Fuel pump not turning on.

did you check for power to the body on the body harness side?? it will be a 2 second signal and then off. it will come back on line when the motor is cranking and starts.

Roy

I'm not sure where to check that.

the body harness where you disconnected the fuel pump. there are several wires there that feed power to the module.

Roy

No power on body harness.

ok. did you check it like I told you?? it only comes on for 2 seconds when the key is turned on. then no power till the motor is cranking and starts.

check for power to the inertia switch. same way 2 seconds when key is turned on.

Roy

Oh, so I need someone to help with that, I'll check and reply as soon as I can.

be back on tomorrow morning

Roy

I checked for power at the pump and inertia switch with someone turning the key for me and didn't get power at all at either of them, had him turn the key while I checked with a multimeter.

ok, you need to go to the relay under the hood. drivers side front, it is a relay with a green connector. make sure you have power on 2 terminals. one is battery power and the other is key on power.

Roy

I can't find any relay with green connectors, my manual doesn't even show one for it, I thought in 94 they put it in the constant control relay module.

if you have that box by the radiator support, then thats where it is. I need to find a diagram for it for you but that unit is a common failure but we need to confirm it before spending the money.

Roy

I actually already bought a new one and replaced it before I asked the question.

you still need power and grounds verified. you did match the numbers???

Roy

I'm not sure what you mean the numbers

there are part numbers on the box. there are several different ones but you cannot interchange them. make sure the part numbers are the same.

Roy

Yes I checked the part numbers were the same.

I'm just at a loss on where to go from here.

you need help. get it to a shop and have them track it down for you.

Roy

I'm sorry I wasted your time I gave the wrong information, the fuse was blown. It's still not working, but it was blown.

its ok. thats headway. now, you have to find out why the fuse blew. it blows for a reason.

Roy

I checked for voltage when the key was turned on and, I'm getting 4.2 volts at the body harness.

no good. has to be at least 12 volts. i am going off for tonight be back tomorrow morning

Roy

Fixed it, the connector comings from body harness to pump was bad.

good job

Roy
