1g 2g swap complete...Wont start
 

I am finished with the swap but the car wont start. I have done all that i can think of.. any help here? Order of plug wires and where they go on the 1g motor and coils.

Re: 1g 2g swap complete...Wont start
 

Does it even try and crank over? I had the same problem and I somehow messed up on the CAS. I wired 2 wires wrong.

Re: 1g 2g swap complete...Wont start
 

Ya it cranks over. I put the one wire in the rectangle plug and the other three into the triangle plug. Any ideas or hints? Please let me know I need this done. You know how that goes.

Re: 1g 2g swap complete...Wont start
 

I used the 1g coils. Should I use the 2g ones and please help me out on the wiring with them.

Re: 1g 2g swap complete...Wont start
 

What does everyone suggest for the coils. 1g or 2g for the swap?

Re: 1g 2g swap complete...Wont start
 

Isn't there something that needs to be inverted depending on the year of your car (i.e. especially 95-96). Double & triple check your wiring, that is probably the problem.

Re: 1g 2g swap complete...Wont start
 

I did do the wiring with the CAS by wiring in the one wire to the rectangle plug and the other three wires to the triangle plug. It seems like it fires one or 2 cylinders every once and a while but wont start all the way. sorry for the lack of knowledge here and thanks for the help.

Re: 1g 2g swap complete...Wont start
 

Have you checked the timing? When i did mine i found the Distributor in 180 degrees off. Its a Easy mistake to miss

Re: 1g 2g swap complete...Wont start
 

Do you think that would hapen if I just took off a working head off of a 91 tsi turbo and bolted it right on without any cas removal?

Re: 1g 2g swap complete...Wont start
 

i work for a dealership its just something the guys here had me check on my car and it worked so i would ck the timing. Those engines are pretty easy to time as well. Otherwise ck for fuel pressure..

Re: 1g 2g swap complete...Wont start
 

These cars don't have a distributor, although the CAS can be 180 degrees off.

It sounds like the plug wires are in the wrong order. Looking at the 1G coils, it should go from left to right 4-1-2-3. Cylinder four is the tranny side of the engine.

Re: 1g 2g swap complete...Wont start
 

I went through all of this and still nothing. the most ill get is some poofing sound like its coming back through the intake. And sometimes it will try to start but just barely at all. These things frusterate me. Any help is appreciated.

Re: 1g 2g swap complete...Wont start
 

Ok so I tryed all of the wiring and fell back to where I was. This must mean that I had it right the first time. It turns over and sputters but just wont go. It no longer puffs or backfires out of the intake so I am sure everything is right. The timing has to be on because the head wasnt messed with off of the new 6 bolt. Also I was thinking can a CAS start to go bad but sputter some times? There is spark as well so I have no clue what is going on here. Any advise is appreciated.

Re: 1g 2g swap complete...Wont start
 

When you purchased the 6 bolt longblock, did you physically see it run to where your above statement can be assumed true?

Re: 1g 2g swap complete...Wont start
 

If you can't get this going by saturday, I'll swing over since I'll be in the area.

Re: 1g 2g swap complete...Wont start
 

Ok so I have wired everything right. I have spark, fuel, and car wants to try and fire a bit but no start. Could the CAS be shot where is gives a spark but doesnt run? Help here please.

Re: 1g 2g swap complete...Wont start
 

Yes, I'd try another CAS. Mine went out once when I got some water on it.

Re: 1g 2g swap complete...Wont start
 

Did it make it kind of want to start but just didnt. And did it also have spark?

Re: 1g 2g swap complete...Wont start
 

Well is there anyone that has a CAS that I can use for a few minutes to test it out?

Re: 1g 2g swap complete...Wont start
 

Ok so I rechecked the timing and that is right on. The CAS is right on as well. I was trying to start it for a bit and noticed that the manifold was warm after a few minutes. Remember the car doesnt start but just parely trys to fire. Any ideas for this?

Re: 1g 2g swap complete...Wont start
 

I've been following this thread and these are my thoughts:

Did you seal off anything in the intake/charge tract with a rag?
Do you have fuel pressure?
Are your injectors not plugged in the right order (harnesses)?
Are the plugs in the right order?
Are you throwing any CELs and if so what are they?

Re: 1g 2g swap complete...Wont start
 

Don't forget to cup the balls

Re: 1g 2g swap complete...Wont start
 

Ok now I went out and checked each indavidual spark and the 2 sets of plugs do as follows

SPARK - - - spark - - - spark - - - spark and so on like i think it should and the other two do this

Spark - spark - spark - spark - spark so eother one isnt getting enough spark or the other is sparking too much burning the fuel off when the valves are open. If this makes since or you have seen this before let me know. Also do you think that this could be the CAS being bad? I dont see where else it would cross.

