I have a 1995 Tacoma 2WD which will not start hot in the heat (meaning if its below 50 it will start). Toyota charged me over a thousand dollars and said there was no problem. The only truth to that is they didn't fix anything!
A master Toyota mechanic who used to work for Toyota looked at it. He didn't believe there was a problem at first either (I had to convince him by running it hot then letting him try to start it). The computer does not indicate any problem. He did troubleshoot it down to the fuel injectors getting only a half volt of power from a hot start so the problem is no fuel, but he could not fix it as he said the routine he needed to know to trace the problem further was the "start" routine and Toyota won't release it (he has the run routine for the computer but once it is started, it has no trouble running). He said he could end up swapping parts and charging me over $5K and not fix the problem. I certainly know Toyota would do that.
I did call Toyota USA olny to be given a polite (or not so polite) shove off. My truck has done a great job for me and I can't complain about the initial manufacturing of the vehicle, but I have found the service at Toyota dealers to be extremely sub par and the concern Toyota USA (the supposed mother company of them) has demonstrates why the service is so sub par.
Is there any help out there?
