very hard start after sitting a day or overnight
I cant seem to figure this one out...it did this before I replaced the fuel pump a few weeks ago (delphi oem pump). If the truck sits overnight or I let it sit a full day...it starts very rough...like holding the key forward and starter dragging. I just replaced the IAC because it kept jumping rpms at start up and that seemed to fixed the rpm problem
What should I check. ..battery seems fine and is just a year old....altenator is 2 years old but a remand and I just cleaned the throttle body when the iac was put in.
Also the truck starts perfectly fine after its been started in the last 6 or minus hours
Any suggestions? Thank you!

Plug and wires and cap and rotot were done 30k ago....I have 165k on it and im not 100% sure if its the originial distributor or not...Ill have to look at the bills when I got the tune up and see if that was replaced. And yes the coolant temp sensor is connected and working

A fuel pressure and leak down test should be done. Sounds like you have a leak in the system draining off pressure.

what are the proper procedures for the pressure and leakdown test, im kinda a noob when it comes to this, any videos showing how to do this properly?

did the fuel line need to be bled after the fuel pump was installed?

UPDATE: took my friends advice and did the easy free thing before i spent money on a pressure tester, got my battery tested. it failed in cranking amps, the guy was suprised i was able to start my vehicle with what it registered. got a brand new one under warranty. gonna see if this was the reason why it was starting hard
