Air intrusion on 1990 7.3L f350 with banks turbo
I will try pushing the schrader tmw am. I can say that when I had the clear tube hooked up between #1 injector and fuel pump housing, the top of the tube would get air bubbles after it sits. But I'm unsure where they come from. As I understand it, if there is air in the low pressure line...- danda

Air intrusion on 1990 7.3L f350 with banks turbo
Ok, I believe I've eliminated the "bad glow plugs" theory. I made a little test light using an old tail-light bulb of unknown resistance with leads soldered to it. I then checked it against 2 known good beru plugs and 2 old questionable autolite plugs, one with an expanded tip. The expanded...- danda

oh, also I checked that voltage between battery positive and glow plugs body (and other points on the motor) is the same as battery voltage between posts, indicating the ground is good.- danda

cranking speed is fast and I've been keeping the batts charged. no issue there. I was curious about total amperage being drawn when the plugs are active because I saw elsewhere on the forum that it should be in the range of 200-230 amps, so about 25-28 amps per plug. I stuck my clamp meter...- danda

Air intrusion on 1990 7.3L f350 with banks turbo
yeah, your theory kinda clicked with me overnight. I wasn't really thinking along those lines before because I (perhaps wrongly) believed glow plugs to be working. Ok so this morning I went to plugin block heater and discovered that the wire was (a) super brittle in places and (b) severed. I...- danda

not sure if the heater works. I will try it and see. Anyway it has been warm days here, and my other diesel truck fires up no problem.- danda

Air intrusion on 1990 7.3L f350 with banks turbo
thx for reply. Glow plugs were all changed a few years back and have approx 80 miles on them. That said, I suspect at least one is bad because I get some extra clicking from relay after the "Wait to start" light turns off. Yesterday I found one with the wire disconnected and reconnected it...- danda

Air intrusion on 1990 7.3L f350 with banks turbo
Ok guys, so I've got the classic hard start due to air intrusion. I bought this truck used in 2000 with 113k miles on it and have use it very infrequently, so mostly it has sat. A few years back it developed the hard start symptoms and I replaced the glow plugs and return lines, which did not...- danda
