1995 850 Engine died while driving, slow cranking

Post by nautalter »

Hi All

I have a Volvo 850, 1995, 2.5l automatic that has been driving me crazy not to mention broke.

Engine just shut down when driving, all warning lights came on.
The engine would not start again, turns over very slowly.
I have changed the timing belt, new one fitted and timing checked, has compression.
The starter motor was sent for servicing and has been confirmed to be in good condition.
All plugs new and leads, distributor cap and rota recently changed, gear oil clean and red.
Fuel pump recently changed along with fuel relay.

Without spark plugs in it still cranks over very slowly and does not sound very good.
After changing the timing belt and assembling everything it almost wants to start but i have a horrible suspicion it is not turning over fast enough.

I can't think of anything other than a gearbox, torque converter issue.
When running the diagnostics all functions seem to be correct.

Please can you get back and advise or make a recommendation.

Thanks
Mark

Why would the gearbox cause no start issues? Might be your battery is on it´s way out.
Very common issue could be rotten wires as well, especially the ones for the starter motor.

But then again, it died while driving. The timing belt didn´t break, right? These are intereference motors.

Do you have spark and or fuel?

Plugs and leads new, has got a good spark, fuel pump new.
When I eventually got it home the first place I looked at was the timing marks and belt, all in the appropriate position.
I installed a new belt as there was no record of it being changed an i have driven 60k since purchasing the car.
I removed the starter motor and had it overhauled, company said no issues with it.
The gear warning light has come on and off intermittently over the past year or so and when checking the fault codes nothing of substance was recorded. The only common one that crops up is the No Speed sensor although the dash instruments work.

The LCD does not work any longer and I suspect it is a dash processor fault.

This has happened before and usually when braking at a traffic light and then the engine dies. Normally it starts by the time the light changes, they are slow out here.

With the plugs out it cranks over slowly and doesn't sound good or normal or healthy.

I will take a look at the wires to the battery when I get home shortly.

If you have compression, then you don't have valve damage, and given compression, you "just" need fuel and spark. If you're cranking slowly, then the battery should be first stop. Hook up a booster or get a new battery, and see if you get the same results. Like Clemens said, checking your wires should also be up at the top of the list, long before timing belts and pumps, starters and that kind of stuff. :)

The battery is not very old and was fully charged when I tried to start the car after replacing the timing belt.
I checked the negative cable this morning and it looked good, no breaks, both terminals in good condition.
I added a set of jumpers to the body and negative just in case, not difference.
I tried a fully charged battery from my work car, fully charged, not much better.
I have tried jumping from my neighbors diesel while running and no difference.

All the cylinders have some compression with no.1 being the highest. Admittedly it is not as high as the manual says, but the engine is cold and has not run for 6 weeks now.

Don't just look at the battery terminals, clean them, they might just need oxide removed, this applies to both ends. Clean the battery cables on both ends of each cable, see if that makes a difference.

If cleaning the battery cable terminals does not make a difference .. Battery cables can be damaged under the insulation where you cannot see the damage. Use a good, heavy gauge, set of jumper cables to bypass the battery cables, see if that makes a difference.

The slowccranking is telling you the battery,cables, ignition switch, or starter are at fault. There may we’ll be more than one fault.

Turn the headlights on for 30 seconds, then turn off, then measure battery voltage.

The starting system is most likely at fault. Less frequent but still possible is excessive drag due to a defective Alternator, A/C Clutch or Power Steering Pump. Easy and cheap to confirm or eliminate the later, remove the serpentine belt.

Ok, I have a bunch of heavy cable and crimps at work so on the weekend I will run a new one for +/- and see what transpires. I cranked the engine without the serpentine belt on and no plugs in and it was slow then, that's why I removed the starter and sent it for inspection and servicing. Lug and cable at that end looked good. So I will spend another Saturday afternoon under a Volvo... Thanks for the assistance, I will update later.
