460 efi questions
I'm sure there are the answers in existing posts but I wanted more input before I started throwing all kinds of parts at my truck. I have a 91 f250 efi.
My symptoms are,
1)hard starting when warm, I've found that it could be the check valve in the fuel system, ICM and distributor bushings.
2)won't idle high when cold and stinks, that could be coolant temp sensor, o2 sensor
3) when I run off of the front tank the return line goes into the back tank, check valve in fuel system,
So I realize some of these solutions overlap, but I want to know the details I'm replacing each one instead of just buying parts at it till it's fixed. I looked up the parts for the EGR valve i saw that there was a valve and a position pressure part, i didn't know which one needs to be replaced. I did a scan and the only code I got was 32 for the EGR position pressure. I'm just thirsty for all the info I can get.
