Ok, after researching idle problems, found one thread where the guy was having the same issue as me. Starts, but won't idle past a few seconds. So he unplugs his maf connector and pooof-starts and purrs like a kitten. Bad MAF, right? 94 LT1 stock except for headers. Bought a reman. maf, same issue. I start the engine, its idling and I plug in the maf connector and within seconds, dies. What could be causing this problem? Engine ran at a bit of an high idle for approximately three minutes, then stalled. And now, SES light not coming on and I can't hear the fuel pump turn on either. Any help or suggestions would be dearly appreciated.

 

Check fuse #5 in the end of dash panel - supplies 12V to the MAF sensor, fuel pump, PCM (switched power), and theft deterrent relay. If it's blown, you're going to have to figure out what caused it to blow. The MAF circuit would be the first one to check.

 

I neglected to mention that I am restomodding this into a 68 Impala SS. I have checked all of the fuses provided with the new, custom harness and they are all intact.

 

Harness off the MAF sensor, do you have 12 volts between the pink wire (12 V) and black/white wire (ground) in the harness connector? Pretty sure it's a black/white wire. On my phone and in location remote from my reference material.

 

That's correct according to the manual. The third wire is the yellow signal wire.

 

Thanks. I bet I've typed that sentence at least 100 times over the 17 years I've been on this site. But I'm enjoying myself at a convention in Atlantic City (NJ), and my mind is not all that clear.....

 

Have a good time. Might get a little windy there by Monday.

 

I will check it out and get back with the info.
