Painted intake and TPI runners and ph.Ground Prob???

I just painted my whole TPI unit along wit the intake and after everythong was put back together the car would start just cranks...has fuel in the fuel rail and I can hear the fuel pump prime and shut off after abt 10 seconds or so...tested for spark and not spark at the plugs...tested the right connector on the coil wit test light and lights up wit key on...what I'm wonderin is that when I painted the intake you painted the dizzy hold clamp and where it mounts to the intake and now it's night grounded now...does this clamp act as a griund to the intake aswell and is there suppose to be a ground from the intake to ????..i made sure everything was hooked back up nothing...nedd help plezz....thanks

Re: Painted intake and TPI runners and ph.Ground Prob???

yup marked the firewall and marked the valve cover but end up replacing valve overs but didn't do any good there....had a friend come over and check timing that's when I found out no fire to the spark plugs...checked fuses and everything...just now got done sandin the clamp and intake mounting part so if it's true would get a ground....so how would I go abt check to see if the dizzy is getting power...???....92 camaro 305TPI

Re: Painted intake and TPI runners and ph.Ground Prob???

What electrical connections did you remove when I did mine the first time I didnt plug my conections in the right spot, Go over your ignition connections and make sure they are pluged in to the right spot I moved a connection to another spot I know for a fact its interchangable with another Im sorry i cant be more exact its been along time but i had no spark at the plugs either my old man came over and took him 1 min to figure it out and it started right up

I been thinking it might be that but really don't see how it would be good one day then change intake gaskets and then it goes bad..it was running fine before intake gasket change and valve cover gasket change..i even jacked it up and changed out the oil press sensor by the oil filter.only plugs I messed wit was the two coil connectors,dizzy connectors and manifold temp sensor which I checked out to make sure I didn't mix them up and what I can see their is no way of mixing them up.i hooked up a text light and turned the key on and prode the dizzy connectors and nothing...so I'll just take the icm off and have it tested when I get off at 2 tomorr....hopein it's just that..this car is really breakin me..should have just kept my 2 irocs..damn girls..lol

Re: Painted intake and TPI runners and ph.Ground Prob???

Although my IROC is totally modified and some things have been moved around. I have grounds on both cylinder heads on the back side between the fire wall and the heads. Did you check those? Also my intake is painted and I never had problems with it not grounding properly. Also did you check your coil, I've gone through several of those, one time it happen when I was re-installing my engine, and it took along time to figure that one out.

The stock replacement MSD coils are junk and made in China, if thats what you have! I went through 3 of them in about a 8 month time frame before someone on the board told me about that after I posted about no spark issues. I then replaced it with the higher end MSD coil that I believe is made in the USA, and I have not had any problems since. Also when you are you referring to ICM, do you mean ECM? If thats the case I'll have to keep that in mind as I didn't know they could do that.
Thanks for the comments on my IROC as well, I've been working on the car for 10 years now, and still not done/satisfied.

Re: Painted intake and TPI runners and ph.Ground Prob???

I tested the old module and tested bad so got a new one and poped it in and still not spark......Anything else I could check??? It would always show a spark doing the plug wire test right even if the timmin is off now right????cause I might have put the dizzy in the wrong place when I returned wit new ignition module.

I know you said that you checked the coil out, but if you have the coil of the following link; http://www.msdignition.com/Products/...reet_Fire.aspx you may want to consider replacing it with the better coil of this following link:http://www.msdignition.com/Products/...ctor_Coil.aspx I don't think its necessary to pull the plenum and runners off. Everything that could cause a no spark condition should be easy enough to access. A couple of things I found to help trouble shoot the problem. Is get a timing light and connect to #1. Have someone crank the engine over if you can't reach and at the same time check for the timing light to flash. The light flash should be at the normal brightness. If the light is a weak flash, no flash, or random/occasional flash then it could be your coil is going bad/or is bad. You can also put the light on the coil wire and do the same thing. Another thing is check your fuel pump relay which is usually located on the drivers side firewall. Easy way to check this is when you turn the ignition to on but not start/crank the first couple of seconds you will hear the fuel pump activate. If your not sure crawl underneath by the tank and have someone turn the ignition to just on only. It also takes the ECM about 30 seconds to reset before you can do this again. During the first couple of seconds of ignition on the ECM is checking different things including the fuel pump. If it detects something wrong it won't allow spark to occur, and you will just be cranking the engine over.

I order the other MSD coil you was talkin abt and took the one I had back...my fuel pump comes on wit the key turned on...i know I need to hook up a couple of vacuum lines up that's why I was gonna take the runners off so I can redo the lines..another ? Do I need that weird lookin connector that a duel vacuum connector hooks in to..its mounted wit the MSD on the same bracket.it even has a eleri connecto pluged into it as well

Glad to hear you got it fixed! I actually forgot about a distributor issue I had last summer which involves a race. I was coming back from a starter/alternator company and I was in my IROC. It was late evening, and the traffic was light. When a late 90's Mustang Gt slides up along the side of me. The car looked pretty good red in color, and as he rolled a little a head of me I could tell he had aftermarket exhaust and was using racing racing fuel. We then stopped at the next light and we were both lined up. We both looked at each other and he gave me thumbs up, and then asked if it was on, I could not resist the temptation and gladly excepted. The light turned green we rolled through the intersection at a normal pace. Once it looked clear and good to go, he honked 3 times, and from about 20 mph it was on and I spanked him by 4-5 car lengths and I was still pulling when he gave up and flashed his lights which i saw in my rear view mirror. We then cruised to the next light which was red, and he gave me thumbs up again and smiled. Then he asked if I wanted another go at it at about 45 mph roll, I said sure! So once the light turned green and we had clear/open road. He honked 3 times and I started to pull on him immediately, but then I felt the car stutter a little. Then it seemed to get really sluggish, and then my engine died. He of course blew right by me, and kept on going as I was just coasting to a stop. Any how after about 2 weeks of trouble shooting, it turns out the spring in my dizzy cap was the problem as it just gave up.

That's funny I would have been mad as hell...I haven't been doing any racing in this camaro I have.only has a 305 but does have a cam and headers flowmasters...now when I had my 87 iroc wit the 350 vortec cammed out and everything else you can think of I would race mustang's,rice burners and I would beat tha **** out of them..that's the iroc I been tryna get back for 2 years now.looks just like urs same color and all..I been puttin a lot of money in this camaro like crazy since November..I have a 02 camaro ss LS1 engine and trans that I got for the iroc I sold that I still have..savin it for another red iroc or my old iroc if I get it back...I had a nice 89 iroc too but sold it back in January....
