Question about 1984 Toyota Pickup Deluxe

2 Answers

I put 2 napa (carter oe replacement) fuel pumps and both have 9 psi. The problem is that the rebuilt carb i also put on does not shut off the needle valve and so the carb floods and the engine smokes then stalls. Carb shop that did the rebuild tested carb on a motor in thier shop (off my truck). What is the spec value of the oem fuel pump? I believe the pump may be forcing fuel past the needle valve at idle especially. This is 1984 4wd 22r mechanical pump

Hi, the pump cannot overpower the float. Either the carb was not assembled properly, or the needle or seat is damaged. What model is your carb?

Have the carb rechecked that the float is correctly set and valve is not worn or debris and fuel pressure between 7 to 10 lbs

Saw your post on another thread. I have the same truck. The fuel filter is located on the rail just below the passenger door. Its an easy one to remove,...couple bolts, but access to it is a pain.

SOURCE: 1986 toyota pickup starts wont stay running

It seems there is some kind of air entering the carburator where its not required to do so or the idling soleniod switch is malfunctioning, thus not allowing the air to enter for the engine to idle .
Also recheck the vaccum pipes if they are correctly refitted per the schematics under the hood.More over remove the idling switch and blow some air to the hole probabley theres some kind of obstruction over there .

Good Luck.

Knight.

How do I check the fuel pressure on a 2000 model mazda millenia with a 2.3 engine in it


Hi.

You connect a fuel pressure gauge like this to the pressure rail. Pressure in this car must be between 35 and 45 psi. If pressure is too low look for kinked fuel lines and eventually replace the pump. If the pressure drops down more than 10 psi in five minutes or if the pressure is considerably higher than that replace the fuel pressure regulator. Below the parts that may need testing:

1. Fuel tank
2. Shut-off valve
3. Non-return valve
4. Fuel pump
5. Fuel pump (Transfer)
6. Fuel filter (High-pressure)
7. Injector
8. Pressure regulator
9. PRC solenoid valve
10. Fuel pump relay
11. Fuel pump resistor and relay (KJ model)

1954 CORVETTE,3 CARTER YH CARBS, SET FLOATS @ 3/8 '' with a 2'' drop to bottom of float. Engine runs fine, but carbs leak gas freely upon shutting engine ''off''. Why? and how can this be fixed?


Check the needle and seat in the carbs, sounds as if the needle is not seating allowing gas to flow till pressure in the lines drop. Since bowl is full the gas will force its way out any place it can. Usually a gasket. Good luck!! Hope I gave you an idea of where to look.

The 2.5 L engine is the Pontiac Iron Duke sourced from GM since it was still AMC. They came with Rochester carbs, while Ford used Holley 2 brls on their 4 cyl engines and Chrysler used Carter carbs. You might have the wrong carb and the throttle plates are sticking on the intake manifold. You can try using a carb adapter/spacer. If you drive off road I would suggest buying a TBI throttle body injection system from a junkyard, and pick up a electirc fuel pump. Either new from a speed shop or used from a newer Jeep with a 2.5 L TBI engine, you'll need the computer, harness, relay, sending unit and lines as well. But you can pick up everything at a pick your part yard for cheap (some yards have all you can carry in your hands for $50 days).

Troubleshooting fuel system for 1975 jeep cj5


Fuel pumps just supply fuel to the carb. Either they work or don't work. I would make sure that the mixture screws on the carb are set properly. Turn the screws in to lean out the mixture, do one at a time.
You want to turn the screws in to the point where the jeep will start to idle rough and then back out a 1/2 turn. Check your timing also. If the jeep has alot of miles on it, the timing chain will stretch and it's possible that you cannot get the correct timing.

Hi there 1960 series 2 land rover. Problem - idles ok on flat but dies on the slope/hill. Have put new parts in solex carburettor (Float etc). Is it the fuel pump?


Speaking solely from experience with working on and tuning different types of carburetors,mostly racing type cars,a carb engine that dies on a slope is starving for fuel,obviously,and more often than not it's either the float level and drop,or needles and seats.It is critical to measure and set the drop of the floats to prevent fuel starvation,as well as the maximum level allowed by the floats,to prevent flooding out the top.Needles and seats regulate the fuel coming into the carb based on the float level,so they are tightly intertwined with one another.Later versions of carburetors have high flow,and/or spring loaded needles and seats for extreme 4x4 climbing,so that starvation isn't an issue.Check fuel pressure from the pump,as well as volume,Volume is as important as pressure.You can measure volume easily with an empty jug and a helper to crank the engine over while you hold the fuel line into the jug,and watch how much fuel it's pumping.Easy and cheap check,plus you can watch what kind of pressure the pump is developing.6 psi is about the standard for carbs at the inlet.Racing engines can run 7-8 psi fuel pressure.Good luck.

you may want to check the fuel filter by taking it off and try blowing through it. if you have blowen through a straw and the filter is harder then that replace it. it is running for 10 seconds because its using the fuel in the carb and then it shuts off right. its not to much pressure but could also be a stuck needle valve in the carb. you should make sure you have fuel going to it first. take the line off and stick it in a bucket and turn on the pump you should get fuel coming out thats good. dont need to run it for more then a couple seconds if nothing comes out the filter is clogged the pickup screen is clogged or the line is clogged. good luck hope this helps
