So I've finally gotten my calipers back from the re-builders installed them and they seem to be working. Meanwhile we've been trying to get the car to run and it wouldn't keep Idle and felt like it was running on 3 cylinders. turns out one spark plug wasn't threaded in so we had an escapade trying to get that to go in. We just got it in and started the car up it sounds good when you give it a little gas and get it to 2000rpm but when you let off the gas the rpm drops to a rock to around 200 or so... Could It be bad gas? (the cars been sitting for a few years but we've drained the tank and put some new gas in) I was wondering how to set the idle to help the car run a little better and clear any possible bad gas from the fuel lines.
Come on I know some of you guys know how to do this.

We don't have the haynes manual yet but we just ordered one.
It starts but as soon as I let go of the key it dies

There is a screw on the throttle body just above the vacuum hose going to the dissy.
Unscrewing this will raise the revs but there is a lot to having the motor running right besides having the revs up.

Have u ever driven a turbo.

Ive tried adjusting the idle with no avail so I've averted my attention towards the fuel system. Im currently trying to find out if my fuel pump is working properly and was wondering which fuse goes to it? or is it a relay box? (it looks as though there are 2 empty spaces.)

you will have to look at valve timing, ign timing, fuel pressures and air/fuel mix.
its very possible vacuum lines are shot, fuel filter blocked or fuel pickup in the tank blocked.
The air induction into the throttle body can get cracked.
Bad leads plugs rotor dissy cap or coil.
Electricals get corroded.

Its a matter of working through one system at a time. have fun.

A little bit of an update, engine starts quickly, dies 2-3 seconds after starting, holding in the "new" hot start fix button allows the engine to limp along for a few more seconds. I'm not used to FI, SU, webbers, deorttos look simple compared to the fuel distributor.
Grounds we have been cleaning every ground we can find, many of the lights and electrical items now work!
With all the reading in the last few days, we look to be having a fuel issue, Does one need to purchase the K-jetronics fuel pressure test kit, or can one make a nice reliable one from???
Vacuum lines what do you guys recommend? white hoses look fine, those short connector hoses are sloppy, i did put some white petroleum jelly to help fill in a little with damaging anything.
My wanting to set up the idle is a carb idea, get it running an see what the Sun machine says. old habits.....
A little history on car we have had it a few years, it was given to me by a gentleman in town who described the "hot start problem" to a tee. The tank had a small amount of gas with stablizer, but wasn't as clear as could be, it has been drained, a few fresh gallons have been added, the "screen/filter" has been removed and cleaned, new fuel filter has been installed, lines were flushed, pump move allot of fuel! the injectors had been removed and cleaned by previous owner.
We learn more after the Haynes manual gets here but experience with them says there will be things not covered very well. Thanks for your time and help! tt

It sounds like the pump works when cranking but stops when you release the key which would give you a few seconds of running.
Fuel pump relay or wiring?

Fuel pump relay is located where????
tt

[Ozzie]

drivers side- fuse panel. on most its the top row 2nd from left

Normal relays will not work here. If you jumper pins 30 and 87 the pump should run for testing.

Thanks Ozzie, I owe you a pint of the golden liquid! make that a couple of them! tt

[oldgoaly]

just went out a tried to pull it out, seems like we may have some corrosion, this relay has a fuse on top? (bad shoulder/knees) can't see it to well. tt

[D Hook]

They're a sunofabitch to get out. I usually pull the one right below it so I can get a grip on it. (Just did one about 30 minutes ago.) I also take the onboard screw out of the aux. fuse panel just above the relays and rotate it away to get a better grip.

I believe the early cars had a fuse on the relay.
