Trouble starting 1990 Acura integra



#1
I have a 1990 Acura integra that has recently been giving me problems starting. I have crank but wont start. I will come back 2 hours later and it will start just fine. When it starts it runs great! No idle issues, no lag, doesn't run rough. It has left me stranded several times now and it's driving me nuts because I can't figure it out. I have recently changed the fuel filter, new plugs, new starter, new battery. I'm thinking it might be the IACV but I'm not sure. Can someone please help!

Do you "prime" the fuel before turning it fully on? I.e. turning the key where all electronics are on but just before you start to crank it and holding it there for about 2-3 seconds. Maybe give that a try

We had that problem. Car would crank forever when the ambient temp was warm or hot. It was a faulty fuel relay switch. Put in a new one and problem solved.
