i have a 1990 4runner 6cyl that wont start. it was running jus fine, went to the store, then didnt wanna start. it turns over, but doesnt start. it is definitely gettin enough juice from the battery. i towed it back home and disconnected the air box from the throttle body. it looks pretty dirty. i tried starting it without the air box and it almost starts. i tried giving it gas, and there was a small explosion (pop) from the throttle body. any ideas? thanks in advance

 

i cleaned the throttle body and connected everything back up. it started fine all day yesterday. i would even turn it off then back on a few times and it would start jus fine. now it doesnt start again. any ideas ? im thinking the fuel pump? any help at all is greatly needed and appreciated.

 

i replaced the fuel pump and it was working fine. the only problem now was that rpms wont go above 3000. i changed the distributor cap and rotor, and now it only starts for a second and then turns off. if i disconnect the volume air flow meter, it stays on for like a second longer.
any ideas?
anyone at all?
any thoughts are appreciated

forgot to mention. I also pried open the vloume air flow meter and if i hold the little door open, the runner stays on. maybe a bad vaf?

please someone anyone help!!!

 

got another afm and it starts now but it still wont go above 3000 rpms.
help please

 

I just became the proud owner of a 1992 pickup that may have the same issue as you. I'm wondering if you have solved your 4runners problem? I would like to fix this myself and would greatly appreciate some advice.

 

i changed the fuel pump again and now she runs like a champ. i guess i got a faulty one the first time

 

now im having the same problem as the beginning. it doesnt start at all.
havent had much luck receiving help here, but im still hopeful
does anyone have any ideas at all?

 

If so, what did it? I think I'm having the same problem. Thanks

 

Something to try:

it ended up being the fuel pump. had to replace it like 3 times before i finally got a good one. it drove me insane for a while. turned out it had nothing to do with the sensor. i jus kept getting defective pumps... hope that helps
