Car cranks but will not fire up
Listening to the video, apart from the battery sounding rather tired,
I did not hear any kind of pop or bang or sound that might indicate that the plugs are actually firing ? Have you checked for spark with a plug out of engine and grounded against a metal part of the engine? Easier to see in the dark rather than bright sunlight. Cheers... jondee86 |

I must point out that these are not stock camshafts
They are these http://www.catcams.co.uk/acatalog/7105137.pdf Plus my cam gears are adjustables made by Blox but have the same degree of adjustablility just as the tomei cam gears. Do you set up aftermarket cams like stock ones? |

You must have adjustable cam timing gears....
And then you must work with the timing in order to detect the new TDC of the camshafts you have now.... That catcams document has some angles, and you need to work with them.... I don't know. Can't help.... But search the web! You have lot's of info! Or wait for someone here.... jondee has the knowledge.... |

Alex170984 Wrote:And how would I be doing that?Most manufacturers will place the knock pins in their cams such that if you put them in with the factory non-adjustable cam wheels, the timing will be pretty close to their recommendations. In this case, 110/110. Likewise, the Blox cam wheels should have a zero marking, and when set at the zero marking, the Blox wheel should match the stock wheel. Therefore, if you set the Blox wheels to zero and put the knock pins in the same place as usual, the cam timing will be close enough to allow the engine to start. Put the engine at TDC on #1 cylinder compression stroke, crank pulley at zero timing mark, intake knock pin at 12 o'clock and exhaust knock pin at 5 o'clock. If the Blox pulleys do not have a dimple on the rim like the stock pulleys, place a stock pulley exactly on top of the Blox pulley and line up the holes/slots for the knock pins. Mark the correct tooth on the Blox pulley. Now you can use the mark on the backplate for positioning the pulleys There are other ways of setting the cams up, involving a DTI and degree wheel and a lot of arithmetic. You don't need that at this stage. Good luck. Cheers... jondee86 PS: One quick check to make sure you have the cam settings in the right ballpark, is to look at the position of the lobes. Set #1 cylinder to TDC on the compression stroke, and observe the cam lobes for that cylinder. The intake lobes should be pointing to the left, and the exhaust lobes should be pointing to the right. |

Its setup like you have described except it's half a tooth out for some reason.
Other than that, it won't fire up. |

The car is running! The camshaft timing was spot on.
The crank pulley is 5 degrees out due to 1/2 a tooth being out. It's running due to an ignition issue on the dizzy, it sounds like its running on 3 but its a start!! |
