cold start time injector switch, first start of the morning is a rough one Options

[brianforster]

so art and i were talking and we both seem to have the same problem, the first start of a morning when its not really cold or not really hot and the car seems to bog out, maybe requiring 2 or 3 cranks and then from then on during the day it fires up first time.

has anyone else ever experienced this with their swap?

art thinks (and i agree) that it is the cold start time injector switch, but that is an 80 dollar replacement from toyota, so if anyone else has had this problem or has any other ideas, id like to hear them.

find a car that has the same switch in the junkyard, and test your theory!
i picked up like 4 coolant temp switches from my local junker off diffrent 'yotas for my cousins deuce a couple weeks ago...5$ covered it

[brianforster]

so id take off all the sensors on the thermostat housing in the junk yard? lol

unless someone knows a noticeable difference between that, the coolant temp gauge, and the coolant temp ecu switches

problem with that is that the 3s has different resistance numbers then a normal 5sfe youll find in a yard.

[presure2]

according to the epc, and partznet, the 5s one, and the 3s one of the same year should be interchangeable.

hmm good stuff. ill have to try to find one off a 5sfe and try it out.

why are the last 2 digits different in the part numbers?

the first one is for a st182 and the second is for the at180 (ST)

[brianforster]

what about a 7afe one?

I have the same problem

[brianforster]

can someone compare 7afe part numbers?

[presure2]

no its not the same.

x2, but only when its like below 35 degrees

so it seems i fixed the problem on my car.

i managed to get another sensor from a junk yard. my original sensor is #89462-20020, with a white harness plug (on the sensor itself, the wiring harness plug is brown) and it says its its a 7k resistor. the new one i found is part number 89462-20030 with a brown plug and it says its a 4k resistor. it came out of some random toyota, but the wiring harness plugs right in. i installed it and the car starts right up on 1st crank. ill have to give it a few more days of cold/hot starts to make sure the lower resistor dosnt cause a problem, but so far it seems to work well. ill report back again in a few days if anything has changed.

the funny thing is, when i took out my old sensor and tested it to the bgb specs, it seems to be totally within spec! maybe the contacts were not making a good connection or something else was going on, because it seems that is was in fact the cause of the problem.

awesome art, another common swap problem nailed shut (well, almost)

yah this is a common problem and Sometimes I sit in the morning... its got to be early when its cold but not too cold... it boggs acts really goofy. Went to check it and the afm was hanging by a thread.... but I figured thats why it was doing that... sometimes it takes 2-3x to crank afterward.. its very weird... But it always cranks its not something I would want to pay 80 dollars for if it only happens once a week.

if its just a starting problem, then its the sensor i just replaced.... BUT, if it runs really bad once its already started up and the problem goes away once the motor comes up to temp, then its the green temp sensor right next to the one for the cold stars.

also, you afm needs to be secure and air tight, or the car will never run right.

I have this problem but only after it rains really good and the car sits over night. What happens is it will fire up but it won't come up to the right idle it will only idle to about 300 or 400 until I give it gas then the idle will jump up to 1700 or so until it starts to warm up. I think my temp sensor is starting to go.

yeah thats the cold start injector time switch problem. over time it will get worse and worse.

Man this is so weird, it almost seems as though its happening to everyone at once. This morning it took 3 turns to get it on, finally when i got it on it sputtered and turned off. this happend 3 times. If you have could you post a pic of the sensor? maybe mine is going bad as well. Like you said it gets worse overtime.

[chacha]

maybe this can help me too...what does it look like and where it is located...my idle is very low...doesn't start high at all in the mornings...i need to floor it and keep it gased for the car to sound normal...or else it bogs like it's going to die, i want a strong normal start...just ONE CLICK!
If you can take pictures and tell us what to do and how to do fix it...i would greatly appreciate...

ANY SUGGESTIONS FOR Speedometer fixing? I ran a Cops' Speedometer Checker and i was running at 70MPH and was around 4.5PRM...but accordingly to the cops' device, it measured me going @60MPH only...any help? How do i get this straighten out?
