kklinger Posted February 18, 2005 Report Share Posted February 18, 2005 My cadillac was running fine until Monday morning when it wouldn't start. Turns over and lights, radio, etc. work. Checked fuses, cleaned cables, and fuel pump kicks on. No new codes. Had the plugs and wires replaced by local mechanic about 6 weeks ago. Any suggestions would be appreciated. Thanks.

adallak Posted February 18, 2005 Report Share Posted February 18, 2005 It may be neutral safety switch. Try to start in Neutral. If it starts I'll explain to you how to fix it. The saddest thing in life is wasted talent Link to comment Share on other sites More sharing options...

Have you determined if you are getting spark and fuel? I would connect a fuel pressure gauge and check for fuel pressure. Your fuel pump could be running but not producing pressure. And check for spark at each coil. Do not pull the wire out of the coil and let the sparks fly around you can damage sensitive sensors and electronics with a well placed zap.. See if you can find an Ignition Spark Tool, like one of these that will do the job.. Mike http://www.mytoolstore.com/toolaid/diagn03.html Link to comment Share on other sites More sharing options...
kklinger Posted February 20, 2005 Author Report Share Posted February 20, 2005 Has spark but they aren't wet with gas after trying to start. Any links to how to check fuel pressure? Thanks. Link to comment Share on other sites More sharing options...
PAUL T Posted February 20, 2005 Report Share Posted February 20, 2005 Check the fuel pressure regulator(FPR), pull the vacuum hose off, if it has one, and have someone turn the key on to pressurize the fuel system. If gas come out the vacuum nipple then change your FPR. Link to comment Share on other sites More sharing options...
Scotty Posted February 20, 2005 Report Share Posted February 20, 2005 You can purchase a fuel pressure guage and attach it to the schrader valve on the fuel rail.... The guages are not too expensive and are a good addition to your tool box.. Mike Link to comment Share on other sites More sharing options...
kklinger Posted February 21, 2005 Author Report Share Posted February 21, 2005 I will pick up a fuel pressure guage and fuel filter tomorrow. Is the fuel filter on a 96 Deville between the driver's door and back tire? Thanks. Link to comment Share on other sites More sharing options...

Is the fuel filter on a 96 Deville between the driver's door and back tire? Thanks. I think its between the front door and the front wheel inside the frame rail, but I will look at my 96 manual and post a photo of its location. Its outside in the garage right now, Mike Link to comment Share on other sites More sharing options...
kklinger Posted February 23, 2005 Author Report Share Posted February 23, 2005 Checked the FPR, it doesn't leak. Put a fuel pressure guage on and NO fuel pressure. I'm not sure if the fuel pump is kicking on when I turn the key, I thought it was but now I'm not sure. It does click. Funny thing happened when it was trying to turn over, one time the hood popped open and another time the gas door popped open. Any thought????

Scotty Posted February 23, 2005 Report Share Posted February 23, 2005 Try cleaning your battery cables it sounds like you have having battery connection problems with the trunk and gas cover popping open. Find and check your fuel pump relay. Link to comment Share on other sites More sharing options...
Ranger Posted February 23, 2005 Report Share Posted February 23, 2005 If you have zero fuel pressure, the pump is not running. Have someone turn the key ON while you have an ear to the open fuel filler pipe. It should run for 2-3 seconds and you should be able to hear it IF it is running.
