Re: crankshaft position sensors
The top one is very easy , the bottom one is blocked by the oil filter adapter. Since you are going to loose a lot of oil when removing it you, might as well do a full oil change.

Re: crankshaft position sensors
CE OR SES light on? Have you checked for codes?
Are you getting spark? Fuel pressure OK? Will it start with carb cleaner sprayed into intake? Kind of putting all your eggs in one basket, here.... |

Re: crankshaft position sensors
Is there any coolant in the oil? Northstar engines in this age group are notorious for blowing the head gaskets.

Re: crankshaft position sensors
let me give you more background on this problem.about two weeks prior to this no-start problem i was driving home from work on night and the car just suddenly felt like it was out of gas,no response when stepping on the gas pedal,popping/back firing sounds and the SES light came on..i coasted into the nearest gas station and filled it up thinking low gas may have been the problem?the car seemed to run fine for the next 2 weeks and the SES light never came back on.about 2 weeks after this incident i pulled the car into my driveway one night,came out the following morning and the car would not start,just cranks and cranks but will not start.i did take a fuel pressure reading at the time,the best i recall it was around 37lbs..i know normal for this vehicle should be around 41-47lbs but even after installing a new AC/Delco fuel pump around 4yrs ago it always read around 37lbs and ran just fine..fuel filter and FPR were also replaced about 4yrs ago..i don't think it's a fuel related problem but not totally sure..so that's where i stand,the cars been sitting dead in the driveway for about a month now.can not get it scanned without towing it to a garage..any ideas? thanks much

Re: crankshaft position sensors
I know that places like Autozone rent tools......not sure if they allow rental of scan tools.....
OR..... Pick up a code reader......$20-$40 bucks..... OR.... Check for spark.....if ok, spray carb cleaner into intake and see if vehicle starts.... |

Re: crankshaft position sensors
ok, finally had a warm day and got out to do some more tests..i'm ready to rule out a fuel problem..did another fuel pressure test,read 41lbs which is normal for this vehicle..also sprayed starting fluid into the intake,still would not start..pulled the vacuum tube off the fuel pressure regulater,no gas leakage so that's working fine.can also hear the fuel pump turn on when key is on.the no start is not related to a fuel problem..what next?
