HELP, serious electrical problem

[kiteman]

I have a Probe SU (Series 2) 2.5 V6. I'll chronicle the engine problem as it may help.
1 6 months ago the distibutor failed. Due to incredible expense (here in Australia) I had a 2nd hand one fitted which lasted only 3 days. Fair enough, it was probably as old as mine (about 125,000 miles). They fitted another 2nd hand one free of charge. This has lasted until now, I think.

Car was running perfectly then one morning would not start. This had happened once a long time ago. I re-set the fuel cut-out in the rear near the tank and it started first time. It ran perfectly for 4 days. Then, again it would not start (lost of battery but just not firing up, no spark).

The mechanic reckoned it was the distributor again so I had it lifted to a local auto electric mechanic.

He managed to get the dissy working well enough to get the car in and out of the workshop (to my surprise!).

Fitted a new distibutor (new but after-market brand I think). The car then ran perfectly while it was COLD!

Once it had warmed up, after a mile or 2 then all hell let loose! The engine completely cut out, then in again, then out again etc etc etc. Virtually undriveable. The rev counter was going from 3000 to 0 to 4000 to 0 to 3000. When it was at 0 the yellow "Engine" light came on. I managed to get home mostly in 3rd gear keeping the revs high. Next day, returning to auto shop it was exactly the same after warming up. Perfectly smooth when still cold.

The electrician has just fitted a new crankshaft position indicator sender thinking that this may be the cause but no change. The "Engine" indicator has not sent out any impulse indicating problem source.

The car does not idle, the revs run from 600 to 4,000 to 600 to 3000 to 600 etc etc etc...

Anybody have any ideas??? Any assistance is highly appreciated!

Don't know why I'm thinking alternator, probably not
related but worth checking

This sounds like the problem Crystal had but she and her mechanic could never find a solution. I think it will be something electrical, like Mark I am thinking alternator as our cars are susceptible to failure of this part.

You need to find a mechanic that can read the error codes, if any, and take it from there having said that it will be a process of elimination.

If you need to replace anything I can recommend this company in the USA (parts take 5-7 days).

However if you need it in a hurry then try this company in NSW (parts take 2 days).

Good luck and let us know how you get on.

Just FYI, I saw a Probe today at Deer park wreckers (Melbourne) with front end damage. Any Probers might want some typical/expensive parts from it. So letting your know.

Cheers.
