E30 cranking but wont turn over after timing belt

[staysideways]

Hi guys i need your help. We did a timing belt,water pump,camshaft seal and oring,thermostat on my friends car and now it cranks but wont start. First i thought i did the timing wrong and bent valves. But no double checked timing and its right. All tdc marks line up.the belt is on firm and everything is connected. Except for radiator and hoses. I am getting yellowish spark and the injectors should be firing if all cylinder are flooding and weting the plugs.

Pulled plugs and dried them with compressed air. Double checked spark still have it. Put the plugs back in still doesnt turn over. Pulled them out they are wet again.

I have a crank position sensor on the way now. But it will be delivered to me in 8 hours. So any help would be greatly apriciated.
Btw the rotor and cap are fairly new the rotor has lots of life left on it and the cap has minor carbon but i sanded those with 2000 grit sand paper twich over each of the prong things.

Could have we disconnected something or banged the crank position sensor?

Pull distributor cap and check rotor, since you just had it apart. Spark should be bright blue not yellow. Possible coil?

You can test the crank sensor. IIRC it should have about 600 ohms on pins 1&2, and very high ohms between the 2&3 and 1&3 pairs.

You put the plug wires back in the right order on the dist cap and reconnected the cam sensor, right? Test the main coil lead for resistance too, should be 3KOhm IIRC.

Go backwards through your work and verify every change you made along the way.

Double check and make sure the CPS and CID are not mixed up. They can plug into each other and are right next to each other, so they can get easily get crossed/mixed up. I have done this once and was shiting bricks until I double checked the timing and knew something else was going on. I swapped these plugs and it fired right up. good luck.

I figured out the problem the rotor was defective it would only fire a few times until it would give up and cool down
