Hey guys and gals.. both of my cars are down right now. I just fixed the broke. Intake nipple issue in my 335 got everything back together and it doesn't crank. I'm so tired I can't think straight. What am I missing that the car won't crank? Both connectors on top of the manifold are connected, the icv plug in is connected, the vacuum lines are plugged in....

Did you leave a light on somewhere or the door open? Maybe your battery is dead??

Ok I found a plug under the intake but without having to uninstall everything, I don't know what it plugs into. Green inside the plug and has three pins... Ideas?

Lights all turn on..

Did you have the intake manifold all the way off the car?

It connects to the charge pipe

charge pipe connector is for the MAP sensor and it has an orange/red rubber grommet, not green. Unless I'm remembering incorrectly.

It's probably the single wire line that goes to the starter solenoid. Engine DEFINITELY won't start if it isn't plugged in. It goes from the engine electronics junction-box-thing (under the throttle body area) to the starter. It's a single white wire (usually) with a metal wire style lock on the connector, correct?

your correct its a single wire but im sure it doesn't have three pins . still sounds like tmap but that wont have anything to do with cranking .
I would at least check connection like bmw md said you can just stick your arm in there and feel if its connected if so I have no idea without a pic of connector

[robc1976]

There is a fuel pressure regulator sensor down there also...could be it...I will check in a few for you

[vertigo44]

take a pic and post it. Its prob one of the connectors that others have already mentioned. I have taken these off numerous times to do intake valve blasting. The starter is just under the intake. Also check the black box like connector under the throttle body.

check some codes.
most of the time if somethings unplugged it will still read the fault even if the engine is off.

I found the plug, cant access what it is supposed to connect to so when I have time it will all have to come back out. Its one of the black connectors on that devil spawn box under the manifold. Those screws are horrible btw

2 tiny flat head screw drivers at the same time will disconnect the so called black box its easy don't get why everyone is having trouble with it .

It has to be the wire to the starter that I mentioned. Nothing else under there would prevent the engine from cranking. The wire I speak of connects to the starter itself on one end, and to the front of the black box right near where the fuel pressure sensor harness plugs in.

thats got to be it then... i cant reach it without pulling everything back out of there... guess it have another few hour project under my belt hahaha
