2006 CTS crank no start troubleshoot and fix 

Thx for the video mines came without instructions but you cleared it up by showing the wiring pattern

Just helped neighbor with same problem.. He tried to Loosen the ring for a week before he called me. He was hitting it with chisel.... I told him the Auto Parts store will lend you a tool, Off he went. It DID NOT fit just like your first tool.... so I grabbed a huge set of channel lock pliers and a 1 Ft long 3/4" steel rod to use as punch. I hit the Rod with the hammer and it move and then just moved back. So I had him squeeze ring from the opposite side like he trying to move it, while I hit the other side with the punch. The ring moved and did NOT move back, three or so hits later the RING WAS OFF. We had to put it back on the same way. Hope this helps someone. He did the CUT the floorboard method also......Vegas OBie

Cadillac CTS 2007 Will start but dies out right away after 2 seconds. All I did was install new coils and new spark plugs. YESTERDAY Before Id di this the Car ran smooth with a little mis-fire. I chose to replace all the coils and plugs. NOW I get a startup then the 2 seconds shut off?? I checked all the fuses and they seem to work? What can I do now?

Were can I get the picture of the wire's my pump came with no instructions

With any GM vehicle including my '03 CTS I can always hear the fuel pump turn on briefly to prime the line when I turn the key on but do not go to crank. The engine computer must be powered down between attempts as it will not prime the line a 2nd time if the computer did not shut down. A fuel line pressure gauge does not cost much and is easier than pulling fuel line off the filter. The first time or few times the fuel pump fails to run you may coax it into turning on by tapping the fuel tank from underneath so motor will move just a little so it will start running so you can get home. Sooner or later this will not work. You need to put downward pressure on the pump to twist the ring on or off due to pressure of o-ring pushing up and keeping the ring locked. Put a wood block on the pump on flat area and have your assistant step on the block. Then a hammer and bar can be used to spin it off. Another channel showed that a relay my click but may be defective. Their defective relay did not sound the same as a good relay when each clicked. One can swap relay or temporarily run a jumper wire across it while diagnosing the issue. I used a cutting wheel on a Dremel. One has to be very careful to not cut into the plastic fuel tank just below the steel.

What if the car doesn’t start with starter fluid

Do u know the guy from polar bear comedy ? U look like cousins great video btw helped slot

What a pain in the a** that job is… lol .. I’ll be diagnosing mine this week.. praying it’s just the filter.. but probably not.. oh well..

So what if it only cranks but I have smoke coming from the exhaust?
