You can see the fuel dots that is squirted on the paper.
If one to 3 are not squirting, you have bad injectors, if all 4 not squirting, then most likely bad pump.
And that is the Tech of the day~ How to check the Fuel system and diagnose the source....Bet no one thought about that huh!
KA injectors go out commonly. I replaced a lot of them in my cars.

This is generally a bad idea, because those O-rings are tricky, and love to leak. Who does diagnostic work without a voltmeter?
OP - I guess you fixed the problem? To wire in a standard "Bosch-type" relay instead of the relay from the car, hook it up like this:
85/86 - one lead to +12v power, the other to the black/pink striped wire off the ECU harness.
87/30 - one lead to fused +12v power, the other to the black/yellow wire coming off the fuel pump.
Then make sure the pump is grounded well, and that's it! Do you know for sure the stock relay/relay wiring was the problem?
