New to forum and have some questions

[Steveo_32]

Hello guys and gals, Im new to the forum and just picked up my first Porsche and have a question or a few.

I picked up a 1983 911sc targa but it is a barn find. The car has not been run in 10 to 12 years and before I really screw it up I thought best to ask others what to do in a situation like this.

My thoughts are 1) drain all fuel, remove fuel tank and clean, new fuel filter, and inspect and service plugs, cap rotor and service oil as well.

I tried a little to fire it just to see and the results were a single backfire once and just continues to turn over with no firing of any other sorts, i tried about four times and the same result. so i have just moved the car washed it up and inspected items on the car and that is the point of where I am at.

So advice? How to approach this un-run fuel injected project.

Please school me!

Hey Welcome Aboard!

I would also swap the gear lube and re-pack front wheel bearings.

As far as the injectors, If you suspect clogged injectors have them serviced.

As simple test, if you have a O2 Sensor, connect it to a Digital Volt Meter and ground. Start the car and after a minute or two, disconnect #1 and note the reading, plug it back in then move to the next. if you get an obvious off reading, that injector may be suspect.

A can of BG44K or SeaFoam can get any remaining crud or moisture out of the fuel line system as well.

Welcome to the forum, and congrats on the purchase, I also have an SC Targa and love it.

There is a lot that could be wrong and cause the non start but your ideas for what to do are a great starting point. Use the search function here to check out other similar threads. Many people have bought these cars in the same shape as you and document the process very well. I would also pick up the 101 projects book as well as a copy of either the Haynes manual or the full shop manuals for reference.

With barn finds that "ran when they were put away" the issues tend to never be super serious. I would how ever check all the grounding points, and clean them to good copper with sand paper. i would also check the fuse panel, clean all the tabs to clean copper and replace all the fuses. and look for blown ones. If im not mistaken the 83 had the Lambda system. I dont know much about it as my 78 does not have it, I do know it has a relay some where that can go bad and need replacement you may want to look in to that.

Some other things,
Post your location so that locals can help you out with advice on good shops, or just help you with work on the car.
What are your mechanic skills what kind of projects are you willing to tackle?
What are you looking to get out of the car, daily driver, restoration project, weekend fun car, auto cross menace, track weapon?

Regards
Dave

Well Im a car nut, love em! Not scared of much, just never played with Bosch injection, Correction years and years ago my sister had a rabbit.....1984.......So this injection looks alot like her old injection, and i did not have alot of luck back then.
It was 15 or more years ago hence the asking nice injection question now because i have learned some since. I should have used the search function first!!

man 10-12 years is a long time in a barn, have you been trying to fire this thing without changing all the fluids yet? Cuz thats doing damage!

Everything you listed needs to be done, but if your gonna be driving this for ANY period of time at once, you gonna wanna change out all the rubber for fuel lines, oil lines etc.

Just off the top of my head heres a list to check
- Hard Fuel lines (are they leaking? they could have alot of gunky gas in them, may need to pull them off and clean out thoroughly)
-Soft lines fuel(Gonna need to be cleaned as well, and checked for cracking, leaks, may need to replace them all)
-The CIS system will need to be cleaned as well, and your FPR is prop shot
-Brake lines check for wear and cracking
-Tran oil
-Engine oil/ lines
- cv joints
- brakes/ rotors


To be honest with you, I would just pull the motor and transmission and give everything a good hard cleaning, new fluids, and checking all the systems. Than I would scrap the CIS and go with a Megasquirt conversion. Bitz Racing makes a steller kit, and they're directions are so easy to follow! CIS suck to begin with, one thats been sitting for 10 years prob sucks more!

My biggest advice to you is don't rush this process! Make sure you go over the entire car complete front to back. I skipped some parts when I first did my 914, got it running over the weekend, took it out for a test drive.... brakes where working when I first started, had I noticed that my front right line was severely cracked I prop wouldn't have run that red light. I was lucky cuz my e-brake worked, but it couldn't have ended poorly haha

and ENJOY!

Congratulations to the SC Targa world! Don't sweat too much about getting the car moving again after 10 years or so. Like Dave said, if the car ran well before it was put away you should not have much problems getting it back on the road. I did that last year with my car after 16 years in hibernation. I saw posts of several other people recently recently wo faced the same situation. If you search the forum you should find their threads. Ask here if you don't find them. Just don't be too hasty to turn over the engine before you have taken some basic precautionary measures.

First off.. get a fire extinguisher and keep it in the car. The temptation to drive these cars too soon causes, shall we say, burning issues. This cannot be overstated.

Secondly.. welcome! 15 years ago you didn't have the ease of getting questions answered when looking at your sister's car so I'd recommend reading up on CIS and giving it a chance. Many here are not CIS haters and enjoy its simplicity.

Does the gas smell like old varnish? If so, be prepared to flush everything from tank to injector tip.

Besides the right size, type and newly inspected fire extinguisher, you can replace all the old rubber fuel hoses as you go thru the car - be sure to get them all

old fuel can be added in small amounts to a lawnmower or daily driver and burned - filter it first
- or you can air strip it (let it evaporate in a big metal pan), latter is not the safest

there is a very complete thread on getting a long stored car running

replace all rubber brake hoses with new rubber and flush the system out (the fluid is a hazardous waste, so dispose of as per your town's laws - usually you can take it to an oil change place)

you will need new tires before driving it

you will also want to replace pretty much every bit of rubber & plastic on the car - suspension bushings for sure, window seals, etc.

do the safety stuff first & work your way thru the thread you find when you search for: long term maint.
