Fml-- Misfire (And I Searched)

[quickness]

Okay so I post mainly on the UK GTR forum... But been told that you guys might be more helpful. So here it is in a nut shell.. long nut shell ..Okay I searched and searched but didnt find a problem anything like mine. I know about the coil packs, the ignition chip, the plugs and the CAS. This one has me boggled.. Oh and the harness. To start I have a 1993 GTR fully built.

So I had the car entirely re-wired. Why not its a 93 and 93 wires were never ment to last 20+ years. So no problem with the loom, unless its loose but i checked.

So thursday night the car sat still for 30 minutes while we tuned the car for cold start. NOT A SINGLE PROBLEM.

So friday I take the car to get something done. Car starts up PERFECT no problem, sounds awesome. I wait a few minutes to let it warm up and then right before I get in the car it dies. I try to start it no luck, the mechanic tells me to check the main connector near the firewall, he was right a little lose, but I fixed it and good to go.

I drive about 10 miles if that and then the car starts to misfire, 2 blocks later its worse, sounds like a boat, as my friend says.. So I stop the car and have it towed to the house. Now the car wont start at all.. Just cranks but no turn over.

Get it home, I take out all the coil packs, the chip and put everything back to make sure it was not a loose connection. Car starts up NO PROBLEM. I even drive it a couple of blocks to make sure... GOOD TO GO..

Then the next day I go to start it up.. Bam no luck... wont start... So I remove everything again and then bam it starts up but is misfiring. So i start to unplug each coil-pack for a second to see which cylinder is going. Yet each time i disconnect the coil pack the misfire gets worse, so no luck on determining the cylinder.

So now I am sitting here trying to figure out what the hell is wrong. The mechanic is worthless as he doesnt care, and honestly I dont care about him.

Oh not sure what the hell this means, but I charged the battery fully yesterday. When the car runs the alternator is charging the batter. I turned the car off, lights, lamps, everything. Yet two hours later the batter was dead.

Update to these issues.. The battery was replaced as it was totally dead.. So now there is a new battery in the car.. I also did a test on the coil packs. Was told to use a multi meter set it to 200omhs and then test the postive and negative terminals on the coil pack.. All 6 read a 1.0-1.1 with a .8% error. So I dont know if i tested something wrong or if thats okay as I am running SplitFire coil packs.. Also I checked the plugs, the fuel and so fourth.. ALL good to go..

I NEED the car to be running by Friday... PLEASE HELP... thanks

Ok so with the new battery its still no good? I would start by checking all the new wiring loom. Check all the connections and make sure none of the pins have backed out of the plugs.

Check all fuses too.

Is the fuel pump priming? Take the fuel line off after the fuel filter and check fuel is coming out when cranking.

What ecu?

it sounds to me like a bad connection somewhere. you said that if you disconnet everything and reconnect it that the engine runs. so i would recommend dicsonnecting and reconnecting one thing at a time until you can start your car then focus aroumd that
