In Topic: Stumped!!!!

I decided to have another crack at my troublesome car over the weekend. Bought a spark tester and result was that it has a strong spark on all cylinders when tester set with gap at about 8 mm. However the spark was orange/yellow. I would have expected to see a blue spark but maybe that's not the case with a coilpack?

I'm at the point where I think I need to take the car to someone who has good diagnostic equipment. If I have a fuel pressure problem for example, is this something a diagnostic device that reads real time data would pick up? it's  hassle to get the car to a garage so I just want to ensure the time and money involved would be worth it.

Cheers

latest update in the saga.....

I managed to get components off another motor which I heard running perfectly. Changed over throttle body, position sensor, MPA sensor , ICV. Did these one by one. Result ...absolutely no change. So i think I've eliminated these possible causes. Next step will be spark test. If this is OK then..... fuel pressure regulator (how do you test this?) and injectors.

This is beginning to !Removed! me off but I will get to the bottom of it.

Thanks again Tony for your extensive advice on troubleshooting. I'm sure this information will be valuable to others on this forum in the future. It will be a couple of days before I can get to the car to do the latest battery of tests. Have a couple of questions arising from your last message.

You say tests on sensors should be carried out with plugs connected which makes sense. Does this mean I need pierce the wire to get a reading or can I somehow get in the back of the plug connector? Don't want to damage anything in the process.

I see when reading various posts that coil pack seems to be a frequent problem. Is it possible that the coil pack is breaking down after initially getting power to the plugs? Looks like a betch to get at, maybe need to jack the car up and get at it from underneath?

Cheers

Kevin

Hi Tony,

Tried what you suggested. No change really. It is just on the verge of starting but does seem to be over-fuelling as you suggest. Sounds slightly healthier with foot flat on the pedal. I took out MAP sensor and it was clean but I guess it's impossible to tell if it is OK with only visual inspection . There is no hose attached to it, just a 4 pin electrical connector. How can I test it? If it had failed would there not be a fault code showing? I have a Memoscan U480 fault code reader. I don't think this is a high tech device but it does recognize correct protocol for this car's ECU. Cost $35 on Ebay.

Hi Tony,

Thanks for your advice. I tried what you suggested and I found that with the fuse removed the motor did run for a few more seconds after a couple of turnovers but then died. I then replaced the fuse and it wouldn't start. Sounds really close and some smoke coming out of the exhaust but the little furker won't go. Still stumped I'm afraid.
