Ignition
Hi, my 88 supra takes abnormally long to start when it is cold. Is it because of the fuel pump or am I just getting a weak spark? Also when the engine starts to start it studders then finally gets going. Anyone know any tips or had this happen to them? Thanks.

Check your cold start injector, make sure the plug is connected.
or Cold Start Injector Time Switch might be out of specs, again check the connection. FI-77 and FI-112 show you how to check them. http://www.turboninjas.com/mk3supra/...-EFISystem.pdf Those are the two easiest things to check for a cold start problem.

I don't think its your problem, but read this to eliminate it as a possible.
http://www.toyota-supra.info/forums/...ead.php?t=4657 note... Also, the switch is heat/cold controlled. If the temp outside is more than about 65* (maybe 55*) it won't allow the injector to come on, to prevent flooding. Also, even in a snow storm, after 12 seconds of cranking time, the switch will stop supplying current to the injector. (prevent flooding)
