Topic: 22re fuel pump?

[tanman85]

I am new to   and am really excited about my new build!  

I got a 85 runner last week, im in the middle of replacing the fuel pump(the old one was bad).  I got a brand new fuel pump from my uncle for a jeep 4.0 for free so i fugured id give it a shot.  I have it installed.  The truck will start and as long as you pump the gas pedal the truck will stay running and sounds strong.  when you let off the truck dies.  there is a strang noise that comes from the pump but i am un sure of what it could be.  I hear no air noises related to vaccum leak.  i feal like the plugs and injectors are in good shape.  I am stummped!  My dad suggested a timming issue?

Should i get rid of the Jeep pump and just get a toyota pump?

I did a search and could not find anything that helped me!  any help or advice would be awsome!

Thanks guys!

I the jeep pump for fuel injection or carb (less pressure) or throttle body (also usually less pressure) ?

I got a toyota celica pump from an 83, its an inline pump.  Using it on my 85 EFI conversion.

I used an e2000 out of a ford and it works good. Its 95psi i think.

[joey0712]

I just googled that pump.... Looks like it puts out about 40psi max.

[tanman85 [OP]]

What is the PSI on the toyota pump.... i think google hates me!!!  every time i realy need it, it takes a big crap on me!!!

i am not sure on the carb or fuel inj?  i will ask.  did not think of that!

[joey0712]

I read a few threads that said around 40. I havent had any problems running higher psi tho.

well its not working... the jeep pump has to be the week link i just cant figure it.  had a buddy come over and give it a once over he could not see any reason why it should not run.  Gunna give it a shot!

[joey0712]

Why not use a stock pump? I have one i only used for a month or so. Let me know if ya need it.

It only takes about 38lbs of pressure to run toyota efi. If your pump puts out more than that it doesn't matter it has a fuel return that returns it to the tank.


I would get a stock fuel pump or an inline efi pump and get rid of that jeep pump all together

[tanman85 [OP]]

Well... i put the toyota pump in and nothin'   So i am just out of my leage hear!  Guess im gunna have to take it to a Mech.  I dont get it!  Compression is good spark seems to be good no serious vaccum leaks that i can find.     Just want to drive my new toy(no pun intended)

Thanks for the help guys.  Hope its something minor that i am just missing

[joey0712]

make sure the return is free flowing back to the tank.

its sounds to me like a mass air sensor. if air is getting to the intake without going through it or its not working it will give that same problem
