Cleaned MAF Sensor, now won't start...
 

Cleaned the MAF on My wife's 1999 Expy 4.6 and now it won't start. Just dies and won't catch....

Any help is appreciated...

Did you plug it back in? Did you touch it and break the wire?

Never knew that the 4.6 in the Expy was a V-6.......... :D

(Or do you have a 5.4 that's running on 6)

pull the neg terminal and let sit for a few mins?

glc, I dont think unplugging it wouldnt allow it to start- ive started mine before without it plugged in, although it idles like a '69 Chevy lol

Yea, it SHOULD start. We aren't getting the whole story here lol.

This isn't the V4.6 Forum.

i thought you were suppose to reset the pcm after cleaning idunno

I realized after I posted that I have a 4.6 v8. Sorry was a little stressed yesterday...
Everything seems to be connected...
The one thing I did do was spray it without disconnecting it. I didn't look up how to clean it 1st...


one of the mods can move this to V8 if they wish..

ok ... It runs, but does not idle. I found a broken resistor on the MAF (the back one)... .... off to the store.. I have the battery disconnected to reset things.

gotta get this going.. kids start school tomorrow.. lol .. deep breaths...

1 $130 MAF later and it is running fine.... Expensive cleaning...:mad:

Thanks..

The proper procedure for cleaning the MAF sensor is not to break anything.
