Angry new problem

ok, i replaced the waterpump. put it all back together but i cant figure out where one of my electric plugs goes ...it is the one in the same "bundle" as the plug that goes into the MAF tube in front.

Anyway ..the car wouldnt start ...it tried and tried but wouldnt catch. I jumped the car and it started. turned it off ..tried to start it and it wouldnt start ..any ideas?

thx

Coil connector? I think there's 1 for 96-97, 2 for 93-95.
That and the MAF connector should be on the right side, left side is your opti, iat, and coolant temp connectors, and generally the car will start with those unplugged (although not very well in some cases). My opti connector was mangled up, but it still started, was just doing the virtual rev limiter thingy.
Someone tell me if I'm wrong, it's been awhile since I've unplugged everything...

You have a couple sensors around the general area...

Coolant Temp (PCM) - goes in front of your waterpump. The sensor screws in, so if you did not transfer that sensor from your old pump, to your new one, then you must do that.

Engine Temp (Gauges) - goes on the side of the head between spark puls 1 and 3 I believe. This is not necessary for the car to start.

Coil Module - plugs into your coil module bracket, there are two. 1 goes to the coil itself, another goes to the bracket. Cant recall exactly.

Air Pump - if you still got it connect it, it should be dangling around the immediate area.

MaF - goes to your MAF sensor

Make sure you coil ground strap is tight.
