Question Asked: engine won't start
January 15, 2011, 03:08 PM
I Have spark between no4 and no1 coil pack. I took the wires off and crank and the spark is jumping between the coil terminals very strong. Next I check for fuel pump operation and it is operating I also went to the fuel line and while cranking the car release the gas through the line to make sure I am getting gas. I am getting good gas pressure and good spark so the crank position sensor is not bad. Please tell me where to look next. I am about to do a compression test on all four cylinders to see if there is a possibility she jump timing. What other problems could create a no start condition in a Saturn. Cpt Trevor
Question Asked: Location of crank position sensor
January 12, 2011, 02:19 PM
Is it necessary to jack the car up to locate the sensor? My son was looking for the sensor from above the car and he can't locate it next to the oil filter under the manifold. Is there another position like close to the starter and if so is it necessary to jack the car to change this sensor and to locate it? Please if you have any other locations or suggestions on how I can advise him to help locate this please provide.CptTrevor

No diagnostic codes my car is in Colorado with my son and it won't start. I am trying to fix it from Florida it cranks but wont start and no spark. Check coil and wires and they told me ok. Bought a new crank position sensor to install but unable to locate the location of sensor on block. Could you please provide me with a diagram location or tell me where I can find the old sensor to replace it. Give me a good reference point close to and easily recognizable object on the block. Thank You CptTrevor

Question Asked: ABS light comes on and back pressure on pedal and noise when brakes applied
November 25, 2010, 12:25 PM
The ABS light on my dash comes on every so often when I shut the van off and restart it might come on again or sometimes not. When I apply the brakes it makes a noise and the pedal push back on me like a back pressure. I have brakes but I don't like the noise and the pushing back on the pedal. The master cylinder does not creep forward under pressure it holds. I check the vacuum for leaks and any damage to the valve I can't find any damage to lines or cracks. Could my ABS pump be making that noise when I apply the brakes? can I bleed the ABS pump or how do I check that to determine if it is bad .I have a my own scanners would this help me to tell if the problem is in the pump or wheel sensors? Please help I change the wheel cylinders front caliper, brake pads and still the problem with the noise and in my opinion some abnormal pressure on the pedal. Can you help me with a solution. I am a mechanic but I never encountered this problem before this is my own van. CptTrevor
Question Answered: wont start after stalled out on road

Check to see if you have spark first in the coil wire first before you condemn coil. If you have spark make sure you are getting gas. If you are not getting gas make sure you have gas in the tank and if you do change the gas filter. Then check the plug wires to see if they are firing if they are not change the pick-up coil in the distributor. If they are firing and it still don't start it could possibly be your ignition module located behind the battery on a heat sink.
