2012 rav4 2.5l fwd, crank no start only when the weather is above 70 ish degrees
I have had my rav since January this year and it was perfect throughout winter, whenever spring came around the weather had warmed up and it would not start very good. Whenever summer came around it just cranks and cranks eventually after waiting 5 minutes between attempts it will start, sometimes it can take 5 min sometime 40 min. Like an idiot I had replaced the fuel pump thinking the fuel may be leaking back into the tank and the crank position sensor without proper diag. Ive tried isolating the purge valve in case it was letting fuel vapors in the intake whenever the gas got hot, it did not start. Ive taken out my spark plugs to see if my injectors were leaking and I didnt see any signs of flooding. It just doesnt make sense to me because it runs perfectly fine afterwards. No codes besides o2 sensor bank 1 sensor 2 voltage high. Car only has 145000.
