2001 Volvo Car will not start

BlackVolvos80 · Post by **BlackVolvos80** » 13 Jun 2015, 15:20

I recently purchased a 2001 Volvo S80. It has had a hard start from the second I purchased it, but being as though I am pretty savvy with cars I assumed a good tune would fix it. Well before I could even get to performing a tune up, the car decided it no longer wants to start. Since then I have checked codes and got a p0717 "Transmission related code" I pulled the etm out and cleaned it. within the etm itself was a mess of motor oil which I cleaned out, not sure how oil ended up inside of it? The etm has a yellow sticker from 2005. I replaced spark plugs and checked spark which checked out good. Fuel pressure jumps to a little over 50 psi when priming. I replaced the battery which was still under warranty. I have checked every relay with a external 12v battery and can hear each one click. Starter works well and cranks hard. I have checked all grounds and fuses. Timing belt looks good. Now for the weird part, when I go to put the car in the ON position immediately the etm will start clicking constantly and the fuel injectors also start to spray as well as a clicking sound from fuel pump relay. Also the tach jumps up and down with the key switched to the on position. If I crank the car for over 6 seconds I will always get a backfire from the intake. This car has me so confused and all the shops I call do not want to work on Volvos. The car only has 101,000 miles on it and everything looks in great condition. Thank you so much for your help

Well i would say code p0717 it's your main problem bc is the one who reads rpm on turbine if you have no signal on that one computer doesn't know when to fire up...keep me updated ..please...

I just got the car back from the mechanic today and he says timing belt jumped a couple teeth. He did a compression check and ( #1 50psi) ( #2 75psi) ( #3 100psi ) (#4 90psi) ( #5 90psi) ( #6 75psi). He also said valves are not bent and quoted me $2000 to replace and reset timing belt . Resale of these cars aren't much so I figured It's not worth dumping that much into it. So I will buy the timing belt kit and replace it myself. I am just not sure how to set the timing. I know I need cam locks which I heard autozone rents. He didn't mention anything about p0717 causing a no start and the only thing I can find for that code is shifting problems. The transmission is the GM model and was rebuilt.

Lots of tutorials here on timing belt replacement. Costs about $160 for an OEM set. Anyone who quotes $2,000 for a timing job is either scared of Volvo cars or is milking customers. Even a Volvo dealership would charge less than $600 without water pump I'm certain.

The cost of living in South Florida is ridiculous. Could a code p0717 cause a timing belt to jump? I guess what I'm saying is would it cause one of the cams to spin slower then the other resulting in a jumping belt?

Codes can't cause physical phenomena. They are just a report of conditions. If a timing belt skips it's because of a loose tensioner, a failed bearing in the timing system or a dodgy water pump.

Other reasons can be oil on the belt from a leaking seal or a sudden engine stop such as when an accessory belt wraps around the crank during engine operation.

Sorry, I meant being as though the vehicle is seeing p0717 (turbine speed sensor/low or no signal) could that in any possible way be tied in to the timing belt jump? Or do I just have 2 separate issues. Thanks for your reply

Hello Blackvolvos80,

I have exactly the same issue on my Volvo S80 commuter car.
My mechanic quoted $2K (parts & labor + 6 months warranty) to swap the engine with a low mileage engine. May i ask if you were able to fix yours?

I have been debating if its worth spending $2K on a 15year old car that has resale value of $2.5K.
The car is also serving as our family 3rd car or commuter car.

And I have exactly the same issue also. I am suspecting the crank sensor or fuel pump. No enough pressure (and flow) out of the fuel pump, but I also have a backfire sometimes when trying to start, which makes me suspect timing.

I did get it running after fiddling with some things. Put it all back together, and won't start.

Now that I think about it, I had the crank and cam sensor wires loose when it ran. I fitted them back down alongside the starter when I tidied up. Could I be seeing an EMF issue from the starter interfering with the sensors (particularly the crank sensor). The starter is certainly drawing an incredible amount of current out of the battery. I will try to report back.

437: TCM-0023 (P0717) Input speed sensor. Signal missing. Permanent fault

Diagnostic trouble code (DTC) information

D4301803 Condition
The transmission speed signal is transmitted by a sensor on the transmission. The transmission control module (TCM) uses the signal to determine the input shaft speed after the torque converter. This signal is used to compare the transmission speed and vehicle speed. The transmission control module (TCM) uses this comparison to calculate gear-shift timing. Engine speed (RPM) and vehicle speed data affects the adjustment of system pressure, lock-up function control and engine torque reduction. The result is smooth gear-shifting. The control module calculates and compares the transmission speed, engine speed (RPM) and speed at the transmission. Diagnostic trouble code (DTC) TCM-0023 is stored if the control module registers that the engine speed (RPM) signal is missing.

Substitute value

No torque reduction
No lock-up

Possible source

Contact resistance in the terminals.
Open-circuit on power supply.
Open-circuit in the signal cable.
Defective input speed sensor.

Fault symptoms

General orange warning lamp lit.
Malfunction indicator lamp (MIL) lit.
No lock-up function.
Harsh gear shifting.

Hint:
Harsh gear shifting can be caused by:
No reduction of line pressure when shifting.
No reduction of line pressure when moving the gear selector between positions P-R, N-R and N-D.
No torque limiting request to engine control module (ECM) when shifting.
