The last few mornings it's been hard to start the Camaro. Only in the mornings though after the car has been sitting. I'm wondering if it's the fuel pump or a temperature sensor?

Last month I replaced old rust fuel line with new metal line and changed the fuel filter too. I don't smell any fuel so I don't believe there's a leak anywhere. Any help would be appreciated!

 

Fuel pressure test while the car is hard to start would tell if its the pump. Temperture would not relly come into play until the car was in closed loop. Could be a crank sensor also.

 

Thanks for the advice. I'll do a fuel pressure check. Crank case sensors aren't cheap either though. But the fuel pump is a paint to change in these cars.

 

Well, I pulled a stupid! The crankcase ventillation tube wasn't connected to the engine. I took off the intake tube to clean it a few days ago and didn't think to check if the vent tube was in. It started easier this morning!
