cont from this thread.....
I had been having random stalling acts with my 1990 4runner V6 5 speed.
315000km . At first a thougjht it could have been an electrical problem as it would stall and start right back up. But now that it has completely died it seems it is a fuel issue. I brought it to the local garage for repair, but the repair estimate was around $1000. $350 for a pump plus lines fuel filter labour and possibly sending unit. So I have decided I would tackle the repair myself as I have had the fuel tank off the truck before.I was told that the truck would run with a purge.
When I turn on the key I can not hear the fuel pump...but then again I dont recall ever hearing the fuel pump run...probably cause I never tried listening for it.
I was wondering if I could run 12volts directly to the fuel pump connector located under the back seat. To ensure that indeed the fuel pump is the problem before dropping the tank?
I read a couple of post that stated there is a "T" connector on the older 4runners you could short to give power to the fuel pump ..is there a way to do this on this V6 90 4runner?
I see an EFI relay in the fuse box in the engine compartment, is there any other relays that turn on the fuel pump?
Thanks in advance. Cheers Jason
