Suburban Won't Start - Mechanic can't figure it out

15

Asked by Mar 27, 2011 at 08:21 PM about the 1997 Chevrolet Suburban K1500 4WD

Question type: Maintenance & Repair

Hello, I have a suburban that won't start. We replaced the fuel pump and filter in November (OEM Parts) and it ran fine until yesterday. The mechanic replaced the crankshaft position sensor, camshaft position sensor, fuel pressure regulator and it still won't start. We have a P1345 code. Can anyone help with what this might be? We've spent so much money now and were not any closer.
Thank you

Can't diagnose much from a distance, but if the crank sensor wasn't recalibrated properly with the GM software, it won't start, i'd make sure it was properly recalibrated b/c p1345 means crank sensor error.

Thank you so much for your response! I don't know if the crank sensor was recalibrated. How or where would I have that done? We just replaced it today, does it not come calibrated? We purchased the part at autozone. Also, we had the p1345 error before we replaced it by the way. Thank you again, I appreciate the help

To answer your question, no they do not come calibrated. You need at least a GM TechII tool to recalibrate the sensor. If that is truly the problem, put it on a trailer and the dealer will do it for under $100. Are you getting the required fuel pressure of at least 55 PSI at the fuel rail? Go back to autozone and ask to rent their fuel pressure test tool, screw it onto the schrader (bike tire type) test port on the fuel rail and turn the ignition to run and try to start it.

I am having similar prob w/my '97 Burb. Just wondering if there are any success stories to share.
