i just got my car done and i tried to start it but it wont start
do you think it should start with no tune?? my cam is 306ish and i have 30# injectors that arent tuned for

 

What exactly happens when you try to start the car? You'll definitely need tuning on the car...

 

i know i need tuning but i got a little impatient and wanted to hear it for a second. when it was turning over it sounded perfectly normal. but but it wasent even trying to start its like all the plug wires are disconected. do you think it should atleast try to start with no tuning?

Did you make sure the Opti was installed rite? That little tab on the Camshaft has to go into the "odd" hole out of the three on the end of the Opti. Also, when you installed the Opti, did it basically slid rite into place, or did you have to tighten the bolts to get it in all the way? If you had to tighten the bolts, its possible that the tab on the camshaft didn't go in the hole ( Off center of where it should be ) in which case, your probly would have done damage to the Opti.

Did you put the coil wire back on? I know its a dumb ? but a few times on this board, guys have come back from doing a mod, saying it wouldnt even try to start, and then realize they forgot the coil wire.

To check the Opti, try this, unhook the intake elbow, and spray a VERY small amount of starting fluid into the intake, Crank it and if it sputters, then your definatly getting spark.

Are you sure the timing marks were aligned properly?

Did you tighten the rockers too tight? Dont go more then 1/4 turn past ...

Were the 30 lbs injectors brand new or used? If theyre used, they may all be clogged. When I rebuit my car ( Got it totalled, and put it all back together) all 8 of the injectors were completely clogged, would not spray even a single drop, so I soaked them in the nasty **** my Dad's boss had and it cleaned them all up fine. It idles perfectly smoothe now. ( O yea, to check if theyre clogged, youll need another person, Unblot the fuel rails, lift then up a little bit, and have someone hold them while you go crank it real quick. They should each spray a small uniform misty cone of fuel ) and when ( if ) you have them out, be sure to not get any dirt/grease down in the holes the injectors go into. If they need soaked in something to clean them, Be sure to take the O-rings off of them, and make sure that you keep the top injector orings from the bottom ones, if you mix them up, youll have a leak.

Go over everything, Make sure all your plugs/wires are in tight, check the intake, the O2's, everything. Check the grounds too.

It SHOULD at least try to start. To TRY starting, all an engine needs is a minimal amount of fuel, air, and spark. Its for sure getting air, so check for spark with JUST A TINY BIT of starting fluid ( Have a hose close in case it backfires the starting fluid ... , easiest way to spray the starting fluid in is to disconnect the elbow, open the butterflys, spray a VERY SMALL amount in, and have someone crank it when you tell them too.) If it starts to try with starting fluid, then its not getting fuel ( Most likely) and your problem would be them 30 lbs'ers ... If it still doesnt try, then your not getting spark.

Get a tune for it ASAP too ...

 

i put the cam dowel in the slot on the opti next to the one i think, its kinda hard cause once you get to a certain point you cant see behind the opti anymore, but i lined it up the best i could and it slid on with no problems. one worry i have with my opti is that when i took my water pump off alot of water came out amd could have got the opti. ill check that with some starting fluid and i have a spark tester

i checked the coil and its pluged in

i adjusted my valves 1/4 turn past 0 lash. i used methot three on shoe box's site

the timing mark on the cam sprocket is on the bottom and the one on the crank is on the top and there aligned perfectly. im 99% sure it was on tdc# 1 when i did it

my injectors are new

ill go over everything again tomarow and see if i cant find the problem. i thought it would atleast try to start to

thanks for the reply

 

Yea ... it should at least try a little bit or something. Let us know how it is once you try a little spray of starting fluid. It should at least try a little, and sounds like its timed rite, the Opti was put on rite so ... I dont think it would ruin it if it got some water on it but you cleaned it up rite away, I could be wrong though ???

As for you taking them 1/4 past 0 lash, try backing them off a little bit. There was a guy on here a while back that tried everything, and it ended up that 1/4 turn was too much and it wouldnt run. Theyre a touchy thing to get adjusted rite ...

 

are you sure youre getting spark? Id also pull a few plugs and make sure its not already fludded. you should go over all the conn.s and grounds on the engine. also, make sure you have power to the inj.s on one of the two wires , and flickering ground on the other wire while the eng. is cranking. OR, you could unplug the coil (to kill the spark), lift one side of the fuel rail out so you can see the nozzles while someone else is cranking. this will obviously spray fuel (hopefully still into the hole in the intake for the fuel inj.) so be ready to clean this up if need be. try to do the rocker adj. thing. just take ea. rocker nut and back it off 1/4 turn. no need to go through the hole process yet at this point. if this makes it better (tries to start maybe) then maybe go through and relash them to zero lash.

Im act. goin through the exact same thing on a mustake that Im helping a friend build.

ok i put a spark tester on the # 1 plug and it has absulutly no spark and i know the tester is workin caus i tried it on my girl friends car and it works fine.

so do you guys think its a bad opti or what?
even if it was a bad opti wouldent it get alitle spark?
what else do you think could cause no spark?

 

Coil ???, Opti, Fuse ?

 

test the coil see if it is any good...
the car will run on that tuning HOWEVER it will run like ****... if you want I can email you a file to get you going....

give me a call shawn

 

How do i test the coil?? and the opti?
if it was a blown fuse wich one would cars no spark?

 

its alive!!!!!!!!!!! it was a burnt ignition fuse.
thanks for all the help guys.0
