do you get check engine codes?..have you done a leak down test and compression test to determine mechanical engine health?

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

I reccommend putting WD40 or CRC on the connections to stop them corroding over time. You also want to make sure the Distributor Cap gasket seals well to keep out water. last make sure you don't get the leads mixed up, best to replace them one at a time. cheers

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.
