Hi Guys, hope someone can help me with my Vr4 and it's starting issues....

So I'll give you the run down on what has happened, I'm running a Haltech E8 with a COP setup.

At the start of the year I took my galant into Garage 101 to have it tuned and one step closer to getting it rego'ed.

They had it for a few days trying to sort things out with it and get it running right, they called me and said that it was all sorted and ready to collect. I went in the next morning paided the bill and drove it home. On the way home it started to miss fire and a few back fires which I put down to it being cold and I got it home without any real issue.

It sat in the garage for about a month till I was able to work on it again. I booked it in for it's rego and the day before I took it for a drive to get it warmed up and see if there was any leaks that I needed to fix. I drove it down to the shop, which is only a couple of Kays away and on the way home I opened it up to blow the cobwebs out. Just as I was pulling into my street it started to miss and play up and as I pulled into my drive way there was smoke coming out from under the bonnet. I popped the bonnet and number 2 coil was burning/melting, I disconnect the battery and changed the coil, checked the wiring and put it down to being a bad coil.

I took it for another test drive and it did it to me another two time so then I knew there was something definitely wrong, I rang Garage 101 and told him what had happen and he said that it must be my wiring....I compared his tune with the old tune and the only thing that was different was the charge time, old tune was 2ms and his was 2.5ms he told me to change it and try again.

So I was all out of coils and had to order some in before I could test again, so today I change the coils and checked the wiring again and everything seems all good but now it won't start grrrrrr the only way it will start is with the throttle wide open and it only just runs.

I have even tried to put the standard coils and plugs on but still the same. I've checked power to the coils, checked the earth, checked continuity with the signal wires to the ecu, checked MPI module and relay and they all test out ok.

Is there something I'm missing....? Any advise would be great

Thanks

Seems odd to only run at wot. Tps throwing something out....

[RocksolidGVR4]

Yer it's strange, I've calibrated the TPS and checked it on the laptop and it seems to be working correctly.

Changed the CAS?

Is there a chance that after blowing three coils, you may have overheated some wires in the loom? Perhaps there are some damaged/shorted wires in the loom.

Take it back

If you called me up to come look at it I would...
Start from the start.
compression test, check your cam timing.
Put a timing light on each lead to verify spark and timing of spark.
Fuel pressure, put your multi meter on duty and measure each of the injector duties at cranking, to ensure you are getting injector signal.


Work from there.

So today I final got the beast started, I remember something that the tuner told me that when he was tuning it for some reason it wouldn't save changes in the ecu... So I reloaded the map and put some new spark plugs in and hey presto it started.

Take it back

This......^

I would have taken it back but because i work away and live in Melbourne now it makes it harder to take it back because im only in perth a few days every month.

I took it for a drive today and everything seemed to be working ok which is a good thing. Im flying out in the morning and won't be back in perth for a couple of weeks so it will have to wait till then till i can take it for a proper drive.
