Sprout / pip / knock sensor
It came to my knowledge that the sprout unplugged allows you to time and where to un plugged shows based timing before auto advancement is it possible to run with it unplugged and start all the time with out it with no problem I ask because you can't find old knok sensors have an 98 F 150 5.0 EFI enjion coad n just curious

I'm sorry, but I had some difficulty interpreting what you wrote.
Pulling the spout prevents the EEC from automatically adjusting the ignition timing. It does this based on various operating parameters to attempt to run the engine at its most optimal capability. Why would you want to disable that?

Knock sensor has nothing to do with starting so I don't see how this is related.
No you don't, the last year the 5.0 was installed in an F150 was '96 so if your truck is a '98 it's got a 4.6L.

Sounds like you need to check the timing. Get your timing light attached, loosen the distributor clamp bolt and start the engine and let it settle into a steady idle(good idea to get it warmed up a little beforehand). Now find the spout plug in the distributor wiring harness.. a little grey plug, and pull it out to disable computer advance. Then turn the distributor until you see 10deg BTDC on the crank balancer, snug down the distributor, put the spout plug back in, and disconnect the timing light. Now the timing is set where it's supposed to be so you shouldn't have any knocking, but take it for a test drive to see and report back.

Get a vacuum gauge, a T-fitting for one of the vacuum lines, and a short section of hose, and install it between the line and its fitting. You should be able to do this without destroying anything.
