Cold start injector
95% of the time thats what it is on fords at least. haha.
I know its not the pump since I already replaced it.
The other 5% it's something else on a ford = 100% broken one way or another. DO, keep an open mind here , DON'T get caught with the mentality that "because it's new it can't be the problem". We have a saying in this industry,"Just cuz it's new doesn't mean it's any good". A new one can fail as well as an old one It's still the same piece. This is why we have warranties.
I know all to well how that goes.....guess I should clarify a little about myself. I have been working as a technician for ford going on 8years now. I started chaning oil, went to fomoco training program and now have my ford senior master and ase master certs. I have done alot of gas performance and now working on strickly diesels currently. so yeah I have a little automotive knowledege. I just havent had any toyota experence or way old EFI experence. I am a little young I guess, I mostly deal with EEC V and newer vehicles at work. I know I can fix it just need a little direction and known concerns first. That FSM is helping alot too, I am reading it now.
Never took it as an insult, just wanted to clarify what my level of knowledge was to save time. you would have no idea what my skill level or thought process was. no need to go over the simple little things that are common sense. sure some people might not know but I know how talking "tech to tech" is compared to someone that might not have any type of experence. no need to "dumb" it up for me.
The whole pump not cycling on KOEO is weird to me.
if that seems to be working i am going to yank the upper intake. i have a feeling it might be so carboned up its causing injectors be sluggish for lack of better theory. with talking with some of the old timers around the shop this seemed to be a issue on the early fuel injection engines.
well the thermo switch tests out ok according to the manual. however they only have to test resistance and I have seen sensors test fine like that but still not work so who knows. I am going to test compression tomorrow which I need to do anyway to determine engine condition. If I get time I might pull apart the intake a clean it.
very good question, something I did not think about....I have not drained it, however it does have decent coolant leak. I keep it full but I bought it knowing this. It also had this cranking problem as well. I am not sure if the PO filled it correctly or not. Its a freeze plug int he back of the motor so I am waiting til I pull the trans do to the doubler and do everything at once. it should happen soon.is there a vent plug or something I need to pull when filling?
