Hi,

As the subject says, I have a 1990 Ford Bronco II that I bought a couple months ago. It's a 2.9L V6, with a manual transmission and is 4 wheel drive. Recently it has been having trouble starting. It's fine when the engine is still hot or even warm, but after I come out in the morning or after work it takes two or sometimes three tries to get it started. Some times is chugs a little when it starts, but most of the time it just fires right up after I get it to start. I hear the fuel pump prime and everything. I have replaced the fuel filter, plugs and wires, the battery, and tried injector cleaners and what not, but still happens. It Runs amazing when it is running, but it does leak a little oil from the valve covers because I haven't had the money to replace them yet, but I don't think it's enough to have compression issues. Could I just need to replace them or could it be something else?

Inspect and test the engine coolant temperature sensor, idle speed control and throttle position sensor

So. I replaced the ect. And the idle is fine and where it should be when the car is running so I doubt its the tps. I also cleaned out my idle air control valve and it seems to be fine. But it's still having trouble starting. So how and where do I check the idle speed control. Could it be anything else?

Check the fuel pressure if its within specs if not could be the fuel filter and fuel pump to include a fuel pressure leakdown-due to injector/s and fuel pressure regulator leaking-
