Hi there! My name is Mike. The site will be promoting a call.I will let you know if it's necessary

Ask Your Own Car Question

There are a few fuses to check. Start with the fuse in the fuse box under the hood labeled BCM3.

Inside the car you want to look at the fuses numbered 10 and 16.

Check these out and let me know.

Please let me know if there is anything else I can do to help and earn a 5 star rating from you.

That is AUX B

What size engine do you have in the car? Maybe that's a factor here.

Can you upload a pic of the legend on the cover of the box?

Ask Your Own Car Question
Customer reply replied 1 month ago
where do I send it

You should have a paperclip icon on the tool bar, you can use that to upload the file.

Also, please let me know the engine size.

Thanks

Ask Your Own Car Question
Customer reply replied 1 month ago
Engine size is a 3.8

I am not showing this model yr with a 3.8L V6, can you double check the model for me?

Ask Your Own Car Question
Customer reply replied 1 month ago
that is it 3.8 L V6 it was running good I drove it home and parked it cut it off in about an hour later try to crank it it would not ruin it cranks

I am going to open this question back up for the other experts.

I am not sure, but I am not finding a cobalt with the V6 for this year, so it's got to be a different model or a different year. Of course this would completely explain the fuse boxes looking different.

Good luck to you with this.

Please don't post a reply to me or rate this or the other experts won't see it.

Hey Roy this is Joseph about a month ago I put a brand new fuel pump and brand new fuel filter on this car it was running good yesterday morning I drove it home part in the yard went back out to start hit a cranks but will not run I checked the fire on the injectors I checked the firing for the crankshaft sensors I checked the fire on the spark plug it showing that it has fuel in the rails I push the valve in and feel will shoot out the rails but it just will not run this is a 1999 Pontiac Grand Prix 3.8 L V6
it has the fire at the place in it need to run but it will not run just crank
hepl

did you check and see if the wire back to the PCM from the injectors is flashing with a test light to indicate it is being commanded to allow fuel into the cylinder??

try spraying some starting fluid into the air filter and see if it starts and stalls out.

Roy

Ask Your Own Car Question
Customer reply replied 1 month ago
sir I sure did and I spray some starting fluid in it but it still will not bust off that's what got me confused about it it was not making any noise as though I was having timing chain problem
its a hard one for me

does the tach move up a little on the dash when you crank the engine??

can you do a compression test to be sure it is not the timing chain??

Roy

Ask Your Own Car Question
Customer reply replied 1 month ago
the tach moves up a little bit on the dash it Act if it trying to bust off I also put a temperature sensor in it as well
????

ok, then there is a signal from the crank sensor to the PCM>

back to compression. can you test the compression??

Roy

Ask Your Own Car Question
Customer reply replied 1 month ago
