Fuel Problem. HELP!!!

[FATHER]

Hi people, my car still in my house without start the engine for a week because im waiting for the AC blower, today i receive the blower , install it and prove it, but when i want to start the engine it not start, i check relays and fuses but nothing .. I think is the pump because my fuel pressure gauge red cero also i not hear sound from the thank( i supose to hear some noise from pump??) Also i star the hazard ligths and only the left side of car work, also on cluster it not work, is the hazard flasher the problem???? PLEASE HELP ME!!!!

Any codes? Check Engine Light? It's weird that the hazard lights only work on the left side. Could be the hazard relay going.. I don't see how that would effect the car starting though.

i think is two separate problems, because i'm 90% sure that my pumps blown because i not feel it when i start the ignition, also i read some post about the flasher , so i need to buy one, to check for shorts/////my car have the check ligth on all time , bevcause i remove a lot os parts on the engine to install the supercharger

Ok i think is not the pump i check the wiring harness behind the engine and find a burn bronw wire that is ground, so for now im looking for a short circuit that cuse my hazard mafunction and the car not start. Simple question,,, in the pump relay conector at the fuse box, how many positive plugs i supose to find, because i have only one and i think is two, please anybody can chek it for me, thanks

Image is kind of small but the pump relay is the right/topmost box.

Ok i find part of my problem,,,, on all relays and fuse the red/withe wire is death is supose to go positive(12+) when i put the ignition on. So i want to check the ignition if not find probl;em i thing is some worst, any idea please!!!

Check fuse #8, that is for the fuel pump.
Then pull the fuel pump relay.



Jumper pole 30 to 87 in the socket. You should hear your fuel pump running if the circuit is ok from that point to the pump



If the fuel pump doesn't run, pull out your back seat cushion, and remove the cover on the right side under the insulation. Disconnect the plug to the fuel pump. With the fuel pump relay jumpered you shoul get + voltage at the connectors.

If all of that checks out thaen the fuel pump is ok and the problem exists on the other side of the circuit. You can see that the relay gets power from the ECM and Main power relay.



Good luck
