85 4Runner Fuel Issue....
Heres the deal Bob Roggy at Roggy Ent. has finished my coil conversion in the rear of the 4Runner the installation is tits to say the least. As a result I have had to install a remote 22 Gal. fuel cell from Summit and a fuel pump on the frame rail. Orginally I hooked up the wires from the new feul pump to the existing factory wires which travel through the factory harness (Excluding the sender wires for the fuel level in dash gauge). On first attempt to start the truck it ran for apprx. 2 sec.......then all it would do is key start and keep turning over.
I checked fuses and came to find I had popped a 10a under the dash I raplaced that fuse and tried again.....same results except I didnt blow the fuse. Since this first incident there is no power to the factory wires????
To date I have installed a remote wire for the fuel pump, along with a 15a fuse to a dash mounted toggle. Hoping this would solve the problem I attepted another start of the motor. Currently it starts and runs for about 1 sec. and then dies???? I am at lose as to why this is happening. Another note is that the fuel pump keeps on running with fuel pressure at the EFI on the engine....I checked the check valve on the EFI unit on the motor to make sure its delivering fuel....it is .
Everything is grounded, the factory charcoal canister line is open from the engine compartment (which shouldnt matter?) The new pump is running at 97 PSI (I was told a factory Toyota fuel pump for EFI motors run at 90PSI.
My next thoughts for tonights troubleshooting are to look at the factory wiring and trace it ...................is there another fuel pump relay I could have blow in line?? If this wiring is good hook it back up to the stock wiring and see what happens.
Questions:
Do I have the right PSI Pump?
Does the factory Toy Fuel pump have an internal on and off switch for pressure?
Do I have to regulate this pressure?
Does the tank have to be grounded?
Any information would be helpful.....UGET IT
This is UGET IT over at Lance house drinking Cabo Wabo Tequlia....LOL
