Replaced tps, iac, map sensor, crank position sensor, and coolent tremp sensor. Car runs much better but still starts hard.
So figure this one out...
Car starts hard cold. However if its hot it only starts hard if you let it sit for more then a minute. Run into a gas station to grab smokes, come back out and it fires right up perfect every time. but let it sit and it cranks forever. My insticts thought maybe a fpr or fuel pump, but after sitting for 10 minutes, there was still plenty of fuel pressure.
Ive done my share of diagnostics, but im lost on this one......
