Have you checked/replaced ignitor/ICM

also check Main Relay (PGM-FI)
If vehicle starts and continues to run, relay is okay. To test, remove main relay, located under left side of dash. Using jumper wires, connect terminal No. 6 to battery voltage. Connect terminal No. 8 to ground. See Fig. 8 .

Check for continuity between relay terminals No. 5 and 7. Continuity should exist. If continuity does not exist, replace relay. Disconnect battery leads. Repeat measurement. Continuity should not exist. If continuity is as specified, go to next step. If continuity is not as specified, replace relay.
Connect battery voltage to relay terminal No. 5. Connect terminal No. 2 to ground. Check for continuity between terminals No. 1 and 3. Continuity should exist. Disconnect battery leads. Repeat measurement. Continuity should not exist. If continuity is not as specified, replace relay.
Connect battery voltage to relay terminal No. 3. Connect terminal No. 8 to ground. Check for continuity between terminals No. 5 and 7. Disconnect battery leads. Repeat measurement. Continuity should not exist. If continuity is as specified, relay is okay. If continuity is not as specified, replace relay. If fuel pump still fails to operate, test main relay harness. See MAIN RELAY HARNESS under FUEL CONTROL under FUEL SYSTEM.

Check for codes ..and let me know .. count flashes ...

RETRIEVING CODES
With ignition off, insert jumper wire in service check connector terminals, located behind right side of dash. See Fig. 1 . Turn ignition switch to ON position. Diagnostic Trouble Codes (DTCs) will be indicated by a series of long and short flashes on MIL. The number of long flashes indicates the number in the 10s column. The number of short flashes indicates the number in the 1s column. For example, 4 long flashes followed by 3 short flashes would indicate DTC 43.
