Question about Porsche 911

1 Answer

My Porsche won't start. I've changed all 12 spark plugs (it has twin plug heads), and am getting plenty of fuel into the cylinders (plugs came out wet), but still can't get it to fire. It has a Haltech ECU and individual throttle bodies. I've checked all the fuses and connections. What do you think I should try next?

Pull one plug out of one cylinder, and place the top of the spark plug on the body of the car(grounded). Start(or have someone turn the car over) and hold the plug to a grounded spot. If the plug sparks it is not an electrical problem. Also, if the plugs are coming out wet, your flooding the engine making start even harder. Also make sure the plugs are gapped to manufacturer's spec.

My truck got hot yesterday cause of a blown heater hose and it won,t start today , i,ve got fire and i can smell fuel , but it won,t start


The first question I would ask, Is it turning over? If not, pull the plugs, and see if there is water in the cylinders. Water won't compress. Second question, if it is turning over, pull a couple of plugs and see if you find any water. Because you may have blown a head gasket. If you have, make sure you send the head to get it checked for cracks before reassembly. Good luck!! DD

Check for compression on your cylinders. That would tell you if you have a bad head gasket or a bad head.check your distributer and see if is good, i seen that happend too

2000 dodge stratus wont start even after changing fuel pump


I think you are making some assumptions and may be overlooking the problem.
What is the actual fuel pressure at the rail ?
Are you getting a good spark at the plugs ?
Do you have normal compression on all cylinders ?
Is the check engine light on when you turn the key on ?

Grey or white smoke indicates a blown head gasket or a cracked head. Pressurize the cooling system and remove the spark-plugs and check for signs of coolant inside the cylinders

We have a porsche cayyne turbo s which is a 2006 model and it has been gas converted and has only done 600miles since and is now running rough and is saying it is miss firing on clynider 3 what do you...


only certain things can cause a miss only on one cylinder . faulty spark plug, faulty fuel injector, faulty coil, vacuum leak on intake manifold (plennum), valve issue, or head gasket issue. Being a low milage car would I would suspect possibly a clogged fuel injector or the spark plug.
The purpose of using a diagnostic scanner is one would be ableto rule out most of the possibilities looking at the data.

All you can do is replace or rotate the spark plug to see if the code folllows the plug and add some chevron techron fuel injector cleaner. Also use chevron 89 or 91 for a rew tanks because the fuel cleaner in thier fuel seems to be the best option for cleaning injectors and keeping them clean.

On a 1998 dodge stratus 2.4 ltr engine misfire


check compression,with engine running remove h/t leads 1 at a time to diagnose weak cylinder,check that cylinder has the same amount of spark ( jumps the same gap as others )try changing the plug from crook cylinder to a good one and note if miss follows that spark plug or stays with same cylinder,can do same with injectors but only perform one procedure at a time so you can determine which one works.

MY 535I JUST WON' START I CHECKED THE FUEL LINE AND THERE IS PLENTY OF FUEL COULD NOT GET A SPARK AT PLUGS


Possible bad coil pack, since the plugs are not firing work you way back to the coil pack which is the 50k-70k volttage box that send the sparks through your wires to your plugs.

Hi, I have a 1997 Porsche 993. Motronic 5.2 M07. I am getting these fault codes 1) 62 misfire emissions-relvant 2) 51 Cylinder 2 misfire emissions-relevant) 3) 54 Cylinder 5 misfire ...


misfire :-------- try checking your 02 sensors /fuel pump and filter.

for 51 cylinder misfire :---
Change the coil. Period. Very easy to remove from the vehicle if it's a 4 cyl. Follow that spark plug wire from the spark plug to the other end. What it's attached to you should replace
for 54 cylinder 5 misfire :---First you have to eliminate the most obvious problems, like spark plug and spark plug wire. If you replace those and you still have a misfire, then it's a good idea to look for a vacuum leak in the intake manifold
