Owner: Your vehicle's engine control computer provides a ground to close the fuel pump relay contacts for a few seconds @ key on, then that ground opens until the computer ( ECM ) sees a crank signal, at which time the ECM provides a ground to keep the fuel pump powered. I would suggest checking for power and grounds @ the fuel pump relay during cranking to confirm correct ECM operation. The best way to determine if the oil pressure sensor is a factor, is to connect a capable scan tool and see if the ECM is enabling fuel, which should be one of the parameters you can monitor.
Owner: Have some qualified to do so check the CVI Index readings with a good scan tool, these readings may give insight as to why the transaxle is giving you this symptom, possible incorrect clutch pack clearance, missing or out of position wave plate, incorrectly installed accumulator spring, excess final drive lash, failed engine mount, worn axle(s), or control solenoid issue.
Owner, There are many possibilities for that symptom, only a Professional diagnosis will answer your question.
Owner: The Estimates which you are able to generate on RepairPal are a courtesy service provided to give you, the consumer, a guide to check if the Prices you are Quoted are within normal guidelines for your area. They are not a " chiseled in stone" Quote from any shop. Most Shops follow specific procedures aimed at Customer Satisfaction & Trouble Free Repairs, for example: Replacement of the water pump during a timing belt replacement, when the water pump is timing belt driven. A quote in those instances may exceed the estimate self-generated by the customer. I hope this explanation may alleviate your concerns, if not, feel free to call us. Thank You.
Greg's answer is correct, what is the specific code ? If it is a catalytic convertor efficiency code, the catalytic convertor may have failed the test that the on-board computer orders as a programmed protocol, or you could have a vacuum leak, fuel injector issue, or a sensor slightly out of range. I often takes more than a code to diagnose a problem.
Owner: Was the vehicle diagnosed before repairs were made ? Fuel pressure check, Ignition system performance check ? communication with the Powertrain Control Module ?
Can you send a photo to 727-417-1908 ?
Owner: Fuel Pressure ?
Owner: Possible return hose o-ring failure, this allows air to be pulled into the system, and the noise is a result of cavitation in the pump, with low pressure, giving the impression of no assist. ( A lot of power steering pumps are sold to correct this issue, and that is not necessary ).
Owner: Turn signals or Four Way Flashers ?, sounds like the Flasher Unit has Failed.
