88 2.8 GT about to be fixed! BUMPED!

[Vampcrist]

SO last things left IAC MAP MAF(should be disabled) ECM and/or all 6 injectors

Fuel pump and pressure regulator haven't been changed eather but I don't think they need it...

I'm at total loss now maybe later on today I can get it back in the garage and get a video up after it desides not to run/start see if that wont give you guys some idea of whats going on.

[Vampcrist]

Alright so tomorrow I'm putting the plenum back on get everything sealed back up and change the MAP out and see where we are at after that. Also might do some cosmedic touch up's that I'll post pictures of after it's all put back together.

[Money pit Beretta]

Pics and video? I'm still watching man. Are you sure the chip is good?
With all that you have done when you get going again it should run damn good.

[Vampcrist]

Well I didn't get it home before dusk after a run today I'll get a video going tomorrow afternoon on it after it does it again. The chip I'm starting to wonder about I think I'm going to see if I can't find a nother ECM for a good price to give it a check with. Let you guys know more tomorrow.

[Vampcrist]

Okay so this video is about 5 to 10 minutes after it got to normal operating temp started twice after about a minutes rest in between then this...

(this is the longest load on a 1 minute video I've ever done!)

Let me know if that makes since for you. I just dont get why it would start to idle out and just poof nothing.

My autocross videos take around half an hour to upload for around 125 - 150mb.

Your sure it's getting fuel? And wow your starter is loud, is it new or something?

[Vampcrist]

Yeah I put in in about.... 3 months ago and its been down since a couple days before i made this post. I bought it new too wasn't a reman and even when it wouldn't start it's always had pressure at the rail haven't had any readings under about 37psi when warm and running. It's strange how it just goes for a second and then just poof nothing if anything I'm going to have the fuel pump changed out probably in 2 weeks though unless I can find the right VIN to be able to pull out the pump and if I'm lucky the ECM.

[Vampcrist]

I'm about to the point to just take it in and get it scoped. Tired of trouble shooting and atleast that way I don't have to worry much more about what's wrong I'll know right off the bat. I'm about to the point that I'm done working on it myself get it scoped and then fix whatever is wrong. I just can't wait to hear "Ohh change this that should work" so I can be umm yeah did that and that and those as well. Now it's just finding a worthy shop to take my car to. I'm always afrade to take cars in I don't trust to many mechanics not even myself!

[Money pit Beretta]

I could be wrong and most of the time I am, but I would try a chip. Try one from WOT-Tech. Yeah it's best to have the car checked out. You have put enough money in and it's still doing it.

I'm about to the point to just take it in and get it scoped. Tired of trouble shooting and at least that way I don't have to worry much more about what's wrong I'll know right off the bat. I'm about to the point that I'm done working on it myself get it scoped and then fix whatever is wrong. I just can't wait to hear "Oh change this that should work" so I can be um yeah did that and that and those as well. Now it's just finding a worthy shop to take my car to.

Then you need to make a list of what you have checked, and what you haven't. It's something that your missing, and it's just a matter of figuring it out. List it here, and maybe start grabbing parts off salvaged cars at an auto recycler. It's cheaper and they usually are GM parts. At least this way you KNOW what the problem is and if that part goes out buy a new one.

[Vampcrist]

Yeah I have before for things on it. The block is out of a corcica I got from a salvage yard. But as for the things I've replaced..

IAC
TPS
Ignition Module
All 3 Coils
CPS
O2
Oil pressure sending unit
Fuel pump relay switch
Checked fuel pressure
Checked OHM readings and Voltage readings on all 6 injectors did NOT pull them to check the spray
Fuel Filter
Like I said before it's got a remanufactured ECM from GM
Unless I'm missing something MAF MAP fuel pump and ECM is all I think I have left and all are rather pricey even with my discount

[Cliff8928]

The sticker on the ECM may just be to state that the speed density mem-cal has been installed, not that it has been replaced. That is unless it has actually says remanufactured on it..

[Vampcrist]

It does actually say remanufactured

[3X00-Modified]

have you tried unplugging the MAF sensor and seeing if it will run? A bad maf will prevent it from running, but if unplugged sometimes it will run and idle "ok" enough to know it runs.

Also what chip is installed in the ECM? Grab the ID off of it to be sure you have a proper ROM in there. The ECM may need a reflash with the proper ROM to run the car even though its a reman.

[Vampcrist]

Yeah it didn't stall out when the MAF is unplugged at all. I'll grab numbers off the ECM tomorrow and let you know.
