fuel pump

Quick question here. Would a bad connection at the fuel pump cause a weak signal, which in turn would cause it to think its running lean and cause a High idle?

the fuel pump is just 12v on or off...it doesnt recieve or send any "signals".

so no...youve got other issues.

Signal was probably a bad choice of wording.
But with a bad connection, although good enough to still run and drive, would the pump be weak? I've heard of weak pumps being the culprit of a high idle situation although rarely but i've seen it on here before. The reason I asked is because my connector at the fuel pump deteriorated away to nothing and the wires were just hanging there, but somehow still worked. So I went ahead and took each wire and crimped it to the nipples on top of the fuel pump and filled that area with silicon. Well I seen a ranger with no bed at the junk yard the other day and went over and unplugged the connector and snipped the wires off about 10 inches back so I can splice it together. At the least, I'll have a good connection whether it matters or not.

if the pump was so weak that it was causing the truck to run lean, you'd likely trip a CEL.

i think your on the right track with replacing the plug, but i still dont think thats your problem. but who knows

Well put it this way at least it wont do it no harm putting the new plug on. Its a god darn vacuum leak and I'm gonna have to go searching.
