2001 Jetta 2.0 turns over no star/no spark
My buddy and I have replaced the crankshaft sensor,
camshaft sensor, speed sensor, ignition switch, ignition
coil, fuel pump relays, and lastly, I replaced the MAF
sensor by pulling a 99 MAF sensor from a junker. The day
before I replaced the MAF sensor, the car started every
time and as it should. The exact moment I tried to start
this Jetta, after replacing the MAF sensor, it will not start
INTERMITTENTLY. Sometimes it gets spark after trying
for minutes and backfires LOUDLY and sometimes it
doesn't, and sometimes it starts right up.
WHAT IS HAPPENING. Please, I am at my wits end and
this is my wife's only car for work and to drive my
daughter and her around. Please, someone help
diagnose this.
also, after replacing camshaft position sensor, all codes
are gone.
