930 won't start

1986 930 turbo totally stock and unmodified. Has been sitting for a long time. Had the fuel dist. changed last year. Was running ok, then died and went to restart and popped a few time.

The things I have done are to check if both pumps run, yes.
To check if the spark is good. Pressed the sensor plate and it fired up and ran for a sec and would not restart.

The leakdown was great at 2% equally. I guess I have to check some stuff but where do I start?

Thanks for any help,
Mark

I have seen the mass-air get sticky after sitting for a while, the best thing to do is what 930zx stated. It is a little bit of a pain to run the old gas through though. I got my 86' that had not been driven in almost a decade with a half a tank of 93' from 98'. So I drained the tank, replaced fuel and attempted to start. Long story short, I ended up running the car on starter fluid until it passed the new fuel through the distribution block, took a long time, so dont get discouraged while you do yours.

Without a doubt it's the flux capacitor not discharging. Or possibly the wastegate support hanger bearing. Though it could be that darned Nancy Pelosi thing again

Yes Dan, those flux-capacitors can be a real problem, I also have had problems with the blinker fluid....

Darn that flux capacitor.

Dear Dan,

You found me!

Well it seem's to have me stumped. What was that " CIS separates the men from the boys?"

If you have time call me.

Suck, Squeeze, Bang, Blow, Dats what make the motor go (unless it's a dirt bike or Detroit)
CIS= Constantly it sucks
No Spark or no fuel ?

Not an x rated forum

Dear Dan,

I just want you to know this is a clean post and we won't have talk like that around here.

Any way, I am pretty sure it is not getting fuel on startup for some reason. I can get it to fire as soon as I slightly depress the sensor plate. As soon as I do the pumps run and I hear the freq valve runnin.

It fires right up and then dies. It won't refire unless I depress the sensor plate again.

I hate bothering you for this but, I know you know.

Is Nancy Pelosi a Republican?

Really thankful,
Mark

Gary,
I've been too busy looking for G car headers on Dipwad.com
Marky,
Have you checked the op. of the cold start valve? You've got to pull it out and watch it spray. After that vac leaks then mixture then pressures. I'd pull out the nozzles and watch them spray I bet they're clogged with shiite. Heard about your boy George's new plan B? I think he's calling it Operation Deja Vu

930 will start!

Dear 930 dudes,

Thanks for all your helpful advice and comments, the fix is in.

Dan, you were right on the money, the vac leak bug strikes again.

The fitting in the center of the intake plenum below the cold start valve for the warm up idle bypass valve blew out of the intake manifold.

Leaving a quarter sized hole to suck in free air. I guess there was too much sucking here!

A little JB weld fixed the fitting in there for good. I think it was swaged or epoxied in or something, CARS!

Thanks,

Mark
