Major trouble

[travisdj]

I hate problems like this.
Are you still getting th IP replaced from the seller?

Hop eyou get it going, getting close to getting mine going as well, been sitting for 13 months now

I replaced the fuel filter on Saturday, and we are going to mess with it today. I really hope to have it going this week. It will save me a ton on fuel and I just love driving it even though the a/c doesn't work. I may end up having to get a new one from the seller. It just doesn't seem to be sucking enough fuel. Every time we take the return line off the filter it isn't full of fuel. I don't know what the deal is.

Anyone know how to bleed these things. I don't think there are any leaks anymore since we replaced the leaky seal. I am just stumped. I'll keep at it though.

One thing you can try just to make sure you dont have a problem in your fuel system before the IP is to get a good clean container and run a line from it to your IP thus bypassing the OE fuel system.
Like a 1 gal gas can or even a 32oz Gatorade bottle works.

just to see if you have a problem there.

Yeah that will be the next step after bleeding the system. I think we are getting closer to this bad boy runnin.

Ok we got it cranked now. It starts up but quickly runs away. I know I saw a post on this subject but I can't find it now. Can anyone help?

Turn down your max fuel screw.

Roger that. There is a bunch of air in the return line and the filter doesn't stay full. My buddy said it is cavitating in the pump. We pressurized the fuel tank and got a little better with it cranking up. We can get it to run, but then idle gets really bad and it dies. I may have to video it all and post it so you can see. That may make things easier.

this is where having a lift pump would be great... i would first try possibly by-passing the fuel filter just to make sure that isn't the culprit (sometimes the fuel pre-heater can leak...)

For those of you wondering how you time the pump 180 degrees out:

There are 2 styles of pulleys, some have 2 holes in them and there is no way to tell which one is the proper one to use to line it up with the pump locking tool. They are both identical. The only way to actually tell is to remove the pulley and the key should be at about the 11 o'clock position at TDC.

As far as your problem with the pump, hook it up to a bottle and run it off of that and see what happens. It sounds like a fuel delivery problem, most likely from your lines etc. Did you prefill the fuel filter when you changed it?

Until you can verify the timing with a gauge you are just shooting in the dark, although it does sound like there is more going on here then just bad timing.

You may want to just let it idle for 5-10 minutes to see if that clears the lines

Ok, so I timed the pump today. It was WAY off. I got it to idle for a few minutes but it would not respond to throttle. I guess there may be air in the lines. Any ideas? I appreciate everyone's help. You guys rock.

[jimfoo]

Maybe the throttle arm isn't on the shaft in the right position.

That is the next thing I am going to mess with. What else should I look at? Air in the fuel system? Thanks for the help guys.

Ok, so now almost everything is worked out. The big problem now is that fuel cannot get from the fuel tank to the injection pump. Fuel can get to the expansion tank just fine, but cannot get to the fuel filter from there. Is there something in the expansion tank that causes this hangup or do I need all new fuel lines? Where is a good place to get fuel lines? I'm not looking at going with one of the pricey viton line kits yet.

[burn_your_money]

Where is this expansion tank you speak of?

[travisdj]

Where is this expansion tank you speak of?

Under the back seat mounted on the bottom of the car. I believe it's an expansion tank. Fuel gets to it fine, but fuel won't go from it to the filter and on to the pump.

The water trap (you are calling it the expansion tank??) is often a source of an air leak into the fuel system. The cheap plastic construction breaks down in cracks so that the fuel is getting air as the pump attempts to draw from the the fuel tank beyond.  Bypass it with some neoprene hose, hose barbs and clamps. You will probably find that this is your problem zone. Besides, with the generally good quality of fuel here as well as the throw away fuel filter under the hood, you probably don't need the separator anyway.
