Start up frustration

Hey Guys

This was fun 4 days ago when I started this but my patients is wearing thin. Replaced the primer pump, pumped until I got all of the air bubbles out of the loosened hollow screw. Cracked the injectors on the #1. Turned the key and came as close as it has come so far to starting up. I had someone else turn the key while I bled the valves but still no go. It almost starts but won't. One thing I am wondering is 1. How do I know if there is fuel coming from the fuel tank. 2. should there be any air bubble in the see thru filter. Thanks again guys. I am the closest I have been yet.

You can loosen or remove the spin on filter and crank too see if you are getting fuel from the tank. It is normal to have a marble sized bubbler in the pre-filter. Is your glow plug system working? How is the engine's compression?

1. If there is fuel moving through the clear filter, it must be coming from the tank.

2. Bubble is normal. Bigger than a marble is ok too.

keep it all in the same original thread or the advice is going to get repeated and confusing.
Have you checked the resistance of the plugs yet?

Are you thinking that new plugs would somehow be bad?And the fuel in the filter I put in there because the primer pump was taking forever to fill it up, so i funneled it in. The primer pump only seems to be pushing fuel toward the spin on, but not from the secondary.

Possibly. The number one reason for hard starts on these engines is malfunctioning glow plugs. Before I spent much time chasing down other problems, I'd confirm voltage at the plugs and proper resistance. You've confirmed voltage, albeit somewhat low, but not proper resistance. It's a simple 2 minute test that would exclude bad plugs.

OK Guys

I have somewhat of a success. I got.9 ohms from the glow plugs across the board.But I put the car in neutral and it started up,for about 6 seconds,and then it died. But when I tried to crank again it didn't seem to be firing at all. Whats the deal? I think I am close.
