[Solved] Fiat Grande Punto 1,2 \ 8V \ 48kW - The starter does not turn.

Padrettini 30726 17
Best answers

Why does the starter in a Fiat Grande Punto 1.2 8V not turn even after replacing the starter motor?

A faulty relay in the engine-bay box can stop the starter from turning; in this thread that relay was the actual cause of the no-start problem [#17119252] Before that was found, the main advice was to check whether voltage reaches the starter at all, because if it does not, the ignition switch/cube or the start circuit should be examined [#16961739] The ground connections were also flagged as important: battery-to-ground, battery-to-starter, and the body-to-engine ground strap [#17027872][#17030067] If power does reach the starter, then worn starter brushes were suggested as another possible cause [#17017599]

    Hello,

    I have a problem and I am asking for help.

    For some time he had not "turned" the starter and I started the car on "push". Before the complete "death" of the starter, this one twirled from time to time until it finally fell.
    I replaced the starter today. I connected everything as it was. Satisfied, I sit down in the car, turn the key and ... nothing. The new starter also does not "spin". I have a new battery (about 2 months). I checked the fuses, etc. The car fires on "push", but this is not the solution. What else should I check? Maybe replace something? I am asking for ideas and suggestions because I have run out of them.

    The battery voltage is 12.2V. After turning the ignition key, the voltage drops to 11.8V. Charging is 13.8V.

    Does it matter if it doesn't spin at all?

    No ... if he was shooting and not sunbathing it like that.
    And you must buddy check the starting circuit and the weight of the engine

    Buddy, check if there is electricity to the starter, if not, it is rather the ignition cube to be examined.

    I'll check everything over the weekend.

    If there are any more ideas, I will gladly accept them.

    A strange thing. On Saturday, I did not have time to combine the installation. On Sunday, I get into the car and, as always, trying to fire from the key, the car fired normally and continues to fire. I don't know what happened but it's ok.

    If he doesn't want to shoot, charge the battery. Had the same thing, ended up replacing the battery.

    I have a new battery. Bought in early December.

    Unfortunately, Punto went on strike again.

    It wont start.

    Bendiks bounces.

    Does the start signal go through any relay? If so, which one is it?

    Because if it comes, it may be the end of the starter brushes.

    I took apart the cover under the steering wheel.

    The cube and pins on the ignition switch look ok.

    When firing, I moved the cables and nothing happened. It did not fire.

    Fiat Grande Punto 1,2 \ 8V \ 48kW - The starter does not turn. Fiat Grande Punto 1,2 \ 8V \ 48kW - The starter does not turn.

    There is a 1-pin socket at the ignition switch. I have not seen any cord with a plug hanging anywhere.

    The starter is new.

    You probably have problems with ground. View the ground wire connection [no contact].

    Are the ground wires only at the engine? If so, how many are there? I only see 1.

    Ground cables; battery-ground, battery-starter, body weight - engine.

    Sorry for being so late. Problem solved. The relay in the box by the engine was the culprit. Thanks to everyone for your help.

Topic summary

✨ The discussion revolves around a Fiat Grande Punto 1.2 8V experiencing starter issues. The user initially faced a non-functioning starter, which was temporarily resolved by push-starting the vehicle. After replacing the starter, the new unit also failed to engage. The user confirmed a new battery and checked fuses, but the problem persisted. Suggestions included checking the starting circuit, ensuring power to the starter, and examining ground connections. The user later discovered that the issue was due to a faulty relay in the engine compartment, which was ultimately replaced, resolving the starting problem.

FAQ

TL;DR: Fiat Grande Punto 1.2 no‑crank fixed by replacing 1 failed engine‑bay relay. "The relay in the box by the engine was the culprit." [Elektroda, Padrettini, post #17119252]

Why it matters: This FAQ helps owners quickly isolate no‑crank faults (relay, grounds, ignition switch) and avoid unnecessary starter swaps.

Quick-Facts

Quick Facts

What finally fixed the forum author’s Grande Punto no‑crank?

The root cause was the starter relay inside the engine‑bay fuse/relay box. Replacing that relay restored normal cranking and starting. [Elektroda, Padrettini, post #17119252]

My Punto bump‑starts but won’t crank—what’s the most likely culprit from this case?

In this case, the engine‑bay starter relay failed. The car push‑started fine, yet the key produced no crank until the relay was replaced. [Elektroda, Padrettini, post #17119252]

What does “Bendix bounces” mean here?

It describes the starter solenoid engaging with an audible click while the starter motor itself does not turn the engine. [Elektroda, Padrettini, post #17017385]

Where are the key ground cables I should check?

Verify the battery‑to‑ground strap, the battery‑to‑starter cable, and the body‑to‑engine ground connection. Clean and tighten them. [Elektroda, triakw, post #17030067]

What battery and charging voltages were observed in this thread?

Battery measured 12.2 V at rest and sagged to 11.8 V with the key turned; charging system output was 13.8 V. [Elektroda, Padrettini, post #16960479]

Can a brand‑new starter still fail to crank the engine?

Yes. In this case, a new starter still didn’t spin because the relay path was faulty. "New starter also does not spin." [Elektroda, Padrettini, post #16960479]

Is there a starter relay on the Grande Punto 1.2, and where is it?

Yes. The successful fix replaced a relay located in the engine‑bay fuse/relay box next to the engine. [Elektroda, Padrettini, post #17119252]

How do I rule out the ignition switch (“cube”) quickly?

Access the switch under the steering column and inspect the block and pins for damage or looseness. The thread author’s looked OK. [Elektroda, Padrettini, post #17027822]

What quick 3‑step test helps diagnose no‑crank on this car?

  1. With a helper turning the key, check for 12 V at the starter’s small control wire.
  2. If absent, trace back through the ignition switch and relay.
  3. If present, the fault is downstream (starter/brushes/ground). “The basis is: check if there is electricity to the starter.” [Elektroda, migmig85, post #17017599]

Could the problem be intermittent and then return?

Yes. The author reported a day when the car started normally after prior failures, then the no‑crank returned later. [Elektroda, Padrettini, post #16999140]

Does the solenoid clicking automatically mean the starter is bad?

No. The solenoid can click while the relay, wiring, or grounds prevent motor current flow. This thread ended with a relay replacement. [Elektroda, Padrettini, post #17119252]

What practical sign shows the ignition area isn’t the main issue?

Inspection found the ignition switch block and pins visually OK, and moving the harness while cranking changed nothing. [Elektroda, Padrettini, post #17027822]
