Will it turn over but not start or not turn over at all? Also is that a tuned port injected engine?

Its a tuned port injected engine and yes its turns over just fine.


Ok. When you turn the key to the on position do you hear the fuel pump prime for about 2 seconds then stop?


Need to figure out what's missing. Fuel, fire or air. Check fuel pressure at fuel rail. I believe your test port for fuel rail is on the back passenger side of the fuel rail. Looks like a metal tire air valve. You should have 36+psi - 46 psi there when you turn key on and it primes. If you do not check fuel pump fuse and fuel pump relay. If you do check spark plug wires for fire.

Thank You so much.

Would you please tell me where the fuel pump relay is and also the fuel pump is. No fuel in fuel pump rail its not kicking on.

Nevermind I found it


Your relay should be located on the drivers side firewall by corner of hood I believe. The fuel pump is in the tank. And you should be able to hear it hum when you just turn key to the on position(not start) will only hum for about 2seconds. If it don't check the fuse first.

Thank You for all your help. I hope to have it fixed today. Have a good day.


Oh and on some models(not sure about yours) there is an oil pressure sending unit that works in conjunction with the fuel pump relay. If it's not reading at least 8psi of oil pressure the fuel pump and injectors will not operate correctly during start up and normal operation. It's located on drivers side right be side the dist. In the picture it's the item with the two orange wires. You can unhook it and put jumper in electrical plug. If it then starts replace the oil pressure sender.


Just keep in mind that the fuel pump will still prime even if oil sender is bad.
