Re: Dicato code problem
Hi to everyone in broken Fiat land. I joined the forum for exactly the code problem. I have researched using two brilliant guys for guideance; Many thanks Andy Hickling and Diesel Bob.
Now for what its worth, is my opinion, which you are entitled to!
Its all down to the immobilisor, Not the key, Not the ignition lock, Not the aerial, Not the black box or even the ECU. Its down to that Bl**dy solenoid in the back of the fuel injector pump. You can't get at it without breaking bits off you can't replace it without buying a new pump. My van was 100% reliable until it would not start one afternoon, since then the code light comes on when it feels like it on second and subsequent startups. Usually starts ok first thing in the morning but not always.
My theory, The solenoid gets sticky through being blasted with road dirt which WILL find its way in, one day it does not move any more. if it cant send a signal back to the ECU telling the ECU its working the system assumes its been tampered with and flags up the code waring light. Thats what its suposed to do, oh by the way the engine won't start because the solenoid is stuck and wont let the fuel through any way.
My cure;
Blasted lots of WD40 into any cracks and wiring holes next to the three leads. Turn on the ignition, then go under the bonet and disconect a battery lead. You will hear a click from the fuel solenoid next to the battery. touch the battery connection with the lead you will hear the fuel solenoid again, ignore this and listen for a quieter click from the solenoid at the back of the injector pump. repeat this again and again. All I heard at first was a faint buzz but after about 50 repetitions the solenoid began to click once more. If you attach the battery cable once you have heard the click (friction will do dont tighten it yet) go inside the cab you will find the code light has gone out.
I repeated this over about three days and all is well. I still lubricate the solenoid regularly.
If all this sounds boring try counting down the number of times you touch connect the battery, starting at 900 cos thats how many pounds Fiat are going to charge you to replace the pump. Doesn't seem so bad now huh!