Re: 1g 2g swap complete...Wont start
 

have you checked spark with a screw driver? its a easy trick thats real old school, we use it a lot on the circle track cars, I mean yah you keep saying you have spark but that test is a for sure tell if you have it... and also check your throttle position sensor and your coolant temp sensor if either read incorrect it alters yours fuel and can cause that problem

Re: 1g 2g swap complete...Wont start
 

Which one is the coolant temp sensor on the 1g? iis it the one white plug on the upper of the thermosata area or the black one on the lower part?

I also tryed a new CAS and that didnt help so...

Re: 1g 2g swap complete...Wont start
 

Still nothing. Any ideas?

Re: 1g 2g swap complete...Wont start
 

I am down to thinking that it has to do with something that makes it spark abnormal as listed above. Any ideas let me know. Could the ecu do this? It ran 100% before swaping the tranny and motor.

Re: 1g 2g swap complete...Wont start
 

Any more ideas here?

Re: 1g 2g swap complete...Wont start
 

If you're positive that it's the ignition, start with the plugs and work your way back. Plugs, wires, coil, wiring harness, ECU. Check your ground. Make sure you're timing is correct.

Re: 1g 2g swap complete...Wont start
 

Look over the wiring diagrams on how to wire your CAS. If you're having a problem with it, then I'm certain that it's the wire job. If it's not, continue to scratch your head thinking of what would be related to your problem.

Re: 1g 2g swap complete...Wont start
 

When Kyle at MAPreformance did my 6-bolt swap in my 95 it also wouldn't start. It would barely turnover then just immeadiatley shut off. He messed around with a few things and found out that it was the firing order. Try messing with it some more.

Re: 1g 2g swap complete...Wont start
 

The spark seems to be wierd as stated above. I know that it is wired correctly unless the 95s are way different. Let me know. It has fuel and spark and I am down to the very end with ideas? If you have done the swap on a 95 and have had similar problems let me know.

Re: 1g 2g swap complete...Wont start
 

Since I have spark does anyone think that it could just come down to the ecu being bad for some reason?? The coil works and I tryed a different one and same affect. The spark is different off of one coil then the other like almost a bit too much spark. I tryed new plug wires and the same thing. Its all wired up right. I put in new plugs gaped and tryed old ones. I have fuel pressure and all injectors read same voltage meaning they are opening. I even sprayed some starter in the intake nnd no difference so its getting fuel. Thought it might be flooded so i repeaditly took plugs out and cranked until dry plugs. No better and not flooded even with new plugs again. Tryed a new CAS and no difference. Messed with all different plug order and got it on the right one. It comes down to a wierd spark and maybe bad ecu to me. Anyone have an ecu I can try? Let me know what you people think. Thanks for the help.

Re: 1g 2g swap complete...Wont start
 

OK...
We found out that its not the ECU, Fuel(anything), Transtistor, Coil or CAS.
I brought over my ECU and my Nearly brand new transistor and nothing happend differently.

When we play with the wire on the CAS(either the + or -) the fuel pump runs(when key in on position) and the fan starts then shuts off. This is where I was confused. Why does the fan come on when we plug the CAS in? It goes for like a second then shuts off, almost like the relay clicked on and then shut off right away.
As for the spark, It looks a little weak and doesnt seem to fire very steady.
Someone help us out!!! Im getting pissed off and its not even my car.

Re: 1g 2g swap complete...Wont start
 

Yes I agree if there is any help or ideas post and we can get another dsm back on the road.

Re: 1g 2g swap complete...Wont start
 

Have you checked the plug gap? Are you sure the CAS isn't off 180*?

Re: 1g 2g swap complete...Wont start
 

Plug gap was fine and the CAS is not 180 out(He tried that and that made it worse)

Re: 1g 2g swap complete...Wont start
 

I thought I read before that if you invert the CAS you need to switch the 1 and 2 also the 3 and 4 plug wires. I know you said you tried all combos.

Was the fuel system and pump primed when testing the combos?

I may be way off or going over covered ground. Good luck.

Re: 1g 2g swap complete...Wont start
 

It is nothing fuel related, We got fuel into the cylinders and the fuel pressure was fine. We tried all combos of 4 and 1 wires switched with 2 and 3 wires.

Re: 1g 2g swap complete...Wont start
 

I would look at the plug wires and the wiring swap. After that try swapping coils.
