Sons 1st porsche.

[mb911]

Yesterday bought an 88 944 that had been sitting for about 10 years " ran when parked" for my son who wanted a project car.. He cleaned everything out yesterday and today replaced the fuel tank to fuel pump line and put a little gas in it.. It has no battery in it yet but was able to use jumper cables to get it to turn over. It has compression, spark, and turns over so pretty excited about that. I however did not hear the fuel pump kick on.. Any suggestions to bring this beast back to life? Btw he's 17 and paid 600 for it .. I felt like it was a reasonable price what do you all think?

Chances are whatever fuel was in there has turned to varnish and is plugging up everything. Do an oil and filter change so you will be circulating fresh oil once you really start turning it over. Get a battery in it. Replace the fuel filter. Pull the fuel injectors and either replace or rebuild them. Then start following the no start diagnostics on Clark's Garage.

Should be a fun project. Good luck.

Excellent price! The '88 has a fuel pump tank strainer/in tank filter that should be changed along with the "O" ring seal.

Use of jumper cables should be avoided...



Nice car.

Yup gonna buy a battery tomorrow.. Fuel filter will be on my short list.. Tried getting the fitting out of the tank and was concerned as it was not loosening up. Any tips.. Don't want to break anything

On a 944, you won't really hear the fuel pump with the key on. It only runs while cranking or running. If it's been sitting for 10 years, I would highly recommend changing the timing belts as well!

Update:

Bought a battery and we have fuel up at the rail, have spark can't confirm fuel at the injectors yet but fairly certain I do. So far no fire.. What should we check next. Seems like it has the magic combo to get it started.

I really don't "get" the idea you can't jumper a 944.

I've had to do it on my car and those of others more times than I should care to admit. Never a problem, no special steps taken, like jumping any other car.

DME shouldn't see power until the DME relay turns on at cranking, and having another battery wired in parallel to your car's shouldn't have any meaningful effect on the current going into the DME.

Willing to bet the injectors are gummed up.

[mb911]

Is it worth trying to clean vs just buying new ones? Looks like new is 80-100 for a set?

[v2rocket_aka944]

be careful with injectors...
there are lots of cheap knockoffs of poor quality, as well as other car brand injectors that are "close enough" to 944 specs to work. you really need to get the Bosch part number of a prospective injector and compare it with the specs of the stock 944 units.

or you can send your injectors off to witch hunter, rc engineering, among other companies who will clean, service and flow-test your injectors for $22 apiece or so.

[mb911]

Thats a good idea.

[Fastbackjack]

I recently sent my turbo injectors to Witchhunter. They did an excellent job.

[pfarah]

I sent mine to Injector Repair, LLC a while back; they did a great job and at a great price.

[mb911]

Ok we will see what happens. Went to the zoo today and my son decided to work on the car while I was gone.. He took the injectors out, reference sensor out (he broke the connector) and worked on the headlights. Appears its missing a relay for the headlights.

[mb911]

Well got it running today yeah.. Fuel pump is junk but starting fluid did the job. He was excited.

[mb911]

Today finally car runs well. New used fuel pump from plyhammer.. Runs exceptionally well. Need to change some fluids and fix the master and slave cylinder and brakes and he will be able to drive.

[bumflick]

congrats. keep the updates coming.

[IdahoDoug]

Spray all the brake bleeders, the clutch bleeder and such with penetrating oil (PB BLaster or Kroil - NOT WD 40) so when you need to loosen them they will go easy. Nice job. Keep the updates coming. Pics of your boy having fun would be nice as well. My son and I just started on a red 1988 Toyota Supra Targa 5 speed. Engine's out, etc for serious work.

[mb911]

Update car is running and driving(down the driveway) required oil change, new speed and reference sensors, brake pads, starter, and still needing timing belt and a complete brake bleed to purge the water soaked fluid..

Pretty exciting for my son. Now to teach him to drive it..

[alfadoc]

Lucky kid. Congrats. I would STRONGLY recommend a new T belt, rollers etc before running it more. 8 bent valves would put a serious damper on a happy situation.
