Check your fuel pressure. Just because you hear it doesn't mean it's working correctly. It could be giving that initial pressure then dumping.

When I turned on the key the fuel pressure was about 62psi when the fuel pump shut off it went to about 58 and it was like that the rest of the time. If the pressure was good then that means that the relays are also good right? I thought that it might be the oil pressure sensor but I can not find the thing. My guage on the dash shows that the oil pressure comes up but that does not mean that the sensor is good right?
I dont know what else to do so thank you for whatever help you can give me.
