Expert:  david craig replied 3 months ago.

do you mean the square ones with the plastic top?

Customer: replied 3 months ago.
The blocks about 1 I inch square there are several smaller fuses that have clear top can see. They are not burnt
Expert:  david craig replied 3 months ago.

you are talking about relays then......

Expert:  david craig replied 3 months ago.

you're going to have to check the fusible links ad all fuses in the engine compartment. check the battery positive wire going into the fusebox. check any smaller ground wires that may have been damaged on top of the radiator core support, right and left fenders inside the engine compartment

Expert:  david craig replied 3 months ago.

pull the fuel pump relay. jumper across the contacts 30 to 87 and see if you hear the pump run.

Customer: replied 3 months ago.
I assume you want me to jump a wire across the plug how do I identify theese numbers are they on the plug? Should I just replace the relay?
Expert:  david craig replied 3 months ago.

ok. you will have to pull the fuel pump relay. with your meter, probe each position of the relay base til you find 12vdc. no other position should have voltage. then turn the key to the run position and look for 12vdc on another position on the relay. you will now have 2 positions with voltage and 2 without. take a jumper wire and jump from one of the positions with 12vdc to one without, and listen for the fuel pump

Customer: replied 3 months ago.
Not going to mess
With
Car tonight gong to watch debate
Expert:  david craig replied 3 months ago.

ok

Customer: replied 3 months ago.
Jumper wire can hear fuel pump but car still won't start also part stores here don't have this relay
Expert:  david craig replied 3 months ago.

its not going to start as long as that relay is out because the other 2 positions have to complete the circuit.

Customer: replied 3 months ago.
Need new relay?
Expert:  david craig replied 3 months ago.

What are you thinking? Looks to me relay not working weird coincidence
Expert:  david craig replied 3 months ago.

when you checked for power at the relay did you have 12vdc at 2 positions with the key on?

Customer: replied 3 months ago.
Think so but will re check
Expert:  david craig replied 3 months ago.

ok. let me know

Customer: replied 3 months ago.

Customer: replied 3 months ago.
Think so.
Customer: replied 3 months ago.
Got to go to work
Customer: replied 3 months ago.
Should have one wire hot only with key on for fuel pump or it would run all time
Expert:  david craig replied 3 months ago.

no, with key on you will have 2 hot

Expert:  david craig replied 3 months ago.

with key off only 1

Customer: replied 3 months ago.
2 hot all the time
Expert:  david craig replied 3 months ago.

then change the relay.

Customer: replied 3 months ago.
Nothing telling relay to close
Expert:  david craig replied 3 months ago.

the relay isnt opening. if it has power on 2 all the time its closed all the time.

Expert:  david craig replied 3 months ago.

possibly stuck

Customer: replied 3 months ago.
If relay was stuck closed would not fuel pump run all the time even with key off instead it is not running at all. It seems there should be hot wire that is only hot when key on to signal relay to close and pump and other things to operate
Expert:  david craig replied 3 months ago.

you're correct. im am overthinking this. its been flippin 9 days.

Expert:  david craig replied 3 months ago.

check the 30 amp ecu fusible link

Customer: replied 3 months ago.
I'll bet there is a wire from ignition switch to relay that is hot when key is on I need to know what color it is if so.
Expert:  david craig replied 3 months ago.

ok.

Expert:  david craig replied 3 months ago.

its going from ign switch to engine control relay

Expert:  david craig replied 3 months ago.
