Installed New Plugs and Wires. Now it won't start?
The car was running fine yesterday morning before I decided to install new spark plugs and wires. I installed new AC Delco Platinum plugs and Street Fire wires. The wires were cut to fit, crimped, and installed. Now the car turns over but won't start. All of the plugs are in tight, the boots are on the plugs tight, and the plugs are on the distributor tight. I have checked and rechecked all the connections and can't figure it out? I'm sure it is something simple that I can't find, but maybe with some experienced help I can. Any help would be appreciated.

Re: Installed New Plugs and Wires. Now it won't start?
Is there Spark ??
If there's spark thru each plug wire then the problem is elsewhere; start checking for fuel !
If there's no spark; start checking at the power wire to distrib,.... then to the module, then to the coil, then from the coil, then to each wire.

Did you route them wrong 18436572 order
Did you start with #1 in the correct location on the cap

Re: Installed New Plugs and Wires. Now it won't start?
I've checked the spark. I have spark at each plug through the wires. I have fuel and my fuel pump is priming. I have no idea what the problem is now. It is turning over, has spark and fuel, but won't start.

When you start the car do it turn over fast? If so then look at the wire for the coil. It is possible that it came off the coil.

Re: Installed New Plugs and Wires. Now it won't start?
It is turning over a little slower than normal. I have checked the coil wire connection. I will do a search on how to test it. I do have a multimeter. Thanks for all the help so far guys. I need to get runnin for tomorrow.

I wonder if the distributor got turned a little while you were working on it ??? Could have knocked off the timing,........ setting it to factory specs only takes 10-15 minutes and might be worth checking. Make sure that the Battery has a real good charge on it too !!

Re: Installed New Plugs and Wires. Now it won't start?
When replacing plugs and wires you've got to identify which plug wire is number one. Someones had the distributor out and dropped it in with number one in a different location.
1st : Make Sure The Wires Going To The Distributor Module Are In Good .. If so
2nd : Pull #1 Spark Plug Out, Bring It Up On Compression Stroke, Align The Timing Marks, Remove The Distributor Cap and See Where The Rotors Pointing. Thats Your #1.

Re: Installed New Plugs and Wires. Now it won't start?
Good catch. I've had that happen on a newly purchased vehicle. Although, it'll usually fart up the intake pretty good if it's that far out.

Re: Installed New Plugs and Wires. Now it won't start?
Did you pull the distrib ??
The Rotor doesn't appear to be @ #1 right now. Should be pointing almost straight forward with only a slight point to the drivers side when marks on balancer and timing tag are lined up.
The distributor appears to be turned a bit to far,... Needs to be turned clockwise and have plug wires re-set to compinsate ??

I'm at the point where I'm about to get a new MSD distributor and 6AL. But i'm afraid of getting the goods and still not having it fire.

its only $98 buck to have a tech at your local pepboys take a look at it. id say let them figure it out before you dump a grand into it.

Did you check the fuses under the dash to make sure they was not blown?

Doesnt the rotor just slide down on the shaft since its grooved? Hard to mess that up.

Re: Installed New Plugs and Wires. Now it won't start?
So now it is about to be towed back home so I can change those parts out. Definitely not paying $1018 to have it fixed. Now the only questions are to which fuel pump and replacement starters are the best.

Re: Installed New Plugs and Wires. Now it won't start?
sounds weird but check the diagnosis. spray starting fluid in the intake to make sure that the car is getting a start with another fuel source. if so then you have got your second opinion. as for fuel pumps, everyone kind of has their favorite but if i get any electronic equipment i always go to either napa or the dealer and make sure to keep the reciept in the glove box for warrenty if needed. as for the starter, id look to find a shop in town that rebuilds them. when you find the shop you will never forget where they are located because of the price savings and the fact that they will most likely rebuild alternators also.

Re: Installed New Plugs and Wires. Now it won't start?
before you buy a pump and a starter. Go rent a fuel pressure tester from autozone or Kragen. Check your ground straps from the neg battery terminal down to the chassis, from the chassis to the block, from the fire wall behind the distributor closer to the factory ac to the block.
The fuel pressure tester hooks right up to the fuel rail and, takes 2 minutes to determine if pressure is sufficient. If for some reason, the ground from the chassis to the block isn't connected, the starter won't catch ground and, not spin at all or, have a very weak circuit.
The only reason I say to do this is because, Pep Boys pulled a fast one on my Girlfriend when I was out of town. Told her it was a fuel pump she paid, it didn't work. Told her it was the starter paid, didn't work, told her it was the distributor paid, didn't work. I came home towed to the house put, a fuel filter on it for 15 bucks, fired right up. They wouldn't budge on a refund or, partial refund. It was hard enough getting a sorry out of them.

Re: Installed New Plugs and Wires. Now it won't start?
s##t does happen. do make sure that if you dont get the car started with starting fluid to let me know i used to work at a shop and know how to get them to rediagnose for free in most cases. as for them not getting you your money back hilltop530, just call corprate. the last thing any shop likes is a mad customer.

Re: Installed New Plugs and Wires. Now it won't start?
I haven't ordered any parts yet. I sprayed starting fluid into the throttle body while a friend turned the engine over. It didnt try to run. The starter does sound rough so I will get under the car and see if the bolts are staggered or in line to order a mini starter from Summit possibly later on. The fuel pump did prime when the key was turned to the on position. I'm not sure if that means it still works or not. But I will check out a pressure tester and get the final answer. Thanks for all the help so far guys.

Re: Installed New Plugs and Wires. Now it won't start?
does the vehicle have vats. if you spray starting fluid in the intake and the vehicle didnt start then i would be willing to bet it isnt the pump. do me a favor and send me the invoice number it would be on the front of your customer copy. it is a 4 digit number followed by a 7 digit number if i remember correctly.

Re: Installed New Plugs and Wires. Now it won't start?
Alright, after I work I tested the fuel pressure at the rail. It read around high 30's to low 40's psi. So I know the fuel pump isn't dead. I ran out of time before I had to go to class. Anybody have any ideas on what to check next? I do plan on setting the timing tomorrow. Any help is much appreciated guys.

Re: Installed New Plugs and Wires. Now it won't start?
Pep boys tried to get you on that one. Well, that's one more thing checked off the list.
and you were getting fuel and spark? When you're cranking the car over, does it seem to be cranking rough? ( loud noises or chatter from anywhere)

Re: Installed New Plugs and Wires. Now it won't start?
The starter is beginning to sound rough. I have ordered a mini high torque starter from summit. It's on the way. It turns over strong but won't start. It's frustrating. It makes me want to swap in an LS1. But then I feel degraded because I can't even get this motor started. Haha

you might need to check out the ESC Module. They already have a decent thread going about it if you want to check it out.
