Toyota Repair/hard start when hot


1985 4runner 22rec. starts fine when cold in the morning after setting out in the heat all day it takes at least 35 seconds to 1 min some times longer before it will start i've all ready fried a starter. could it be Circuit opening relay

This may be due to a malfunction of the cold start injector or the injector time switch or fuel pressure regulator, before replacing anyhting I would check fuel pressure when the problem is happening, a pressure gauge can be connected to the cold start injector fitting
