I ran these test and there were some pins not on the connector so I could not do the test (38&55). I had a problem w/ my some grounds, knock sensors and my injectors. So w/ 55 missing I could not do the ecm power supply relay, fuel pump relay, 1 of the grounds and none of the ignition coil wiring. Now onto my #'s.
Main Grounds: (all should be approx. battery voltage) 96 VR Jetta 5spd
pin 10 & 54, .026v
pin 33 & 54, .28v
pin 55 & 54 I couldnt check b/c there was no 55
Fuel injector coil resistance: (all should be between 14-21.5 ohms.)
FI1 pin 23 & 24, 223.2 ohms
FI2 pin 3 & 23, 223 ohms
FI3 pin 23 & 26, 223 ohms
FI4 pin 4 & 23, 221 ohms
FI5 pin 23 & 25, 222 ohms
FI6 pin 2 & 23, 221 ohms
Throttle pos. sensor:
pin 33 & 41, OL
pin 33 & 40, OL
pin 40 & 41, 814 ohms
Knock sensor 1: (max 1.5 ohms)
pin 33 and 34, 4.87 mOhms
pin 34 & 56, OL
Engine speed sensor: (500-700 ohms)
pin 67 & 68, 852 ohms
Heres a few of the major issues I have w/ wiring. I need help b/c this ground issue is where I think my problem lays and theres all common grounding points all pointing to the "ground connection (control module) and (end stage) in Motronic Multiport Fuel Injection (MFI) wiring harness". Thanx for your help in advance.
