Will not start

Check your fuel pressure make sure it's within specs and comeback and give me the readings.

This question was prev. Asked by someone else. I have the same problem. Prev. Answer said to check fuel pressure & get back to him. How do I check the fuel pressure?

You need a fuel pressure tester, hook it up on the fuel rail test port turn key to run and record pressure then start car record the running pressure

2004 Grand Prix was running fine until one day no crank no start just click.I check the battery, battery was good 12.4 volts I went out a few days later to mess with the car and it fired right up so I shut it down try it again same thing no crank no start. So I figured it was the starter pulled the starter checked it with a set of jumper cables appendix would pop out but no spin so I replaced the starter same thing no crank no start just click. So at this point I removed the crank relay and put a jumper wire from K4 to m5. Same thing no crank no start just click

I previously asked this question, and I tackled the project my self and looked up on the internet how to clean your throttle body in your car and honestly it is very simple even for someone like me who had no idea a throttle body even existed, just look it up (I used the Mobil directions). I cleaned it out and now my car runs like brand new. I hope this works for you. Also if it does work I suggest using the STP GumOut additive to your gas tank to prevent build up again in the engine.

Clean them up and snuged them back down did the same thing I left the key on this time in the car's computer read charging system failure any ideas on what this could be?? The ground clamp terminal is a funky set up and doesn't look like its getting a good connection so I put some vice grips on it tightened it back down same thing.

Electrical problem
2004 Pontiac Grand Prix 6 cyl Two Wheel Drive Automatic

I have a 2004 pontiac grand prix. The problem started 2 days ago. It started after I had coolant put into my car because the coolant light was getting coming on and the car was starting to run hotter than usual. Afterwards as I was driving home I hit a big puddle, due to excessive rain. Since then I have been having trouble starting up the car. The battery is fully charged and has been checked. But when I get in the car and insert the key into the ignition the power system seems fine, but when I go to crank the car up everything dies on me. I'm not sure what could be causing this issue.

My car is locking on its own. Lights going on etc. And when I start it it idles hard and when I step on the gas it takes a while for it to kick in. Like fuels not getting to it properly? Lags when I first start up and when I step on the gas. Could this be fuel pump or computer since its messing with electrical things as well?

I have a 2004 Grand Prix GT 3.8 V6 auto trans. First thing in the morning it starts fine. I can drive across town shut it off and try to restart it immediately and it wont start. All electronics on dash and radio will all come on but when I turn the ignition its like there is no connection at all. No clicking of the starter or anything. After it sits for 2 or 3 hrs I can go out and it will turn over but wont start right away. After I try to start it a couple of times I can stop for a couple of minutes and then it will start right up. I can drive it back home, park it and go through the exact same thing again. It is very consistant and will do the same thing every time. Have not tried anything yet except jumper cables just to make sure it wasnt battery problem. Any ideas will help.

Hi there im new to this website and I would like to know what I am doing wrong. I have found the 12V constant for the push button and I also found the starter wire but when I wire it all up and put the key in on position and push the button the car does not start. However when I turn the key hold it there while pressing the button the car starts. What can I do to just be able to push the button which is what I bought it for. Pls respond any solutions thank you vry much- alxer

Where is the location of the starter solenoid on a 2004 grand prix

I would also like to add that my grand prix has a pass-key 3 system will ur solution still work?

When I attempt to start my vehicle it seems to start fine but then immediatley idles all the way down and dies. If I press the accelerator while starting I can "fight through" the reduction in RPM and the vehicle runs great from then on. Never stalls or misses once it's running.
