Hello All, I was driving on freeway at about 100kph when I observed some erratic warning lights on my instrument cluster. Low mineral oil etc. I then realised that I had zero acceleration as the engine just stopped. Fortunately other motorists allowed me to coast from the right lane accross to the left and then finally come to a rolling stop on the freeway shoulder. I cranked to no avail. Eventually the tow truck arrived and towed it home, and so it sits until my mechanic returns to open up in early October. I feel that this may be something simple that isnt apparent to me. I have pulled relays and checked fuses as I suspected fuel pump but really dont know how to check properly. Im not even sure that I pulled the correct relay for the pump. Im hoping that I can get some direction here. Cheers Charles | ||

A sudden failure is usually electrical. Fuel issues when they occur usually involve sputtering until the fuel is burned off. I suggest cranking and looking for a spark at the plug itself. No spark, it's the coil or module. | ||

Thanks Robert, Certainly makes sense. Ill investigate in that direction. Cheers | ||

Hi not sure of 94 is it coil per cylinder or twin distributors? I've known the ign relay to fail. Check for over heated fuses. Good luck Mike | ||

It could be as simple as a loose battery connection | ||

G'day everyone,.... You mention low mineral oil warning light? Is there a safety cut out for the ignition if the fluid level drops so you will have enough brakes to stop? Graham. | ||

Hi All, Just in answer to some of the questions and a further update. Firstly its a coil per cylinder setup and both hydraulic reservoirs are full to the top so cant understand the low mineral oil warning lights before the motor just stopped. Today I tinkered with electrical and found that the fuel pump relay wasn't tripping during cranking. Manual actuation of its internal contacts resulted in a fuel gushing noise within the fuel pipes in the engine bay. I then checked the fuel cutoff inertia switch and found it to be operating correctly. I decided that since I manually pushed fuel in the lines that the motor would at least fire up during attempted start but that didnt occur. I checked for spark---there was none. So here we are, no fuel and no spark. Is there a protection circuit that cuts both off whilst driving or how about a crank angle sensor scenario or worse, the whole engine control module. Your thoughts? | ||

Immobiliser maybe? have you ever changed the battery in the module? Ign relay by the fuse box? Do you have supply to the fuses at all? Mike | ||

UPDATE. Its fixed. After a sleepless night and a bit more research I was lead to the main engine relay that was nicely disguised as one of the others in the block. I put a tester on it, no resistance, I pulled it apart and there is a resistor inside that just crumbled. When placed back in the car without its cover I was able to manually get the contacts to touch during cranking. She fired right up. I've got 2 coming by express post. Thanks to all for your input and collective wisdom. Cheers Charles | ||

Well done. Happy motoring. | ||

Ive found it good practice to always change out any relays in any circuit that I am having problems with as a FIRST action to trouble shoot. Have replaced many relays in 2 years solving several issues. And have gone down many rabbit holes when I didn't! |
