You should have an IAC. It is located on the throttle body on the passenger side. It has 4 wires going to it. If you need a pic let me know. Guy

I'll be coming but the ZX wont be. Pulling the engine back out tonight! This is a good thing! This means the body/paint work is just around the corner!(late october-november ) God I cant wait to have my car painted, Im so sick of looking at the 24 year old paint! Not sure what I will bring but I'll try to find something? Hey should I bring my Gtech Pro Comp? Anybody interested in their 1/4 mile times? I know the HP/TQ feature isnt really that great. Its all over the place for me. One run I have like 225HP/300TQ the next run I will have 380HP/446TQ. So I dont really trust those numbers at all but eh 1/4 mile time seems to be close to what I should be running? Guy

Since spammers can get email address through posts(I have heard this anyways) I have not been posting my email address in my posts but my email address listed under my name(the email button) is correct. Does the motor run at all now? If so does it just idle rough or does it stall out? Now what kind of pressure are you getting at the rail? You should have about 45-50psi. Mine runs at 47psi.FUEL SYSTEM PRESSURE Now you may have fouled your plugs from all those times trying to start it. Make sure they are good and clean before you get too far into diagnosing anything else. It is impossible to install the 95' optispark wrong. It is keyed so you cant screw it up. Now you could have wires crossed. Heres a pic of the firing order... You could also make sure all your injectors are internally ok as far as wiring. For injectors that are shorted internally. Compare injector resistance to one another. Injector resistance should be within 1.0 ohm of each other. I beleieve they are about 14 ohms. Make sure your IAC motor is ok too. Guy

WOW nice car man! Love the flares, color, and those CCW'S Mike you are doing my dream job.....having someone pay me to build their dream car Guy

Ok heres a few things you should check.... Connector A on PCM... *Grounds at A18 & A2 good? Connector B on PCM..... *Battery+ @ B15 *Ignition Feed +12V key on @ B30 Connector C on PCM...... * Ground @ C32 Connector D on PCM..... *D1 Engine Ground *D3 Ignition Feed +12V key on These were all suggested as a possible "cranks but does not start" possible causes by ALLDATA. Especially the connector A because that is where your injector controll circuits are wired to. Now your fuel pump should turn on when cranking. I can not find the Oil pressure sensor wired into the PCM either. However I think once the engine starts to crank it switchs from the Fuel Pump relay to the 12V beingn supplied through the oil pressure switch. The switch will not close until there is 4 PSI on it. Heres what I suggest doing. Apply +12V to the #87 pin on the fuel pump relay. This is how the wiring diagram shows it. This will bypass the relay and act as if the oil pressure switch is closed. Guy PS not getting to frusterated yet are you!

If you do not have oil pressure sensor/switch hooked up this could be your problem. After the initial 2 seconds that the fuel pump is on the computer will only turn on the fuel pump & maybe the injectors also if the computer "sees" 4psi from that sensor. Let me see what I can dig up on as far as a wiring diagram.... Guy

Yeah I found that out tonight RacerX. Man this stuff seals great but damnnnnnnn is it hard to remove! I tried carb clean.......that just made it sticky and gooey.....then I tried paint thinner......same results. I think I will just have to continue scrapping it off and then use some kind of abrasive pad on my angle grinder(samll one with a 2" disc). Im just glad I only used a small amount of it! Guy

Man last time I looked at your site all I saw was pics of a rusty Z......but now! Nice work man! Keep it up! 8) Guy

Sweet now I wont have to trade with anyone! So what should we bring as far as food & beverages? Guy

Any idea yet what day it will be? Guy

Ok I take that back feed power, on the oil pressure sending unit connector, to the gray wire. That should turn on your fuel pump. Guy

Ok so you are getting power at the injectors. (check with a volt meter or test light) You should have power at the pink wires on the injector harnesses. Make sure your oil pressure sensor is hooked up and working. The PCM will run the pump for 2 seconds then if there is not atleast 4 psi of pressure on that switch or if the switch is bad it will not turn on the fuel pump. If your not sure if your oil pressure sensor is ok then just jump I beleive the orange and the black wire. There is only 3 wires there. Just jumper 2 of the till you hear your pump turn on. Then try to start the car. Also make sure your fuel pump is running when you are cranking the engine over. More and more I am leaning towards the oil pressure switch/sensor. Guy

Well I dont know if this will apply to you but I have "flashed" aka reprogrammed PCMs at work and sometimes the program doesnt get fully downloaded and the vehicle will not run because the programming is not complete. You could try downloading it again? (or have you already tried this?) Can you watch the sensors with Tunercat hooked up the DLC? Kind of like a scanner? Guy

Now when you used TunerCat to change stuff in you PCM you didnt mess with the injector settings, did you? I am not familiar with TunerCat because I cant use it on my LT1. With TunerCat all you do is go in and change stuff to the original programming and then save it as another file correct? Or do you have to make a program then download it on to the PCM? Guy

Nothin? Nobodys had to remove this stuff? Guy

Holy moly! I still just cant grasp the fact that 3.8 liters can produce that much power! I need a turbo! LOL Guy

#1. Flooring the gas or holding the throttle plate all the way open on a fuel injected engine will turn off the injectors. What is your TPS voltage when the throttle is fully closed, engine off. It should be at about .5 and no less than .23V or it will set a code. When I installed the my 58MM Holley TB I had to round out the holes on my TPS sensor to get it back down to .3V so that it would stop setting the Code 21(TPS too High). Heres what I suggest. Go to http://www.alldatadiy.com and buy a subscription for a 1995 Camaro with the 5.7. Its way better than a Haynes and it gives trouble shooting info and lots of pictures. Its $25/year for your first car and $15/year for any car after that or for resubscriptions. IMHO its money well spent. I would have spent way more time screwing around on forums asking questions and not getting the info that I need to get my LT1 running like it should if I hadnt have bought that subscription. Trust me on this one! I could give you the info for a 93' LT1 but the injection system isnt wired the same because the 93' is bank fired and not sequentail fired like yours is. Guy

Yeah Sunday would work better for me. Guy

I am supposed to work next saturday but if thats the date for the BBQ I think I can switch with another guy so I can have off that day. Let me know asap so I can switch! I would love to meet some other Hybrider'z! But there is no way I am bringing the ZX. Its 1/2 torn down to get ready for the painting process! Guy

IMHO, you need to spend some time in that engine bay and clean up all those wires and hoses! My engine bay used to look like that before I went back through it and cleaned it up. I am much happier now. Yeah its not fun but its a lot more fun popping the hood when the engine bay is nice an tidy. I am actually going to clean it up even more when I reinstall the engine after I get the car painted. Trust me on this one. Otherwise it look like its going to be a really really really fun car and quite the sleeper! Guy

Those will deffinetly look nice on your Z32! 8) Guy

WTH? There is no reason a kid should be protesting. Guy

How do you guys get off ureathan glass sealer off? I used some stuff made by MOPAR and it sure isnt fun getting off. I can get most of it off by cutting it with a razor blade but I still have some residue left over that I need to get off before I paint the car. Will carb clean work? (I dont have any out in the garage at the moment or I would have tried it) Thanks, Guy

I knew it could be done! Just no one has ever had the balls or $$$ to do it! This guy needs his own site so we can watch the progress! Any idea on a completion date? Guy
