Question about Fiat 124

Open Question

FIAT 1.2 8V 2002. My engine check shows up and after diagnostics it says Ignition Coil 3/4 error. The error was removed and gone after I changed the Ignition Coil. However 2 days later it shows again and my car shakes a lot on start and during low-gas movements. I remove again the error with the computer diagnostics and the shaking is gone. However it comes back after 5 seconds. I have deleted a few times and it shows again. Solutioon?

check to make sure #5 spark plug wire isn't bad,make sure you have not wired it wrong from changing plugs. You should purchase a chilton manual if you haven't already

One question, have you replaced the ECTS (Electronic Cooling Temperature Sensor)? These cause no end of different seemingly unrelated problems on Saturns. Peice is about ten bucks and is an easy install. Just search on youtube for a how-to video. Even if that's not the problem it is reccommended to replace this peice just the same as they ALL end up going bad at some point.

If that's not a fix, start pulling plugs. Check to see if they're correctly gapped and if they have any damage/corrosion. If you're running Platinum plugs, immediatly change to a copper plug as Platinums have no place in these motors. Most people have the best luck with NGK copper.

Check to make sure that your plug wires haven't been crossed. This sounds like a plug or wire issue most likely so it has to be in that family, if the plugs are good, wires good and not crossed, sensors are fine, then time to replace your coil packs. If you've replaced everything up to the coil packs then that is most likely the cause of your dillema.

SOURCE: engin managment system light keeps coming on and off

The best ideea is to scan your Engine Control Unit with a VAG-COM, Bosch KTS, ... diagnosis tool. If you have one of these dedicated scan tools you will find definitely the engine fault code-"P...." and the clear description of the error. Also you can try to erase this error (or these errors) from the Engine Control Unit memory. If errors are "sporadic" type you certain have permission to erase them, also for some kinds of "static" errors. Because your Engine "MIL" - Malfunction Indicator Lamp keeps coming "ON" and "OFF" you have a big good hand to clean errors from Engine Management System memory. If you don't have any diagnosis tool, you can also try something else. For check up if the engine have a proper turn, you can successively disconnect each spark plug coil from the engine wiring system, engine idle, car stationary. When you operating this you must be free of chassis ground (battery ground)!!! When you disconnect a spark plug coil and the engine speed (rpm) drops, that means this coil works properly. When one coil disconnected and engine speed (rpm) still remain unaltered, this coil (or spark plug) is out of order. First you can change only the spark plug and check up again. If no changes the coil is defective and must be replaced! My recommendation is first to change all spark plugs on the engine, and after that check up coils. Please Rate my Response! Thanks!

Why wont my 2002 olds alero start when its cold out


One of the coil packs or the ignition module is probably bad. Test for spark when cold. If no spark on any coils suspect the ignition module or crank position sensor. If spark is gone on only one coil check the plugs and wires to that coil pack. If theplugs and wires are ok then replace thge coil pack. Don't forget the obvious load test the battery and clean the battery connections. If the check engine light is on run any diagnostic codes and repair

Trouble with escalade


Vehicles: Escalade, Suburban, Tahoe, Yukon, Denali, DenaliXL, YukonXL 1999-2005 with Distributorless Ignition System

Normally I'd recommend that you check your ICM (Ignition Coil Module), but the ICM in this vehicle is an integral component of the PCM (Powertrain Control Module), and is not separately serviceable.

In the US, one can go to Advance Auto Parts/AutoZone/Pep Boys, and get a free "ignition system check" which will tell you whether your alternator/voltage regulator may be failing/marginal. Also, by disassembling your battery and carrying it into the store, you can get a free battery load test on their in-store tester.

Also, you'll want to get a free "Check Engine Light" test from Advance/AutoZone/Pep Boys, since that'll give any DTC (Diagnostic Trouble Codes) that the car's PCM may have stored. Once you have any DTC's stored by you car's computer, check the chart at the end of this solution for their interpretation - codes whose numbers exceed 1000 are Cadillac-specific codes. All of the included codes are stored in response to ignition coil faults.

These instructions apply whether your Escalade has a 5.3L or 6.0L engine.

SEC 1
---------------------------------------------------------------------------------------------
Adjustments - Ignition Timing

Ignition timing is preset and cannot be adjusted. Ignition timing is controlled by the Powertrain Control Module (PCM).

On V6 motors the distributor is located in a fixed, non-adjustable position. DO NOT attempt to rotate the distributor otherwise damage may result.

On V8 engines the distributor can be rotated for proper alignment of the rotor to the cap. The engine base timing is not adjustable by rotating the distributor.

The 4.3L, 5.0L, 5.7L and 7.4L engines use a distributor ignition system.

The 4.8L, 5.3L, 6.0L and 8.1L engines use a distributorless ignition system.
--------------------------------------------------------------------------------------------
SEC 2
--------------------------------------------------------------------------------------------
Distributorless Ignition System - Description


The 4.8L, 5.3L, 6.0L and 8.1L engines do not incorporate a distributor to deliver energy from a common coil to the individual spark plugs. The electronic ignition (EI) system is responsible for producing and controlling a high energy secondary spark. This spark is used to ignite the compressed air/fuel mixture at precisely the correct time. This provides optimal performance, fuel economy, and control of exhaust emissions.

This ignition system consists of a separate ignition coil connected to each spark plug by a short secondary wire. The driver modules within each coil assembly are commanded ON/OFF by the powertrain control module (PCM). The PCM primarily uses engine speed and position information from the crankshaft and camshaft position (CMP) sensors to control the sequence, dwell, and timing of the spark.

Car cut out and will no longer start. diagnostics showed faulty coil ignition pack which was replaced but still no joy. any suggestions? further diagnostics do not show any electric fault. timing ok.


Check all conections to the coil pack, check to insure all spark plug wires are on, and make sure it is getting fire. With the engine not starting, the check engine light may not come on to produce a code for the diagnostics.

1981 Fiat 124 Spider. No spark coming from coil.


Assuming that you have a fully charged battery then you should check/replace the ignition points and condenser. This should ideally have been checked before investing in a new coil.

If in any doubt then just replace them as it's cheap and easy. Note that most Fiat 124 Spiders are a little more complicated than normal cars as they're often fitted with two sets of points instead of the usual single set. One set is used purely for starting and the engine switches over to the other set once it's running at full oil pressure.

Assuming you have a 1600cc dual point 124 Spider then look at the following web address to see how to replace and adjust your points:-
http://www.mirafiori.com/~thad/points.html

Note that although the points can be set roughly using a feeler gauge it's vital to adjust them correctly using a dwell meter.

The next web address gives you the specs for the US specification Fiat 124 Spider which usually had a single points distributor (points specs on page 21):-
http://homepage.mac.com/tmckaskle/fiat/images/specs/index.html#page1

When doing this job also check and replace both the distributor cap and rotor arm if they show signs of damage, burning or excessive wear.

This is not a difficult job, but it is fiddly. I usually found it easiest to remove the distributor from the engine to work on it but that does mean that you need to mark the position of the rotor arm as the distributor is withdrawn to ensure that you don't completely lose the ignition timing when you've finished. You'll need to recheck and adjust the timing afterwards whether the distributor is removed or not anyway.

Finally, for lots of detailed help and assistance, I strongly suggest that you register on the Fiat Forum at the address below:-
