2006 pontiac vibe intermittent extended crank, hard start

Post by borsheim1983 »

Hello.
My wife's 2006 Pontiac Vibe recently started to have an issue with intermittent extended crank and is often hard to start. It always starts, but one out of six times it will crank without start.

At first, not knowing what the issue could be, I had the alternator tested and it tested bad. I originally thought this was the problem.
I attempted to remove and replace the alternator, but the bottom mount bolt refused to give and I snapped two sockets on it. So I took it to a mechanic I know and trust and before replacing, he tested the alternator good with his test equipment. 14 volts going to alternator. So we left original alternator in. Two days later, same extended crank issue. I had the alternator tested at two different Autozones, both tests bad with 12.87 volts going to battery. So, I had the alternator changed, after bench checking the new one before installation. After installation, the car started fine. Again, two days later, extended crank with start on second attempt. I drove the car for a couple days and had one incident of extended crank. My wife again drove later and it extended cranked two times during her shopping excursion.
I again tested the alternator at one Autozone location bad, this time showing it was calling out the generator. The Autozone guy wasn't happy with me testing it again, not to mention requesting him to bench check the original alternator that I still had in the box in the back seat, but I wanted to eliminate bad actors. So I left Autozone #1 being told my generator was bad. Not convinced, I went to Autozone #2 across town and had the test done again....this time, it tested good, supplying 14 volts.

I am convinced I have an intermittent issue with the charging system. I'm not convinced it has anything to do with the extended crank starts......but it may. Thoughts? Other reading I have done points to ECM/PCM or EFI fuse. Suggestions? Thoughts? Recommendations?

My only thought would be to ask if the Vibe has had the ECM recall done?

There's a PDF attached in the linked post below that can walk you through checking.

If that's not it, I don't really have any other suggestions. Sorry.
Hopefully someone else will chime in, too.

There is a TSB that addresses this.
05-06-04-074C Intermittent extended crank at operating temperature. It requires a PCM update, which is $140 where I live.

Thank you for the TSB number and title! My daughter just bought her '06 Vibe and it had already had its ECM replaced long ago under recall. She was almost immediately after purchase complaining about the hard start issue once the car was warmed up .. I was just poo-pooing her away saying that's probably normal. Whod a thunk it?)

Here's my contribution back to the group. :D This was hard to find (and then reformat!! Sorry.. some of the intents don't want to line up right, but its good enough to walk in the dealers door with.)

Engine Control Module: All Technical Service Bulletins
Engine Controls - Intermittent Extended Crank/Hard Start
TECHNICAL


Bulletin No.: 05-06-04-074C

Date: May 24, 2010

Subject: Intermittent Extended Crank, Hard Start, Engine Cranks But No Start When Engine Is At Operating Temperature (Hot Soak) (Reprogram Powertrain Control Module (PCM)

Models:
2005-2006 Pontiac Vibe
Equipped with 1.8L Engine (VIN 8 - RPO LV6)

Attention:
Before proceeding with the reprogramming procedure in this bulletin, the Vibe Programming Application MUST be downloaded and installed on the PC. Refer to Corporate Bulletin Number 09-06-04-006A.

Supercede:
This bulletin is being revised to update the text in the Correction section. Please discard Corporate Bulletin Number 05-06-04-074B (Section 06 - Engine/Propulsion System ).

Condition
Some customers may comment on the following conditions:
- Intermittent extended crank or hard start when the engine is still at operating temperature (hot soak). Engine cranks for approximately three seconds, starts, may misfire after starting, then clears and operates normally for the duration of the drive cycle.
- The engine cranks but will not start.
- The technician may determine that the scan tool fails to initialize with the PCM and diagnosis reveals no injector pulse or spark during cranking.

Cause
These conditions may be caused by the following:
- The PCM calibration may not be maximized for hot restart.
- The PCM may have experienced an internal fault.

Correction
- Review SI for the symptoms and conditions described above. Refer to Diagnostic Trouble Code (DTC) List - Vehicle.
‹› If SI does not isolate a fault, reprogram the PCM with the latest calibration available.
- Use a multiple diagnostic interface (MDI) for reprogramming and ensure that it is updated with the latest software version.
- During programming, the battery voltage must be maintained within the proper range of 12-15 volts. Only use the approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
