86 runner no start issue

[LODI QUACKER]

The thing just quit running. I have changed several things to include the fuel pump. Starts like its great, then immediately dies. I have power at the fuel pump at start but not when you let go of the key I guess the on position.


Help please...

Could have something to do with MAF or COR.

WARNING: PROCEDURE BELOW IS FOR TROUBLESHOOTING PURPOSE ONLY. Not meant for normal operation.
Try this and see if it keeps fuel pump running while Ign is on:
If you suspect MAF malfunction or to test IF fuel pump is working, with Ignition ON, jump terminals of Fuel Pump Check Connector (below. brown and green wires lead to connector). This will bypass MAF contacts and connect fuel pump directly to 12V from EFI relay. You should hear / feel fuel pump run.
