Hello.
I was wondering if someone might be able to help with an issue with my 2004 sunfire. The car was turned off to get gas, gas was added, went to start and it is just turning over. I had it towed back to the house. Here is what I am finding:
No spark. I first tried starting it by spraying some starting fluid in the throttle body, no start. I then took off the piece (don't know the name) that has the coil pack on the top of the motor. I tried the screwdriver method holding it close to the metal piece coming out of the other piece I don't know the name of and grounding the screwdriver to the top of the motor. No spark. I then tried hooking up an old plug wire to the piece I don't know the name of and laying the spark plug on the top of the motor, no spark. I then took the wiring harness off the coil pack. There are 5 connectors on the wiring harness. I though (and maybe incorrectly so) that 4 of the connectors should light up as I crank the motor. I checked all of them with a test light (with the other end clipped to the battery ground) and only one would light up.
No fuel. While cranking I opened up the shrader (shroeder, sp?) valve. No fuel came out. I don't hear the fuel pump run at all when I first turn the key on. I then went to the fuse box in the engine compartment. I checked the fuel pump relay sockets and found the following.
pin 87 is always hot as I expected because the internet never lies...
ping 86 is ground as expected.
ping 85 is suppose to light up for a few seconds when you first turn the key on, I get a short blink, like really just a blink.
I jumped pin 87 to pin 30 to try and get the fuel pump to run, nothing.
I unhooked the battery for about an hour because I read about a "relearn" process and since I am stumped, I tried it. I was surprise that when I hooked the battery back up, the car cranked over for about a second. After about 5 seconds, it cranked again for about a second, it did this one more time. The key was in my pocket... That did not help, same no-start issue.
theft system: I read a lot about the theft system. I never knew it had one and I am sure I don't understand how it is supposed to work. However, I read about following a procedure where you crank for 2 seconds, let it sit until the theft light goes out, turn the key off, then do the same procedure two more times. I tried the procedure and after the first crank and letting the key stay on, the theft light never goes out. I let it sit for about 30 minutes and the theft system light is still on. I tried this a couple of different times and always the same results.
I checked all the fuses with a test light. All good EXCEPT in the fuse box in the engine compartment. In that fuse box there is a set of relays, a set of large fuses, and a set of small fuses. ALL of the small fuses do not show power. All of the large fuses do.
Also, the gas gauge does not work. I put in size gallons of gas and my son claims to have put in 10 bucks worth when the problem happened so I am guessing maybe close to a half tank total should be in there.
If you made it this far, thanks. I appreciate it.
