I know you people need to get your post count up.
So I have a new harness on the way to me. Hopefully thats the issue. Also got some pics to up load.
I have a aba that I have not been able to get to run. It is obd2, supposedly from a Passat or at least it has the Passat intake mani.
It is a swap into a ce2 91 Jetta Coupe. Supposed to be easy, right?
It just cranks and cranks. Almost starts but no. It has a cam, we think it's a 268.
So with help from others we have verified fuel presure is good. Put in new gas. Checked that the timing is correct. Made sure the injectors are spraying. Put in new plugs. Verified that we are getting spark for sure. Sounds like it wants to run and has compression.
Also sent in a camera to look at the valves. They appear to be seating correctly and no problems in the head.
So it has been suggested that I need a new harness. One from the Passat obd2 aba. I just can't understand it. What would the difference be in harness from the Passat aba as opposed to a mk3 aba?
Only things that have not been done is to actually check compression in each cylinder and connect the scan port and see what codes it throws.. which I have not done yet.
Any suggestions or help would be greatly appreciated.
But since then I tore the harness out and swapped it. It must have had a few wires jumped for ce2 swap already.. now that I have a perfect stock one in I am trying to figure out what wires need to go where at the fuse box.
I put a fuse in this black plug and now it just cranks. So I am getting back to where I was..
I know its just the simple slice or something.. It's OBD2
Are you sure the distributor timing is 100% correct? I had a friend do this swap in a mk1 and it was giving him the same type of non-starting issues. We checked the distributor timing, and sure enough it was out. Reset it correctly and she fired right up.
Today I was messing around noticed this. The cam and flywheel marks just were just barely off again.
So I slipped the belt off, turned the crank clockwise and lined it all up again. Put the belt back on and hand cranked it few rotations to make sure the marks lined up and they did.. tried to start it. Same. So I checked my marks and sure enough, they are off again. I think it's slipping on the crank somehow.
Well, all of the keys were good.
So we put it all back together with a new belt and proper tension. Still the same. The timing marks stay on now, so we know its timed correctly but just cranks and cracks. Gonna try a new distributor, cap and rotor and if still no worky then I guess pull the head.
