Hi, I’m new to this forum and could really use some help with my truck. I have a 1989 V6 4x4 4Runner that was working fine until it was stored for the past 3 years. I am unable to start the engine. The engine fires up briefly with starter fluid, but does not stay running due to zero fuel pressure.
I removed and tested the 'Circuit Opening Relay' and verified that there was continuity between terminals STA and E1, B and Fc, and no continuity between terminals B and Fp. I performed this test based on a Toyota manual. I can also hear a clicking noise from this relay when turning the ignition key of the car; I believe this relay is not my problem.
I then directly jumped the fuel pump with the positive charge from my battery and the fuel pump still does not work. I believe the fuel pump is stuck and may work if I clean it. However, I am unable to remove one of the hoses from the 'fuel pump sending unit assembly' which is fastened onto a threaded (and easily bendable) pipe. I am also unable to properly remove the wiring. How do I remove this hose and wiring without damaging the ‘fuel pump sending assembly’?
Any tips in troubleshooting and restoring the fuel pressure on my 4runner is greatly appreciated.
Thanks,
Aris
