Success! Almost complete success.
The car started and ran immediately upon replacing the pump. It made all
kinds of lifter noises and was badly missing and then settled quite nicely.
Brakes came up, steering came back, fluid went low, added some more, still
bleeding air out of the hydrualics I think but it is coming. After running
for quite a while it was still missing on one cylinder. The brakes felt
spongy, then fine, then spongy, then fine, which I assume is the bomb
priming itself. We drained the entire system. The emergency brake actually
came in to spec while messing with the car too. The alternator sounded a bit
grumpy at first but was giving 14V on the dash and I had 2 bar at idle after
it warmed up and it quieted down. No fluids were on the ground AT ALL after
everything warmed up. Cycled the steering and it came up to full boost. I
have no dashboard lights at all (warnings) except occassional brake light
flashing as the hydraulics come up. I have suspected that the booster wasn't
OK but I think it is fine. Brakes go hard after a bunch of pumps after shut
down and the pedal modulates fine. Need to bleed the brakes again but so far
OK. What I didn't have was a multifunction display or speedo or the OK
display. Must have a power or ground issue. That will be later. I also think
I hear the turbo spinning but didn't find out and no boost gauge so who
knows.
The issue is it is missing on one cylinder. All the injectors are clicking.
But it is missing and bucking badly. Put some Techron in and will run it
again tomorrow. Drove it up and down the road some and it is close to normal
including clutch, brakes, steering, idle stabilizer. But missing it is a bit
gutless off the stop so it is tough to drive it smoothly and you don't want
to be stuck on a hill right now.
Will start pulling plug wires and see if I can isolate it to a cylinder.
After that I will check wires and plugs again. But I am guessing one of my
injectors is grumpy and squirting instead of a nice cone. It did settle down
and almost idle normally and the fans all came on when they were supposed
to.
So after being abused for 5 years and probably not starting for at least 3
it's almost back. Have to get some more pentosin to top up the reservoir and
see if I can get the hydraulics to settle finally. I think I am still
pumping air around. The used bomb I got seems to be fine. Have to do a final
adjust on the emergency brake and put the heat shield and bottom plate back
on underneath. If I can get whatever cylinder it is to fire properly I think
I could get it inspected today.
Anyone had their injectors cleaned and redone lately. There used to be a guy
that did truck injectors that would do Bosch injectors for $10 a piece. Have
to find those old emails.
Going to get a nice bottle of single malt to celebrate.
Like Gene Wilder in Young Frankenstein... IT'S ALIVE!!!!
