i hope i am posting this in the right place. my problem is that i just installed a new engine on my car and now it will not start because i am not getting any spark.i have tested the coil pak and crank angle sensor. I have also replaced my cam angle sensor. my car is a 99 gs with the 420a motor. any ideas would be great

Welcome, make sure to get acquainted with the search feature of the site. All I did was type "no spark" in the search (and switched to search title only) and came up with a bunch of threads. Check those out.

im thinking your timing is off.....i had the same problem after putting an engine in my car and it wouldnt start......i got it fires a few times....i went though everything and i had no spark either..

i checked the timming and it was a tooth off, i redid it and it fired right up.......

im not sure, correct me if im wrong, but i think the cam sensor and crank angle sensor work together and send a signal to power the coil pack and send spark....if timing is off it wont send the right signal

I know it's that way on the later production ones, on my early 95 it'll fire even if you have the cams 180* out

Does your car have an alarm?

that would be funny in a way......all the trouble of finding out what it is, and it is the alarm :scratch

i have not checked the timing because the engine came with the timing belt on it but i will check it tonight and my car does have an alarm but i belive that it is working fine and also i asked the people at a local alarm store and they said that an alarm could not cause it because alarms only have starter disable.I will check my timing tonight when i get home and if anyone knows more about how an alarm could cause it let me know i dont know very much about my alarm because it came with the car all i know is that it is a hornet

It may have a starter kill that would interupt the ground to your starter relay under your radio.

It happened to me.

the starter is working so its not the starter kill switch the problem is that ther is no power going to the coil i was going to check the timing but i could only see the marks on the cams not the one on the crank. i was going to take the harmonic balancer of to check but it started raining the marks on the cam gears do line up im not sure about the one on the crank yet im going to have to wait till tomorow to check

Ok so i had a friend check all of my wiring and he said that its my ECU. My problem now is that some of the junk yards are saying that 96-99 have the same ECU and some are saying 98-99 and i even had one say that only 99 would work does any one know what the right answer is
