I have a 2001 Volvo v70 crank no start car ran badly for a day or 2 then crank no start car does not have a PEM idid replace fuel filter have about 50 psi at fuel rail fuel seem to run does not seem to have spark with my tester any insight as to where to go next check coil for voltage ?? what sends power to coil ? did not see any bad fuses thanks steve 217 553 2110

I'd suspect the crank position sensor but have never had to deal with one so...
or ignition harness, see if you get v to the coils.
after cranking can you smell fuel at the exh pipe?

thank you jonesg
I agree that the crank shaft position sensor may be the problem does anyone have a procedure or method to replace with a picture I believe it is on the driver side down on transmission housing but not sure
I will check to see if I get voltage at the coils I did not necessarily smel fuel at the exhaust but I only cranked engine a few seconds so as to not damage starter
im trying to avoid throwing parts at the car I do appreciate all of the help steve

youtube is the second best resource for me after this forum.
Alldata internet subscription yearly is decent too.

- Google search "Volvo PEM".

- About $20 at local junk yard. About $50 on ebay.

Thank you cn90 for the response. The 2001 Volvo V70 apparently does not have a PEM. I had hoped that was the problem but obviously not. I do seem to have good fuel pressure at the rail but no spark so I do think that the crank position sensor is the potential culprit. I have ordered one and hope that it solves the problem. I appreciate everyone's ideas and will report back.

Let us know how this goes. The Coil packs get a constant 12 volts and get fired by grounding through the ECU, so a check of the bus voltage to the coils might find a fault.

that is very help[full. I am waiting for the crank position sensor but will try to check the voltage at the coil in the interim.
