Question
I have replaced the lower intake manifold gasket. Trying to find 0 degrees on the crank. there are 2 marks on the crank i am assuming one is BTDC and one is ATDC. Were is 0. And does the computer have to go through any kind of relearn procedure? Timing is not adjustable, but I need to get every thing in sync. I have TDC one number one. HELP ME...Thanks

Hi; well if you took out the distributor, you will have to set up the motor. but if you never turned the engine over it should be fine, if you took off the drive belt it must go on in the same way you took it off , if the engine was turned at all, than yes you will have to re-set (pulleys) it and all pullies.0 is on tdc. I think the computer will not have to be touched but . if you go to the library the tech books there will show you step by step ok

| Comment | Actually come to find out, the injector on number one was not working. The pin under the injector electrical housing had gotten bent. But thank you anyway, just thought I would let you know what it was that was making number still misfire. | ||
