1985.2 Porsche 944 has no spark


I would take a hair dryer and start to blow dry the coil, all the electrical wires that are attached to the ignition system, is a 12v tester to check primary circuit ( clip the coil + and touch the ground to see if you have elec flow, touch the frame of the car ) if it lit up then I would take the coil to have your mechanic check out if the coil is ok. Then get one of those spark plug wire ignition tester, it just clip on to the ignition wire and turn the motor, just test all 4 wire just to make sure, then the last thing to check is spark plugs, u can remove them but have them rest touching the engine block, turn it over n u shud get sparks going, o/w is the plugs, just replaced them is only like 10-12 bucks each.

I have a 1985.5 944 porsche and it doesnt spark everytime when turned over. it usually takes a few trys. what would the problem be?


How do you know it is spark? Pull the coil wire and hold it 1/2 inch away from metal..Spark?
I would test the voltage to the power side of the coil, during starting how many volts?
Also, your description fits a fuel system leak down. and the restarting forces the pump to pump..

Hi my porsche 911 triptronic will not turn over, i have all dash lights,the battery is good when you turn key nothing happens


You need air, fuel, and spark for your engine to run. Did the car do anything strange before not starting? Does it crank and turn over? If so, you should check you are getting fuel. Check the fuel pump relay and fuel pump.

1983 944 porsche have good fuel psi at rail,spark at plugs, won't start 12.6 volts battery turns over fine


Only thing I can think off if you getting fuel and sparks, two thing need for engine to run my guess is the timing is off. adjust the the rotor by turning it small turn forward to backward, if that don't work than more likely it completely out of time, either the chain has stretch so far and jump time completely. have a compression test done also making sure you have good compression.

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...


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.

Car wont start .


You will not be able to hear the fuel pump on that model. First you have to determine if you get fuel and have spark. If it is a fuel problem, replace the DME relay first. Very common. They act up and fail without warning. Part is cheap and located in the fuse box. Next would be the fuel pump.
If it is spark related it may be the Flywheel Reference Sensors. There are two and the cost about $100 each.

Good Luck.
