Engine woes

Engine cut out completely on the highway yesterday. Got it started again and managed to limp home.

First thought was PTU failure so switched to my spare. Problem still exists.

I'm now thinking FPCU or blocked filter or failed pressure regulator (the one that sits in the plenum). Or is it possible that I have 2 dud PTUs?

I'd appreciate your thoughts/help gentlemen.

Thanks
Cliff

 

Any fault codes, checked CAS connector?
You can bypass FPCU or just disconnect FTS to run @ full pressure - FPCU usually makes pump noisy for a few days then dies instantly. I've got a spare pump & FPCU.

Yell if you want a hand Cliff.

 

What do you mean limp home, would it start and idle but run like shit above idle? That happened to me on my bike and ended up being shity conections to the T.P.S

 

Ran normally once I got it going Vic.

I'll run datascan on it when I have a chance later today Rob. And try the bypass see if that helps.

Thanks for your input - I'll get back to you on progress later.

 

Only thing i can suggest is to check and clean all electrical

connections. i know my dodgy thermo and injector connectors can make the car run real shit if they get knocked... currently replacing them.
Other thing is to just disconnect the battery oc=ver night. then stop and sart her a few times and the ECU might reset. Worked for me (read my PTU swap post!)

 

Not good to hear Cliffy....

But unfortunately i cant help ya cause i dont even know what a FPCU and PTU are

Max

 

Cliff doesn't need to disconnect battery...

to reset ECU. He has datascan *wink*
Cliff, did the car suddenly die, or did it start to choke-cough-splatter and then die?
Could be SO many things, but I'm going to place a bet on CAS.
Good luck mate!

 

Choke-cough-splatter is what happened Jono. I'll check the CAS later today when I get a mo. Thanks.

Read your problems in the other thread Odin. I think Jono is right. PTUs usually fail when they get hot and the soldered connections break down. When the car cools down these connections make contact again and voila the car runs fine again. Best bet is to relocate the PTU to under the nose panel where it doesn't get hot and/or replace with a series 2 PTU. Unfortunately I don't think my problem is the PTU.

 

Update

Ran Datascan and came up with code 55.

CAS connector seems fine also.

Only problem I found was a lazy LH O2 sensor. I'll fix this when I finally get around to pulling the engine to fix that annoying exhaust manifold leak.

Engine would still only run for a few minutes before dying. Took fuel filter off and backflushed it and blew it out with compressed air. Seems to have done the trick. Blew out a lot of crap.

Rob (K-zed) do you have the full version of conZult? I'd still be happier if I could make sure there is no problem elsewhere that datascan hasn't picked up.

 

What are the major ramification of bypassing the FPCU? Could it cause a new fuel pump to become noisy and run at only 20psi?

I am trying to determine the cause of all my dramas and I am on holidays, so would like to do it now whilst I can.

Cheers
Rob

 

Cliff, I have ConZult ...

... but no cable at present. ConZult does no more engine-wise than DataScan but will test Auto/CC etc.

 

guys .. my "virgin" cable is available to borrow .. i can

deliver it before golf tomorrow(11:00am) if needed.... give me a shout ...

 

Sounds to good to be true Baz *wink*

Never mind the 'cable' .... she'll not get far! *2 x winks*

 

somehow my "cable" is missing from that quote .. never

mind .. i "reccone" it is way toooo short anyway .... lol..lol..lol....bad boys ..!!!
