Hard time starting up

[kyleb617]

My truck seems to have a hardtime cranking over when its cold out or on a hill for some reason, it does crank over on the first try but it seems to lag , any suggestions?

Take your voltmeter out, and check your battery's voltage before you crank it. Batteries are known to crap out whenever the weather changes, normally to cold. If your not getting close to 12 volts, it might be time to replace that mamajama.... Also, make sure youve got a good fuel filter on your truck too. They will collect a boatload of garbage in them, and when your truck sits in the cold, that garbage and gas will start to solidify a bit. Could be giving your truck hell, when your fuel pump is priming it up, until fuel gets flowing from the pump after it starts....

Ford has a tsb for the no start on an incline, it tells you to replace fuel pump. Here it is

Mine is having a similar problem as well, minus the parked on a hill. Any morning where the outside temp is below 50 the truck will start but will idle rough and sporadically die. I did some googling and found it possible to be a bad intake leak at the plenum or something to do with the IAC. Still haven't taken it somewhere to have them troubleshoot (I have no clue how).

Whew! Just how "inclined" is an incline, anyhow? Can't imagine parking on a REALLY steep incline, just a little one affects yanking the selector lever down out of "park" to my disliking.....the fuel tanks (supposedly) of EFI vehicles have a "low-spot" small reservoir designed-in to overcome the incline-problem. Maybe some years/models it was not sufficient?

Just wondering, now, in racing, "fuel cells" are used in which (I think....) the fuel is absorbed in material to prevent gross leakage if tank ruptures. Now Indy-cars have used fuel-injection forever, proly nowadays EFI, so how do they get the fuel sucked out of the absorbent material in the cell, to deliver it to the engine? imp

Its a polyurethane foam cell- it prevents the fuel from being sloshed around. Most boat tanks and race car fuel cells have them. There is a pickup just as a regular tank has normally with a sump built into the tank and fuel lines coming out of the bottom. (hence the ease, of getting low fuel out, and no starvation).
Some have them come out of the top, just with a sump for the pickup in the base...

It doesnt nec absorb the fuel, it just prevents it from sloshing around.

Good info, appreciated! FWIW, the Ford Pinto spectacle with rear-end collision-caused fires way back when, finally revealed the FILL-TUBE was secured to tank down low, thus allowing longer fill-path, less "burping-back" while filling, a good idea, helpful in use, BUT, collision tended to SHEAR OFF the fill pipe, which allowed quick drainage of lots of fuel, then fire.

Critics blamed LOCATION of tank in front of rear bumber, but looking at small cars then, many had tank located exactly the same. Pinto became the scapegoat, unfortunately. imp
