Well first of all im quite new here but ive seen some good advice on different people asking questions about there fuel pump issues.
I own a 1993 Landcruiser (FZJ80) Petrol. I have a crank but no start issue. I have been trying to diagnose the issue myself with no hope. The information I have currently may be helpful to a few of you who understand a bit more about the electrical side of a car then me.
First of all I am getting no fuel to my fuel rail while car is in the ON position and also while cranking in the START position. I went out and brought a new fuel pump with no hope. From here I decided that I wasnt gonna go out and spend money on everything fuel issues before I knew what it was. I went back to the fuel pump which is under the rear passenger seats. I noticed that there was no power going to the fuel pump at all, But take note there is 12V going to the fuel gauge showing how much fuel I have in the tank. This got me thinking maybe it was a Fuel pump relay issue or a Circuit opening relay issue. I felt my Circuit opening relay click on every time I turned the car into the ON position which that seems all fine. I couldnt do the fuel pump relay by myself but I did have a multi meter to test for ohms which it was about 80 ohms and I read somewhere between 50-120 ohms was ok for those coils.
After all of that I turned my attention to the fuel pump resistor (Which I didnt know these cars had one but found it reading about fuel pump wiring). I tested the ohms on this too which it was recommended for 0.73 ohms and I got around 0.79 ohms which I thought ok that seems good enough. Now im a bit confused on what it could be.
I had a little look online and found out I was able to give the fuel pump 12V from the diagnoses by jumping B+ and FP, In my surprise this worked and the car was starting. But I dont wanna drive on that. On the same forum I read they said this bypass the fuel pump relay and resistor. (Im not sure about the Opening circuit relay).
Now I am currently stuck on what to do next? Any help would be nice!
(I understand this is a bit long but im just trying to give all the information I have about this issue to someone with a bit more knowledge then me to help me out)
