I need help! Very badly. I cranked the car today and it had a very raw fuel smell. I then started checking plugs on fireing and notice that the whole drivers side on all the cylenders isn't fireing. Any idea of what to do next?

Well maybe start with the fuses.
Fuses #40-47 have a lot of the engine stuff.
Then look for wear on the wiring harness.

 

Double check the obvious- look for stuff that isn't plugged in, etc. Also, use your tuner to check for trouble codes on the computer.

 

rev the engine all the way up and hold your foot un the pedal for a while mins...wait thats how to race someone in an auto.

Check the spark plug wires

 

These motors still have spark plugs?

 

Stock and slightly modded yes. Serious mods require a flux capacitor to spark in the chambers...

 

Thats not funny. Give the guy some good advice or don't post at all! Don't rev your motor when the engine is misfiring. With only one side of you engine firing it is out of balance when running if you stress the motor in this state you will damage it. If your car is still under warranty take it in. If not try to check the simple things first like your wiring harness fitting on that bank of cylinders and fuses. If that doesn't work I would take it in. As nice as your car is in the picture spending a little money on it to keep it running right is not a bad thing.

 

Just installed Comp cams stage 4,ARH LT's and gt500 fuel pump, car was running fine before install.

 

Are you absolutely sure you have the cams phased correctly? That is the most important thing when putting cams in one of these motors. If not phased correctly that entire bank of cylinders will be out of time. I would check for things that are unplugged first...check the cam timing second. Do not run the motor anymore until you are sure.

Any update on this? Was the cam phased correctly?

 

Will be working on it tomarrow, I'll post an up-date after that. I've been told that we might just have a wire pinched or maybe a ground off, I let everyone know what we find out or if we get it fixed ,what was wrong.I appreciate the people that are trying to help,but also at the same time I asked for help with a very serious problem and I didn't need the bs comments. any time someone has asked me for help with a problem, I'm there with the answer if I know what to do.I don't give the smart *** comments, instead I try my best to help out.For those who were trying to be a smart butt, I'll remember you , when you need help. But for the others I'll be there to help.

 

Is this the initial crank up after the cams install..?? If it ran OK after the install for any time, I'd say it's probably not cam timing... Which would be GOOD... Unless something was left loose or has broken in the timing system since the install.

I would think the plugs would fire even if the cams are out of phase, but with these computers, they might not.

Hope it's something simple.

your dealer won't touch here after those mods. If not the cam check your fuel injectors to see if the free of debris...

 

Hey Bobby,
You might re-read his initial post. I think it happened on first crank up after the cam install. At least that is the way I read it. For his sake I hope he finds a pinched wire or something unplugged.

Thanks for the honest concern! yes it was the first cranking of the car since the cams ,ARH LT's and gt500 fuel pumps install.Car cranked and ran but it had a very raw fuel smell! notice it wasn't firing on all four of the drivers side cylinders. My machanic is going to be working on it tomarrow, hopefully, he'll find the problem. I'll let everyone know what happens.
even though it was running on four cylinders, this exhaust is very load, can't wait to get it running right ,so I can post video of the sound.

 

James, I think most of the 'smart' responses were due to the fact that you did not say anything about the major install that you just did. If you read your initial post, all it said was the engine was only firing on one side. You didn't say anything about cams, fuel pumps, LT's, or anything else modification wise. Since this was the first start since the major install, that would have been a big big BIG clue to everyone as to why it was running the way it was.

I was about to suggest calling your dealer too until you told us about the cams installation the next day. People assume your car is stock unless you tell us otherwise.

 

No problem! I'm just flustraited! I should have explained the problem more. Well I think it's out of time on the drivers side bank. We have the motor back down to the timing chains, going to make sure it is timed right.starting on it in the morning. wish me luck.

 

Well she's fixed! the LH bank was out of time by 180 degrees. CAUTION: when doing the cams installation to get the right diagram on which marks to use on the RH and LH cams sprocket, you need to use the timing PDF file,it shows the right diagram on doing the correct timing.The cams and valve springs PDF file is very confussing on the timing marks. Make sure to use the l mark on the RH side and the L mark on the LH side.

I'll post video and pictures later today or tomarrow, I'm re-doing a bath room,Floor,tub and sink now.

 

Good news, show us some remodel photos too!
