Fuel filter change, won't start..
Fuel filter change, won't start..
I loosened the hard lines to the injectors and cranked it. The front four (1,2,4,5) leaked fuel. The rear (3) didn't leak at all. I'm beginning to think I shouldn't have purchased this car, even as cheap as it was.
What's going on here? I tried cranking it for 20-30 seconds a couple times with a few minute break in between to let the starter cool down and still nothing. I've given up for the moment.

I purged the motor today and then changed the inline, and screw on filter on my 617. Then I found out my hand primer wasn't functioning, so I figured I'd just be trying to turn it over for a while. No workie...

I sealed the hand primer and bled the last line and the car started almost immediately, but after a second or two of running it died. This happened about 7 times. I'm holding off until morning for further experimentation. I'm looking for any other ideas as to what would be causing this. I also bled the other lines but to no better result.

. Cranking whilst in drive. I agree changing a filter always leads to air in lines and a whole lot of cranking.I've often made the mistake of swapping a dirty filter on a cold day.
Always plan to have a nice warm motor before fucking around with filters.

But if you have fuel coming from that bleed valve without any air I would think it would be in the hard lines. Crack em and try bleeding again?????
Manual says if it won't stay running its air in the system. Have you checked your pump area again? Might have to upgrade the pump to avoid letting air.
Those are my ramblings and two bits. Back to the beers.
Good luck and don't give up
I recently changed both filters on my 83 and had a similar situation happen. Once I bled the air out at the plug on top of the big filter I kept cranking - fearing I would have to open the hard lines. Then just as I thought it was time to crack them it fired up and sputtered till I gave it throttled up and then it was all good.

(01-27-2013, 01:06 AM)rmd2k1 When you change the spin on filter fill it with fuel. Makes things much easier
Yeah. it was filled 2/3 of the way up before I replaced it. After the first 10 minutes of unsuccessful firing, i took it off to check it and it was full already.

I'm beginning to think I shouldn't have purchased this car, even as cheap as it was.Just to verify, you're cracking the hard lines at the injector, no? I usually leave the top bolt for the spin on slightly loose and pump the primer or turn it over until it leaks a lot (seems like no more air escapes) and then tighten it down, give it another couple of mins of hand pumping and it fires right up. Prolly a good idea to replace/repair the primer now if you haven't already done so. I've only had to crack the injector lines once and that was after IP replacement.
