Hey guys. So I brought this here because I've never not gotten good info. My girlfriend just bought a 2000 Acura TL from a family friend with 189k miles on it. It had a timing belt done at 169k but it has an unbelievably bad time cranking over. It takes about 5 seconds if not more to turn over. I have no idea what is causing it as I ran fuel system cleaner through it today along with checking the air intake and cleaning the intake system, doing upstream oxygen sensor change and spark plugs.
Any ideas of help is much appreciated guys, this has been driving me crazy and the car does fine starting up after its been running for a while but if you leave it for 5 minutes or more its back to 5< seconds or more cranking time. Also the fuel filter can't be replaced, just the whole pump
