My 2006 Grand Prix will crank but no fire to the fuel pump. I’ve installed a new pump, changed relay and checked fuses & changed the exterior fuse box but still no power. I can jump the pump at the rear and get pump to run and disconnect then try to start and car will run shortly. What do you think the problem might be? The only thing I have not changed is the crank & cam sensor and ignition switch

Thank you! As you can see this feedback page does not offer us the ability to communicate properly but the forum does.

My question is why do I not see you using a high dollar fuel pressure/volume gauge.
I am considering buying one but do not want to if it is really not necessary there is a million other tools I could use.

Hi Paul,
I have been watching your videos on YT for the past two months and I can say that YOU ARE THE BEST OF BEST. I wish you all the best. If I had lived near PA I would definitely met you in person. My background is in IT, but I love to know how to diagnose a car logically by applying science and common sense.

Thanks,
Omar

I would just like to thank you for sharing your knowledge with everyone! When I started my 2 year automotive program, I quite my job and opened a mobile mechanic business to help me get through school. I have used your knowledge along with my teachers at Wenatchee valley college to build my business from the ground up. I started with a rusty old truck and a few tools.I now have a small shop and a fully functional mobile service van. You have made my dream of owning an automotive repair business possible. Seriously thank you
