Changing a Distributor on a 1990 Celica?

I was driving my celica wen it suddenly the engine light came on and the car just die. When I try to turn it on, it looks like it wants to turn on, but it don't have no spark whatsoever. So I took it to this shop, and they did their thing and diagnosed with a bad distributor. I had that distributor changed 3 months ago by a friend, Now I would like to change it myself. The only tricky part is the timing, if i mess the timing how can i fix it?Changing a Distributor on a 1990 Celica?
Set the crankshaft pulley timing mark to TDC. Remove the distributor cap and check that the rotor is pointing to the #1 plug wire. If not rotate the crankshaft 360 degrees and check the rotor position again. Note the mark in the lip of the distributor housing that should now be aligned with the rotor. Loosen the distributor clamp and pull the distributor out. You can gently twist the distributor left and right while pulling to help it come out. Just as the rotor stops moving as you pull the distributor out, note where the rotor is pointing by referencing it to a part on the motor. This will help you set the new distributors rotor position before putting it back into the distributor drive gear. If the rotor does not line up with the mark on the distributor housing, remove it and turn the rotor slightly in the direction needed to align it correctly. Once you have the distributor back in, put the cap back on, start the motor and set the timing with a timing light. You need to double check the timing when the motor is at operating temperature and you will need to find out if there is a vacuum line that needs to be pulled off and plugged or if there is a wire that needs to be disconnected or jumped to set the base timing correctly.Changing a Distributor on a 1990 Celica?
If you havent done it have a pro mechanic do it. Obviously dont let your friend change it again. and if u do it yourself just mark which wires came from where and the cap has a mark on it. its not a very tough job.
after driving over 40 yrs ive yet to wear one out but you must bump the motor over to line mark timing mark on bittom pulley then you must set in distributor with rotor pointing at number one plug wire best you have it done
a timing light used at night will help to set the timing right. if the blue light flashes, the timing is off. You adjust the timing until you get a steady blue light. If you are not experienced in engine repair, I would have someone who knows more about the car do this, as you can possibly damage the timing belt or chain.
