'95 tsi awd 6 bolt swap. Need Help with a no start.

scizzle · 12-01-2006, 03:00 PM

I have a /95 tsi awd that i put a brand new longblock into. I did the 6 bolt swap and after a long road got it started... but after 4 miles the flywheel fell offdue to incorrect bolts, they were slightly too short. it sat for while till i got around to replaceing the TO bearing and cluthch disc. PRessure plate and flywheel looked fine. got it all back together, again, and this time i have the no start. I have 155 compression all the way accross, i have new plugs, correctly gapped with new wires. i am getting spark for all four cylinders. looks maybe just a little weak, but overall ok. i have 45 to 48 psi in the line from the filter to the rail, which is slightly high because of the 255 lph fuel pump. new FPR. New starter. new alternator. all electronics work. new battery and cable connections.fresh oil and coolant. correct base timing. the engine rotates fine but will only fire intermittently with a backfire every now and then. im stuck... Suggestions?

Did you check to ensure you coil is not bad?

I got the manual and there were three checks to do with a meter to see if it was good and it checked good in all three.. Dont remember exactly what they were. resistance nembers.

The only other thing I could think of would be a short in your wiring harness somewhere maybe...

I'm not sure but doesn't the starter spin the flywheel to start the car? If so
I bet you its the starter missing the flywheel. Just check to make sure those are alligned properly.

yeah, the starter does engage the flywheel. it is called a pinion gear it swings out to engage the flywheel. it is engageing the flywheel or else the engine would not rotate, only the starter would. thank both of you for your input. if anybody happens to ask around or hear or find out anything else post back or pm me. thanks. until then...

has anybody heard of having too much fuel pressure not letting your fuel injectors open? called clicking? And what should the fuel pressure be at without the engine running?

Fuel pressure should be set around 40psi. That is what the stock setting is. But as for to much fuel pressure. What are we talking about here? Even if you put a Walboro 255lph HP on there, running the stock FR you should still be able to run the car. The bigger fuel pump will over flow the stock FR but it would only degrade performance enough to make it idle rough.

That is the fuel pump i have, with a stock regulator. I figured i should still be starting up. Are there any little stupid things that if you leave them unplugged it won't let the car start, such as a reverse light or anything?

Just go through and double check the wiring harness, that was always the cause of my car not starting after getting the head back on.

Have you tested the injectors to make sure they are opening up? That would be my guess, make sure they are all plugged in.

scizzle · 12-12-2006, 02:02 PM

Ive went over the harness many a time, granted i could still be missing something. i do have one plug not plugged in, but i think it is for somehting on a 7 bolt since i did the swap. i have tried to find out what it is form schematics but i cant find it. so a question for all of you with 2nd gen dsms, what does the 3 prong plug located just after injector 4 and 3 in the harness. i will get wire colors for it today if that would help..

If you can post up a picture.

scizzle · 12-12-2006, 06:20 PM

i could try to get a picture either later tonight or tomarrow, but the wire colors are light green with a white stripe; dark green with a yellow stripe; and a black one. The car was running at one time, and when it was i dont think it was plugged in, but i cant be sure and the car won't start now so.. thanks for all the input thus far as well everbody.

The last thing ive came down to is the ecu. If the ecu is bad, how can i check it, or can i have it checked?
