Car Forum / Porsche / Porshe 944 / October 2005why wont my car start?
i previously posted that my shifter was out of wack. i believe i fixed that by adjusting the linkage on the back of the tranny. seemed to glide right in while i was parked. so, i gave the car a wash, and sprayed some of that engine degreaser on the engine so i could clean it and maybe see where my minor oil leaks are, if there are any. i followed the instructions as the can said, and rinsed it after about 20 minutes. i let the engine dry a bit while i washed the rest of the car, cleaned the inside, and just made it look good. about 3 hours after i washed the engine, i went to drive it. it cranked and cranked and cranked, but would not turn over. i just tried starting it again (about 4 hours later), and still nothing. anyone have an idea what may be going on? my guess is that something got water in it that shouldnt have somehow, and it just needs to dry. but what could it be. help me please. dave 87 944na Pull the plug lead off #1 and use a plug to check for presence of spark while someone cranks the engine for you. If you sprayed gunk on the upper back part of engine you may have water in the engine sensor connections. check for water in distributor cap, dry the ignition wires, >i previously posted that my shifter was out of wack. i believe i fixed that > by adjusting the linkage on the back of the tranny. seemed to glide right [quoted text clipped - 12 lines] > dave > 87 944na well, i just checked all that, and nothing happened. when i crank it, every once in awhile it sounds like it wants to start, but doesnt. sounds like that when i quit cranking too. kind of like a sputter type of thing. when i crank, smoke comes out of the exhaust, so i assume there is still a spark. any other suggestions? thanks. dave found the problem. there was a small amount of water on the first spark plug (not sure which number that is; the one closest to the front). i think there is some in that cylinder too. i got it to start, but it takes a bit, and runs choppy when you rev the motor. it starts up quicker each time i shut it off and start it back up. so, my hopes are that it will take that little bit of water and just evaporate it when the engine gets warmed up. thanks for all the suggestions. dave 87 944na Dave, any moisture in or around the plugs will prevent proper ingition. Suggest you remove the leads and dry out each plug carefully. Then spray some silicon oil into each lead as you reattach it to the plug. This will keep the plug dry and repel moisture. Also preserves the rubber insulation. you almost for sure have bad plug wires or this wouldn't happen. the wires are good for aroudn 10 years, then they start to leak > found the problem. there was a small amount of water on the first spark > plug (not sure which number that is; the one closest to the front). i [quoted text clipped - 6 lines] > dave > 87 944na 10 years? what sux is that i just bought them last year. i got those magnecore ones. dont think i like them too much. probably go with oem this time around. if the wires are that new, even magnacore, they shouldn't be bad. how about the dist cap? it also goes bad (it gets carbon tracks and then becomes sensitive to moisture) > 10 years? what sux is that i just bought them last year. i got those > magnecore ones. dont think i like them too much. probably go with oem this > time around. nope. i changed all of that at the same time. i found a "package deal:" on ebay for under $200. bosch distributor and cap, copper bosch plugs, and magnecore wires. i changed them all the same day. it was only in the first plug. the wire at the back of the motor actually has a broken boot on the wire, and it didnt have any water. the boot was fairly snug in the hole too. is there any other way that water could get down there? thanks. dave 87 944na well, it's time for diagnostics - you symptoms sound to me like classic signs of weak ignition, which I know from my 944 cars almost always is due to either bad wires or a bad cap (or maybe a bad rotor, though I personally haven't seen a bad rotor on a porsche - I have seen a bad rotor on other cars). on a dark night (or in a very dark garage, open the hood, remove the under hood light (so it's nice and dark) and look at the plug wires with the engine running - if you see any glow or any light at all, they are bad > nope. i changed all of that at the same time. i found a "package deal:" on > ebay for under $200. bosch distributor and cap, copper bosch plugs, and [quoted text clipped - 5 lines] > dave > 87 944na well, i looked just now, and there wasnt any glow or sparks. i even did the whole squirt bottle thing that someone told me to do once. nothing. anything else i should look into? im slightly clueless at the present time. thanks again. Try removing plug wires one at a time and see if the problem is located on just one cylinder. Also, you will damage those Magnecore wires if you pull them off by the wire and not by just grabbing the boot. Use an inductive pick up timing light on each attached plug wire. If there is no spark or an interrupted spark on any of the cylinders, it will be noticable when you shine the strobe light on your palm or on a nearby flat surface. saw > Try removing plug wires one at a time and see if the problem is > located on just one cylinder.

I might be taking you too literally, but did you really mean that you found water IN THE CYLINDER or did you mean in the spark plug well? The only way water could be in the cylinder, other than the obvious blown head gasket, would be if you forced water into the intake manifold while washing the engine. This water would be injested by the engine when you tried to start it and foul the plugs. Did you pull the plugs and look at them?  SignatureI put junk in my email address to evade the spammers. Please take the junk out before replying. Sorry for the inconvenience.

I could crank over the engine and I could hear air hissing out of the cooling system. When I first saw this car last year it took some time to start and this got progressively worse. Owner said that lately it was leaking water and steaming. The engine was probably having problems for a long time. I had pulled all four spark plugs and all the electrodes were covered with water. It was the head gasket since I saw no cracks in the head or block and the head was true/straight. Now with the new head gasket it starts fast, but I still need to correct wiring issues to the cooling fans which I also just changed. later, dave (One out of many daves) > I might be taking you too literally, but did you really mean that you found > water IN THE CYLINDER or did you mean in the spark plug well? The only way [quoted text clipped - 13 lines] > > dave > > 87 944na People owning 944 etc. may be advised that only distilled water and proper coolant should be used. The aluminum block and head can pit and corode. You put tap water into the cooling system you are asking for serious problems. |
