I checked plugs, wires, cap, rotor, wiring, grounds, icm, timing, coil power (coil is brand new msd), alternator is around a month old, fuses are good, replaced crank position sensor, battery is good and it still won't start. I have fuel and the fuel pump is turning on. I'm not getting spark. Any ideas? Thanks in advance.
Edit: Just replaced starter (was bad) still no start. Someone said maybe pick up on distributor?

Im on the same boat.... Replace the ignition coil and just got the crank sensor and will be replacing that tomorrow, would you happend to know the location of that sensor it would help out....
I do, its a pain in the ass, its basically behing the oil filter and front motor mount, have to remove the mount to get to the allen key bolt, really easy with the mount out the way. I actually removed the relay for the ecu (digifant for original car, its a swap for me) and it almost started so I'm going to get a used ecu tom. and try that. I'll post on here if it works.
Ecu didn't work. Got brand new dist. and nothing. Set to tdc and nothing. Now I am getting 12v into dist. but nothing through plug wires. Any ideas? Bad plugs? Thanks.
have you done the tests to determine if you are getting spark yet, you can use the specialty tool or do it the old way with a screwdriver in the plug wire. if you are getting no spark at all you probably have an odd variable not allowing spark to happen, such as: clutch position sensor, transmission selection reading incorrectly, crank sensor not reading, or cam sensor not reading, or cam and crank sensor telling the computer that you are not correctly timed.
I have tried the old methods and what others have suggested. I bought a specialty tool just to see and will check tonight. I just replaced the crank sensor and the cam sensor is new with the dist. I have set it to tdc when I put in the dist. and the new cam gear. Did the motor have to be tdc when I replaced crank sensor? And it is a 5spd manual so I don't know if I have either of the sensors you first listed.
i am not positive VW's have the clutch pedal position sensor, its like a dummy switch so you cant start a manual without having the clutch engaged, my 96 gti doesnt have one so not sure if you would have one. you didnt need to have the motor at tdc when installing the crank sensor, but perhaps the cam gear is the problem, are you 100% positive that your timing is set correctly, i have personally made this mistake once. i never asked if the car ran before the motor swap( as indicated by your name)
Yeah I don't have that sensor. I am a 100% sure it was set at tdc, the flywheel mark was showing and the #1 piston was at the top. Yes the car has run before, the swap was done in 00-02 if I remember correctly (previous owner did the swap).
Does the motor just turn over? In my last MK3 jetta I had an issue with it not starting and after many head aches and replacing of various things I ran my code reader on it and it came up with some number that I can't remember. Turned out to be the impulse sender. Not sure if that could be your same issue.
Yes it just turns over until I let go of the key. Well the previous owner deleted the obd port so I can't run the reader unfortunately. Where is the impulse sender if you don't mind telling me?
I am not 100 percent sure were it is because I just got to frustrated and brought it in. I believe tho it is located somewhere a little above the oil filter and the other part connects in around your coil pack. It should look something like this 00 2000 Volkswagen Jetta Impulse Sender - Engine Electrical - Bosch - PartsGeek .. or if you have a Bentley book that will be able to help as well.
Yeah me either. I have posted on this and another forum and haven't gotten much help/insight to what it might be besides what I have tried. I pulled the dash to go through the wiring just to make sure no wiring is causing a problem and to clean up the previous owners mess of the fuse box area.
Does your Check engine light turn on with key on engine off? (KOEO)
If it does, does it go out AS SOON as you start cranking? This is important. OBDI this won't matter. This is a really easy trick that I use on older OBDII to diagnose crank no starts. Also, you might want to get a DLC wired into there. You won't go very far just replacing parts, and a scanner will take you very far if you know how to read the data right
