nothing is shooting out. I have my fuel pump hard wire with a relay. I however noticed that one of the relays next to the ecu was buzzing. Well soon after the realy stopped buzzing but still cant start my car.

I know that the injectors are ground driven. And will check this weekend if the ecu is firing the injectors. Is that relay next to the ecu the EGI(fuel pump relay)? Will it matter if its no good and i have my pump hardwired? Is there any other causes that will make my injectors not fire? Bad ecu?

Car is a stock 95.

Change the relay with another and see....I believe that the ecu gets power through that relay as well as the fuel pump.

there are two relays. EGI and EGI pump. the EGI pump is for the fuel pump, and the EGI is for the ECU.

Also check the fuse labeled Engine Cont, that is the fuse that powers the injectors.

Make sure you didnt hook up the fuel lines backwards.

Check to see if you've got 12V with key on at the injector clips, if you do you've got an issue on the ecu / harness between them and ecu, if not you've got the problem elsewhere, report back and i'll help more.

weird.
you sure you didn't blow the replacement?
if there is a short somewhere that blew it the first time, as soon as you hit the key, it would have blown it again.

You sure you are getting fuel to the rail?

got a running car you can yank the distributor off of real quick? that'll let you know if the CAS is the problem or not.

Yeah i basically go over all the fuses everytime i mess around with it to make sure i haven't blown one as i mess with it. As far as fuel, i had some one turn on the switch as i held the disconnected fuel line. Dist, i swapped in a spare one i have. Still did the same thing.

But i believe i have a spare cas too. Ill try that when i get a chance and report back

So the cas was broken in half. Replacement didn't help either. I also realized that i have no spark. I removed the #1 &#2 spark plug, held them against the VC and nothing. Tried different ground points and nothing. However, when i throw in some starting fluid it'll start up but die soon after.
