Hey all, So I'm hoping I can get some answers or ideas here. I have a 2000 B4000 that is having starting issues. It will turn and turn and turn but wont start. About a month ago I drove it a short distance and when I got back in it cranked for about 15 seconds before it would start. After that It worked fine until last week. Last week I went to go somewhere and it refused to start. I replaced the fuel filter and it fired right up. The next morning it would not start again. I tried again about 3 hours later and it fired up perfectly but after I turned it off it wouldn't start again. So I replaced the fuel sending unit to include the pump and damper. It fired right up. Next morning wont start again. Tried a couple hours later and after about 20 seconds of cranking it fired up. After I turned it off it wont start. The fuel system is getting power, it has fuel pressure. The neutral safety switch in not popped. I'm pulling my hair out trying to figure out what's going on. I replaced the spark plugs and wires about 4 months ago. New battery about 2 months ago. I'm thinking it might be a crank sensor?.I cant think of anything else. Any ideas???

 

Has it been scanned for fault codes?
