2005 ford ranger 4.0l won't start. It acted like it run out of gas. I replaced gas filter and fuel pump. And it didn't help. I replaced the crankshaft position sensor , camshaft position sensor, spark plugs. Coil pack . It has 50 to 60 lb. Of fuel pressure. And has spark at the plugs. I've even tried starting fluid and it wont hit. It shows no codes or pending codes. If I let it set a week or two it will start for about 2 or 3 seconds and die and it wont even hit after that. I'm lost at what to try next. Any help you can give me is welcome.

Did you check compression?

Don't have away to check it. But it doesn't seem any different than it was

You might try looking at the crank position sensor or a cam position sensor.

You can rent a compression check gauge from advance or auto zone for free. Or buy one. I think they are around $20 and very useful for small engines also.

my crank position sensor was loose and it did the same thing, got the plug in a little tighter and it cranked right up
