. Ensure you test all under-dash and under-hood fuses with a test light or multimeter:

. Ensure main relay works properly.
. Ensure ECM is good.

The main relay comprises two relays. Its first relay controls voltage to the ECM, power to the fuel injectors, and power to the second relay. Therefore, test all fuses, run the K-Test on the ECM, and confirm you can hear the main relay click. Be sure and answer the 3 basic diagnostic questions.

Have you checked the ignition switch? When you first turn the ignition key can you hear the fule pump? Good luck.

Well man I had that problem before mine was a 89 I changed the motor out and it would turn over and start and then die immeditly there is a ground wire that is in the wireing harness I think it is close to the transmission if it is loose that will cause it to do that you can also look at your computer there is a red light that will blink if there are any trouble codes you just count them and then look in your book and it will tell you what each blink is for hope my advice helps you
