My 99 toyota 4runner had issues of starting up. After a few cranks of not starting boom it start up. After a week of this problem happening maybe 2 or 3 times during the week, I decied to replace my fuel pump and strainer. After done that it started up the first time and I took it for a spin for about 10 miles nothing happing but after I turned it off after coming back. I decided to take it for another run..everything was smooth so I decided to open her up and full throtle it. Then coming to a stop sign slowing down it died out then I pulled over put it in park and started it right back up then after coming home I checked out the fuel pump wire harness the power wire was really hot. Is that normal?? After turning it off for a few mins I started my truck back up after running for a few mins it died out once again? Can anyone help me out ? This is my family transportation so I need it reliable once again.

Thank you!

 

anyone?!

 

Don't know about the fuel pump, but have you tried cleaning the throttle body and idle air control valve (look up how to clean IAC). My IAC was clogged and my 4runner would randomly die driving up to a stop light.

 

I changed my IAC about a year ago. I remebered geting a engine check light also with my IAC and changed it and cleared the code out. With the problem IM geting now it isnt throwing my a engine check light or code. could it be a main fuel pump relay failing on me?

any help would be great thanks!

 

plus is it normal for the power wire geting really hot on the fuel pump harness?

 

come on guys i really need your help. the power wire on the fuelpump wireharness is extremly hot and where are those relays for fuel?? HELP!!

 

bump.....

 

Sorry man, I wish I could help you. I know how frustrating things like this can be. <aybe someone will chime in later and give you some suggestions.

 

haha thanks

come on you toyota gurus. help me out.

 

did you replace the fuel filter? No point in having a new pump when the filter is making it work too hard it fails again. How is the rest of the tune up? plugs? pcv and air filter?

 

IM doubting if it was even the fuelpump now. could I have hooked up the fuel lines wrong when I droped the tank there were 3 lines, one of them had a fiting and a connector and the other 2 were regular lines with clamps on them. I havent changed the fuel filter but will do that.

Does anyone know about that hot wire? and the dieing out after full throtle and coming to a complete stop. thanks everyone for there input.
