No start, but it cranks Ok? The PNP switch would most likely not even allow it to crank. The 3-3-5 code relates to a wiring problem between the ECU and TCM, they sit right next to each other in that box by the right front strut tower. Try pulling the harness off both and cleaning the contact pins with some contact cleaner and soft brush, might just be some corrosion, unless you see some obvious damaged wires around there. This is a strange code.
Here's what the shop manual says.....
Code 3-3-5 (Fault In Wiring Between TCM and ECM)
1) Check status message on Volvo Scan Tool (998-8686). If
status message is PERMANENT FAULT, SIGNAL TOO HIGH or PERMANENT FAULT,
SIGNAL TOO LOW, go to next step. If status message is INTERMITTENT
FAULT, SIGNAL TOO HIGH or INTERMITTENT FAULT, SIGNAL TOO LOW, go to
step 3).
2) If fault is permanent and signal is too high, check wiring
between ECM terminal B26 and Transmission Control Module (TCM)
terminal B15 for a short circuit to voltage. If fault is permanent and
signal is too low, check wiring between ECM terminal B26 and TCM
terminal B15 for a short circuit to ground.
3) If fault is intermittent and signal is too high, check
wiring between ECM terminal B26 and TCM terminal B15 for an
intermittent short circuit to voltage. If fault is intermittent and
signal is too low, check wiring between ECM terminal B26 and TCM
terminal B15 for an intermittent short circuit to ground.
That's all pretty worthless unless you have a Volvo scantool and the wiring diagrams.
